I love when you search the oddest combo of words in TH-cam and you find exactly what you are looking for 😂. We moved into our new home and thought our home inspector missed this and the previous owner’s didn’t disclose it. Inspector came back out but couldn’t detect any moisture. We wanted to be sure so we had a plumber come out and sure enough they said the exact same thing you did. It’s pretty annoying but I’m glad it’s not a leak. This bathroom is over the dining room so water damage on the second floor would have been awful! It was comforting to hear the same sound in your video so I knew I wasn’t losing it. Thank you!
i know this is an old video, but that explains so much. been looking in walls and under house. hands on pipes. no signs of water, but drip drip drip. now i get it. thanks
Thank you so much! I’m a new homeowner and this is my first winter in my house. The “drip” noise is so loud and you can feel it if you press your ear to the wall. I was panicking I’d have to open up my walls to find this mystery leak.
Very common, especially with new construction. You have PVC, which is plastic drain pipes and they make even a louder sound because we have to put a fireproofing sealant around the pipe as it passes through each floor of the home which magnifies the thermal expansion sounds.
5:53 that’s exactly the sound I’ve been hearing. No leaks anywhere. Exactly the same spot too, near the kitchen cabinets. I’ve been trying to find videos about this exact problem. Thank you for posting.
My pleasure happy to help! Yeah, out of all the videos I’ve made this one seems to be the most helpful because a lot of people experienced this, and it can be worrying hearing what sounds like water leaking behind your walls.
This helped so much! I kept hearing a dripping noise. I have a tri level home and I would hear it next to my bed on the 3rd level and it was in the area that would run directly down to the water heater in the garage. I had a plumber come with their moisturizer radar thing and they couldn’t detect any moisture behind the walls and suggested exactly what you said. I was freaking me out thinking water damage was happening to my property. The noise still drives me crazy because we shower at night and can heard the dripping while in bed. Well it drives me crazy but my husband doesn’t seem to notice. I wish I saw this video a long time ago! Thank you for the thorough explanation
5:52 I am absolutely relieved after watching this video. The dripping water sound comes from my kitchen ceiling that gave me sleepless nights. Sigh of relief finally.
Thank you! I’ve been hearing this for a year but realized it’s only when the heat/ furnace is on and it’s by the soffit/ drop ceiling area. I wish I could give you three thumbs up!
Your video saved me from making holes in the drywall to find the water leak. The explanation and examples were spot on and they were exactly same as my sound. Thank you so much!

Great educational video. Very appreciated. I've been worrying about this for months. Did what you recommended and yes it only happens when hot water is turned on. Last for a while and then stops when running out of hot water. Meaning water starts to cool. You know your stuff and know how to educate. Thanks.
Thanks Sir!! Just moved into a 50 years old house, the plumbing was re-done but when I heard the dripping sound I panicked! I found no hint of water or moisture so your video explains what it is going on. All the best!
This is the best explanation of this phenomenon I’ve ever heard. Thank you. My house makes this noise and I’ve been tempted to tear out the drywall to find out what’s going on. Now I’ll settle in with another cup of coffee and the newspaper.
You saved me from this video! I had the same exact problem and my own contractor couldn't find the issue _ _ I almost broke my kitchen sink wall and still could not use a new dishwasher bc of this issue! Thank you again!!!!
Thankyou very much. I thought I was going crazy. I have that exact same dripping sound and it's also next to my sink, about the same area where yours is. With no signs of water damage. Thank you so much. Great video 🙂
Wow! So thermal expansion is the answer. Very informative and such a well presented video. I feared I had pests in the wall, shoddy plumbing work, or that moisture was developing somewhere I couldn’t see. My daughter and I are so relieved. We’ll shower earlier in the evening to avoid all the noises around bedtime now.
My pleasure! Yeah, I know it can be pretty nerve-racking, and deceiving because it really sounds like a water dripping noise. Happy to hear you liked the video!
Oh thank god, I figured it was something like this when I first heard the sound, but I wanted to be sure so I popped into youtube to look for answers and you came to the rescue... it sounds so much like dripping I freaked out! I calmed down a bit when I realised it was just making that sound when I turned on the hot water for more than a couple of minutes. This video just confirms it as it sounds exactly like the video your customer sent you. Thanks for the upload! 😅
TY. I have been hearing this drip sound coming from our bathroom, in the wall. We recently had the drain pipes for the bathroom sink and kitchen sink replaced with PVC b/c they were old and burst. When the weather changed to 50 and lower this drip sound started happening. Didn't happen when the pipes were installed (still warm weather then) and all of a sudden the noise happens when the weather drops. I have checked in the attic (as far as I could go), the bathroom, the toilet, and even the basement. No water damage (besides what was already there from the old pipes bursting). I can calm down now and stop worrying about another plumber bill.
This took a HUGE weight off my mind. I'm literally awake at 4am because I've been hearing this exact dripping sound near the AC vent in the ceiling of my bedroom for months but their is no moisture. It only happens when the air conditioner is blowing at night. Thank you SO MUCH for this video. Now I can rest knowing its not a water leak in the ceiling. 😴
Thanks for the video. Been getting paranoid recently with dripping noise but not seeing any signs of water damage… but this makes sense as to what’s happening
My sister and I just removed a sheet of drywall behind her sink to find the “leak”. There was no sign of water damage. Most of the pipes had an isolator where they ran thru the 2x4s. Where there wasn’t an isolator, the hot water supply line was squeaking against the wood and making that dripping sound. I padded it with excess insulation and the sound is gone now. This video confirms our conclusion. Thanks!
Hi， Just want to drop a note and thank you for this very informative and helpful video. Saved me hours of work to cut open walls. From the your description and comments, seems like it is a very common problem. I am surprised that it is not pointed out more often on any websites or videos. I almost feel this should be the first/second thing people check. Well, thanks again.
So I've had my house for 5 years, and never noticed this until about the past year. Went behind the escutcheons and couldn't find any evidence. FF to a couple weeks ago, and I had water stains on my living room ceiling. Coming from shower arm; doped it up and threads are sealed. Still hear this dripping sound...Put holes on both sides of my stud in my bath...no signs. Came across this video, and I can finally feel better. Thanks for this (esp the hot water) video! Now to patch some drywall...
Wow thank you. Definitely had a panic attack when I heard that noise, literally same sound I heard in your video and it was after the house had sat and just turning on the hot water.
Excellent post! I struggled with that same issue for years! Dip Dip...no water...where's the leak. I called a plumber and he looked at it...he brought up it could be just the hot water pipe. So I looked up this video to see if this could be real. Your last to two videos are the exact same sound! thank you so much! The plumber cost me $95 but he was correct.
I’ve been having this problem and freaking out thinking water was dripping in my ceiling. Had plumbers come 3 times for 3 different areas in my house of that noise. But, it’s not when using hot water. It’s anytime any water is being used: washing dishes, washer, shower, faucet, and even flushing the toilet. Also, when no water is being used you can hear 1 loud drip every 40seconds or so. Plumbers still can’t find anything. No leaks, nothing. I can’t stress this enough.
Hi Leah- Well it’s possible it’s not the plumbing and your possibly your heating and air-conditioning system. This video pertains to both plumbing pipes and heating and air condition ductwork expanding and contracting, making these various types of sounds one of which my sound like dripping water. If you have a plumbing leak unless if your situation is a one off scenario more than likely you will eventually see signs of a leak. So for now just continue to monitor until you see it water stains on your ceilings, walls, or floors. Hope this helps!
Did you ever figure out what was the noise? Curious because i have the same issues especially when I flush the toilet and the water is filling the tank up.
@@jonlim497 I had plumbers come out again, apparently did a temp fix because we're back at square one. The only thing possible is needing a rubber isolator to vibrationally isolate the piping from any surrounding surfaces the pipes can knock against. Mind you, my house is not even a year old with these problems, something may have came loose.
Yeah, what’s tough nowadays with the fire safety codes. In most municipalities all penetrations between each floor have to be sealed, which restricts the pipe or duct from expanding and contracting freely adding to the noises you’re hearing.

Wow thank you so much ! This is it! Sounds exactly like it in that kitchen video. It was at night when the dish washer ran or in the shower. In closet ceiling. I didn’t notice it my first 2 years in my new build house. Could it have just settled in over 2 years and start doing this? Heard this noise for months with no water damage. Yep only when hot water is on.
thank you sir. I was underneath of my house three times with a borescope and a moisture sensor - no leaks found. It's constant but annoying. Now I know what it is.
omg.. I have exactly the same dripping noises behind the wall when I open the tap or after a shower. I was ready to order an endoscopic camera and/or open the walls.. thanks Buddy! from UK
Thank you so much for the video, from Europe! I recently purchased a house, this sound appears every time when I used the hot water (first very frequent then slow down). I am being so mad and driving crazy 😢😢😢. Thanks for making this explanation!!!
Hi, BJ, May I ask whether it is normal that when I turned off the hot water pipe, the water drip sound started, and then become less and less frequent. It does not have any sounds when I start & stop cold water. Would it be possible for me to send you the video? It’s copper piper in the wall 😢
Thanks so much!! I made holes in the drywall in basement ceiling then stairs then upstairs, bought flir infrared camera, bought endoscopic camera, put camera thru walls all from top to bottom of the house next to pipes, under bathtub from valve small door access looked for wet spots anything... NOTHING FOUND!!! had to patch up all walls, and still couldnt find any leakage. Until my wife showed me that video!!
@@xjcrossx Yeah, not needed. Unless you’re seeing signs of a leak such as staining on the ceiling, water on the floor, wet carpet, etc. more than likely you’re situation it’s just thermal expansion of your ductwork or plumbing drains.
BJ thank you, thank you!. I started hearing that dripping sound after I had my basement refinished. Prior to the refinish there wasn't a basement ceiling. The noise is audible when the furnace is heating and stops running.. I noticed it first in the basement, around a main vent which runs from one end of my home to the other and more vents branch out from that one. My fear was I thought water was seeping in from somewhere, but never saw any water stains or leaks. I've turned off the humidifier on the furnace thinking condensation was getting in some how. After watching your video, I had a few A HA moments. When the carpenter was finishing the basement ceiling, he framed around this particular vent with 2x4 wood, I thought it looked too bulky, I asked him if he could use smaller framing material and he obliged me. SMH. He removed it and used metal around that vent. It was so snug, you couldn't fit a piece of paper between the metal framing and the vent, the finished ceiling looks amazing. Next, fire stop had to be added to pass inspection. It is a 1973 solid brick ranch home, that wasn't required when initially built. I lived in the basement for a year until the main floor bathrooms were done. They've been completed and now I sleep in the upstair bedrooms. Its been a month sleeping on the main level and I hear that drip. Yep, 4:00 am on the internet trying to solve this problem, at least understand it. You're correct, the expansion space that was there, is no longer there, per my request.😢😢 plus, the section of the main floor above that metal framed sectione is creaky and a little weakened. Your explanation makes so much sense, that dripping sound is most prevalent around where the metal framing is and it echoes throughout. Thank you so much, I will be getting that fixed, but in the meantime I have a little peace of mind, not water. Thanks again BJ
BJ, you are fantastic. Thanks for addressing this issue. The question is: how do you eliminate this? I just spent a year renovating my home - a luxury custom home at that. And, I have this issue. I am working with my builder, however I just don't think we are making headway. Your suggestions and recommendations are welcome!
Thank you Iron Sisters. Unfortunately I hate to be the bearer of bad at this point there is nothing that you can do. Unless you wanna go tearing up a freshly renovated house on a wild goose chase. During construction there are few steps that could’ve been taken in an attempt to possibly minimize the thermal expansion noises, however in your builders defense even if they did take some of these steps such as install thicker gauge ductwork, install different drain pipe material, etc. it’s not guaranteed would solve the problem.
@@BJPoznecki I appreciate the time responding. We’ve done some of that work already … of course I know more about “building” now than before - not an expert by any means, but I certainly understand the value of using quality materials on internal components - they are equally as important as finishes. That said, insulating those mechanical runs/cavities and possibly adding insulation to ducts/pipes (wish we’d stayed with cast iron) is extra insurance to keep noises minimized too. Plus making those cavities a tad bigger too - as you mentioned - to keep things from hitting one another is useful if possible. In our case we had the room to do all of this but unfortunately these sounds weren’t anticipated and so none of this done. I hope folks watching your video are able to catch some of these things in the future during construction phases if possible, so perhaps this video and your comment thread will help someone down the road. Thanks again and keep up the great work! P.s. got my builder adding weather stripping to my vent flaps now as well thanks to another one of your vids 🙌
@@IronSisters Thank you for the kind words! Putting aside these noise nuisances I hope you enjoy your newly remodeled 🏡 and have a great first Christmas in it! 🎄🎅
That's such a relief BJ. That's exactly what my walls sounds like after my neighbor upstairs uses the shower or the toilet. Maybe I should stop using my heater in the spring time but it has been unseasonably cold where I live.
@@BJPoznecki Sorry one last question BJ. I noticed that when my neighbor uses the toilet now with the heat OFF that I hear the dripping sounds but a few seconds after I've heard the water flush down. I'm guessing the sounds happen after he washes his hands with hot water in the sink? I should probably check with him to test it out.
@@inigolacdan7314 Yeah, typically you won’t experience these noises with cold water, only with hot water. Yes, I would check with your neighbor and test it out. If you’re still uncertain I would submit a request with your maintenance or building manager and have them get involved.
Thanks sounds exactly what I hear...been that way for years but figured it wasn't a leak since no mold or deteriorated dry wall. At least I can explain when I sell
I had this issue, and I called a guy to check it out. He came by and as he walked into the house, he told me that it could be thermal expansion. It sounds just like water dripping. I hear the water dripping but couldn't find any water damage. I bought a endoscope to see inside the wall for water damage, but couldn't find anything. It just drove me crazy for a while. It still sounds like water dripping......
I'm having similar noise but noise comes when central heating is on 😅 your video helped me to understand that there is no leaks Hehe. Thank you for your vid
My pleasure Christopher! I see you’re a real estate agent. If you happen to be in the Chicagoland area and need a home inspector please keep me in mind.
I think/hope this is what I can hear I’ve been hearing it for months with no sign of damp or moisture. Mine sounds like faint rain on the window kind of sound dripping/crackling kind of sound could it still be this? Also it goes on for hours sometimes times I feel like I can hear it all day long with various degrees of volume
Hi Dave- It shouldn’t as long as you don’t have an active leak. As a courtesy you may want to share this video with the buyer and let them know that they may experience these thermal expansion noises, so this way they don’t get nervous when they move in and hear them.
Great video. Really has put my mind at ease. I hear this dripping (12-15 seconds apart) in ceiling when my bath sink is on for 5 minutes or so. It only happens when heat is on and stops a minute or so after it's off. Based on your comment, it sounds like expansion. Also hear it in ceiling when hot again when my garage utility sink on, again only hot water and stops a minute or so after it's shut off. Inspecting carefully around I see no damage of any kind. A question I'd like to ask, if there was a true leak wouldn't I hear that drip continue long after and not stop at all?... Anyways, thank you so much for this vid. This has been a thing for awhile now and so has my worry. Thanks to your video, hopefully I can relax now. Bless.
PrimitiveMeat- Typically if you have a plumbing leak you’ll see water stains on the ceiling, walls, etc. However, I have seen some unusual situations over my career, so I would run cold water at these 2 drains for an extended period of time like 30-60 minutes to see if anything leaks. If you aren’t able to create a leak than more than likely you’re just experiencing thermal expansion.
@@BJPoznecki Thank you. Haven't run cold that long, yet probably half that and never hear that drip sound other than hot water. Thanks so much, I'll try a bit longer duration next round. Bless.
It sounds like rain coming from my window but there's no rain outside it's driving me crazy.idk what it is! And it hasn't gone away passed couple days.
Hi BJ, I am a new subscriber, and I'm glad I ran into your video. My question is, what if the dripping water sound is heard from the ceiling in my bathroom just above that square compartment (not sure of the name), and this happened after it had just rained. Would it be considered thermal expansion or possible leak in my roof? There are no physical signs of any water.
@@veeoby3364 Thank you for subscribing! Well, if you have an openable access panel, it’s always best to take a look and visually see if there’s anything leaking. Typically, if you have a roof leak eventually you will see water staining on the ceiling karma, especially after a sizable rain event.
We are experiencing this thermal expansion in a pipes running through the duct work in our basement. We built a new home and it started within 6 months of the build. It only happens when we run hit water from our kitchen faucet. My plumber is suggesting we open up the dry wall where the noise is coming from an see if we can slightly reposition the pvc pipe so it has room to expand without rubbing up against the duct work. I guess this is our only option? Your thoughts would be much appreciated because the noise is terrible especially when we run the dishwasher. Thank you
Hi Phillip- What you’re experiencing is very common, especially with a new home. Yeah, unfortunately, that’s the only option is to open up the area and see if you can adjust the pipe, or modify it in someway to minimize the noise.
I have that sound but when it rains. I haven't found any water damage anywhere and I had a new roof installed a year and a half ago. It doesn't happen every single time it rains, just randomly so it's extremely perplexing.
Well, if you’ve never experienced this before with the old roof, and recently with the new roof. I would have the roofer come back out and inspect the whole roof and the attic just to see if there is any signs of water leaks anywhere.
Thanks for sharing this information! I have a dripping noice I hear in my basement. If I put my ear close to the floor it almost sounds like it's coming from the floor. I'll admint, my ears aren't the best at locating things. It's spring, and things are pretty dry outside. Everything is dry, can't see any signs, nothing after following your recommended steps. Any ideas? I only hear it from the basement. I haven't noticed it before. Do you have any thougts or suggestions? When I bought the home 20 years ago I do remember them saying there was a high water table or they would have made the basement larger, but I don't see any water anywhere!
Hi good video we recently had a bathroom redo anyways we laid new subflooring fixed the piping we even too.down the ceiling in our livingroom (the area where the bathroom is above) we had it open for months then put up drywall now hearing the same thing as in the video but no leaks
We just moved into new home which is 20 year old house and whenever I run the water I hear this drip drip drip sound and then sound slowly stops when I turn the tap off. It is two story house and the ceiling doesn’t look like have any damage but this dripping sound really bothers me because whenever I use the tap water upstairs and downstairs all the ceiling makes dripping sound. Plumber is going to come tomorrow just to check every pipe hopefully there is no leak.
In my new home, whenever I flush the toilet on the second floor, I consistently hear a dripping sound coming from somewhere inside the wall on the ground floor. Despite the fact that the toilet flush doesn't involve hot water, this sound persists. I haven't observed any visible signs of water leakage. What could be causing this issue? It's concerning that the builder seems to be disregarding it completely.
You can also experience reverse thermal expansion where cold water is running through a pipe that’s warm. A lot of times you could have a drain pipe in the same joist cavity as your ductwork to where in the winter you’re running the heat and it’s heating up that area where your drain pipe is, so when you run cold water you’re cooling off the pipe and it’s contracting. What I would do is turn the heat off and turn everything on in that bathroom the sink, tub, shower, flush the toilet a bunch of times, etc., and let the water run for a good 30 minutes. Then, see if anything leaks, and/or if the noises stop once the pipe is cold. Let us know how it goes?
It very well could be reverse thermal expansion. Where the pipe is warm and when you run cold water it contracts making sounds as well. Unfortunately the only way to fix it is to try and locate where the sound is coming from and open up the area to see if you can modify it, and then put everything back together.
I've had something similar, but my water bill. Also went from two thousand gallons of water to over eight thousand gallons of water. I have a plumber coming tomorrow for an apartment unit that I rent because they refuse to do anything. I wastimg 200$ having a plumber come?
No I don’t think it’s a waste having a plumber come I think it’s a great idea because if your water bill jumped from 2000 to 8000 gallons, there’s water running somewhere. If you’re not seeing any water damage anywhere a common thing I see is toilets continuously running and not turning off because either the flapper or fill valve inside the tank up top your toilet need to be replaced.
@@BJPoznecki thank you, I can hear water dripping in the wall and water heater. And the pipes make crazy dripping sounds when I use my kitchen sink hot water, only my kitchen sink hot water though. I really appreciate your response and assurance.
My newly built apartment developed this noise in my walls a few months after I moved in. Whenever myself or one of my neighbors flushes the toilet, there’s a very loud tapping noise in my wall. So loud that it wakes me up at 5:30-6:30am when my neighbors are up and getting ready for work in the morning. So frustrating that there’s nothing we can do about it. I use a box fan sound on my phone to drown out the noise every night 😂
Yeah, you might get lucky and be able to open up the ceiling or walls and try to make some modifications to quiet it down, but it’s a crapshoot. Typically it’s louder in the middle of the night because there’s no background noise so it’s more pronounced and noticeable when everything is dead silent.
@@BJPoznecki thanks for the response! I’ve heard this dripping sound for almost a year so for sure it’s not water. Are there any questions I should ask before hiring them?
Hello Mr. BJ, my problem is whenever I turn on the AC cuz it's hot summer now, I haven't tried heat, so now I turn on the AC, I heard the dripping sound in the wall like yours, once I turn off the AC, the dripping sound will slowly disappear , which is really like water dripping. In order to make sure my problem is the one you shared, would you please share your contact information with me so I can send you the video of my dripping or schedule an appointment to check it onsite if it's necessary? Thank you so much!
@@MollyGuo-y3h Hi Molly, for your situation it sounds like your air conditioner is leaking so you’ll want to call an HVAC technician to come out and service your unit.
In your case, being that you guys just installed a new faucet. I would double check to make sure nothing is leaking. If nothing is leaking. It’s thermal expansion and the only way to try to get rid of it would be to have a plumber, modify the piping, in which it’s not a guarantee it’s going to go away.
I'm having the exact same problem right now in my condo everything you're describing. not only I'm hearing that knocking sounds and also the water running inside the pipes in the ceiling and walls above me. I'm frustrated I have hired multiple plumber and heating company. they had me bleeding the pipes, change the flapping valve inside the toilet, change the fluid master in the toilet bowl. specially at night i haven't had a goodnight rest in months, to the point now I'm putting the place for sell. they have a 1/4inch drywall, the pipes are pvc, it's horrible the extent the builder go to save money. a few plumber told me it's a permanent problem, the best thing for me to do tear down the ceiling and walls and insulating everything. IS THERE ANYTHING else I can do to fix this until I get rid of the place.
I’m sorry to be the bearer of bad news, but unfortunately the plumber and the heating and air-conditioning contractors are right. Trying to find exactly where the noises are coming from entails opening up walls and ceilings In the process.
I hear about 15 drips after flushing the upstairs ensuite toilet only. I am aware that after our reno that this drain pipe has quite a slope at one point, however I hear the noise at the area where there is another pipe that joins to the hall bathroom. Note that I don't hear this noise after using the showers, the other toilet or the 3 taps. There is no moisture noted anywhere. Could this still be the problem?
Hi Rese- Sorry for the delayed response. What I would try doing is flushing that one toilet only multiple times to see if you can create a leak. If you’re not seeing any signs of a leak anywhere, it’s very possible that the drain pipe that toilet leads into is in a wall where it’s maybe warm and the cold water from the toilet makes it contract making those sounds. What you could always try doing is running a lot of cold water from that bathroom turn everything on the sinks, shower, toilet, etc. and run a ton of cold water and see if after a certain point that you stop hearing that dripping noise, or a leak presents itself. More than likely what you’re experiencing is just thermal expansion, however, I always like to play it safe and rule out anything leaking because there is always a possibility there could be a leak somewhere.
It just started happen when my air goes on idle. “Dripping sound “ but no water anywhere . On my big air vent ,,, next to my fridge. It’s only WHEN MY AIR CONDITIONER GOES IN IDLE . So this is nothing to worry about ? 😮 tell me I have nothing to worry about pls.
Well, I would look into the vent, or take it off if you have to, and see if there’s any signs of water dripping. I actually did have a leak with my air conditioner once before, so It’s always best to investigate as much as you can, and if you don’t find anything, continue to monitor it until you know for sure.
I love when you search the oddest combo of words in TH-cam and you find exactly what you are looking for 😂. We moved into our new home and thought our home inspector missed this and the previous owner’s didn’t disclose it. Inspector came back out but couldn’t detect any moisture. We wanted to be sure so we had a plumber come out and sure enough they said the exact same thing you did. It’s pretty annoying but I’m glad it’s not a leak. This bathroom is over the dining room so water damage on the second floor would have been awful! It was comforting to hear the same sound in your video so I knew I wasn’t losing it. Thank you!
Thank you happy to hear it was helpful!
2yrs and still this post is valid!🎉
Yes! This is exactly what is happening here! Wish I had seen this months ago!
I thought my house was haunted lol
i know this is an old video, but that explains so much. been looking in walls and under house. hands on pipes. no signs of water, but drip drip drip. now i get it. thanks
My pleasure, I know it can be deceiving the sounds the pipe make, sound just like dripping water.
Thank you so much! I’m a new homeowner and this is my first winter in my house. The “drip” noise is so loud and you can feel it if you press your ear to the wall. I was panicking I’d have to open up my walls to find this mystery leak.
Very common, especially with new construction. You have PVC, which is plastic drain pipes and they make even a louder sound because we have to put a fireproofing sealant around the pipe as it passes through each floor of the home which magnifies the thermal expansion sounds.
5:53 that’s exactly the sound I’ve been hearing. No leaks anywhere. Exactly the same spot too, near the kitchen cabinets. I’ve been trying to find videos about this exact problem. Thank you for posting.
My pleasure happy to help! Yeah, out of all the videos I’ve made this one seems to be the most helpful because a lot of people experienced this, and it can be worrying hearing what sounds like water leaking behind your walls.
@@BJPoznecki I feel like I hear it more after I run the shower or dishwasher.
@@AKAMRAKA Yeah, very common because you’re using hot water with the shower and the dishwasher which causes the pipe to expand.
Thank you so much. I always thought I was going crazy and was paranoid. I have regular plumbing inspections, but this makes me feel SO MUCH BETTER.
Thank you so much for posting this video! I was thinking I had water leak in my attic but I do not! This is so educational, Thank you!
My pleasure, thank you for watching!
This helped so much! I kept hearing a dripping noise. I have a tri level home and I would hear it next to my bed on the 3rd level and it was in the area that would run directly down to the water heater in the garage. I had a plumber come with their moisturizer radar thing and they couldn’t detect any moisture behind the walls and suggested exactly what you said. I was freaking me out thinking water damage was happening to my property. The noise still drives me crazy because we shower at night and can heard the dripping while in bed. Well it drives me crazy but my husband doesn’t seem to notice. I wish I saw this video a long time ago! Thank you for the thorough explanation
Thank you for the nice compliment Rach!
5:52 I am absolutely relieved after watching this video. The dripping water sound comes from my kitchen ceiling that gave me sleepless nights. Sigh of relief finally.
Thank you! I’ve been hearing this for a year but realized it’s only when the heat/ furnace is on and it’s by the soffit/ drop ceiling area. I wish I could give you three thumbs up!
Thank you Alexis! 🙏🏼
Hey so how did you fix that ?
Your video saved me from making holes in the drywall to find the water leak. The explanation and examples were spot on and they were exactly same as my sound. Thank you so much!

Great educational video. Very appreciated. I've been worrying about this for months. Did what you recommended and yes it only happens when hot water is turned on. Last for a while and then stops when running out of hot water. Meaning water starts to cool. You know your stuff and know how to educate. Thanks.
Thank you for the compliment I’m happy to hear you liked the video and found it helpful!
Thanks Sir!! Just moved into a 50 years old house, the plumbing was re-done but when I heard the dripping sound I panicked! I found no hint of water or moisture so your video explains what it is going on. All the best!
Congratulations on the new house! Thank you I’m happy to hear you liked the video and found it helpful!
This is the best explanation of this phenomenon I’ve ever heard. Thank you. My house makes this noise and I’ve been tempted to tear out the drywall to find out what’s going on. Now I’ll settle in with another cup of coffee and the newspaper.
Thank you! Enjoy ☕️📰
Thank you for the video and recording the sound.
You saved me from this video! I had the same exact problem and my own contractor couldn't find the issue _ _
I almost broke my kitchen sink wall and still could not use a new dishwasher bc of this issue!
Thank you again!!!!
Thank you for explaining this for us simple folks.
Thankyou very much. I thought I was going crazy. I have that exact same dripping sound and it's also next to my sink, about the same area where yours is. With no signs of water damage. Thank you so much. Great video 🙂
My pleasure thank you for the compliment Sean!
Wow! So thermal expansion is the answer. Very informative and such a well presented video. I feared I had pests in the wall, shoddy plumbing work, or that moisture was developing somewhere I couldn’t see. My daughter and I are so relieved. We’ll shower earlier in the evening to avoid all the noises around bedtime now.
Thank you TeeTee!!
Thanks for this video. It’s a nightmare to hear that water dripping noises and not diagnose any water leak.
My pleasure! Yeah, I know it can be pretty nerve-racking, and deceiving because it really sounds like a water dripping noise.
Happy to hear you liked the video!
Oh thank god, I figured it was something like this when I first heard the sound, but I wanted to be sure so I popped into youtube to look for answers and you came to the rescue... it sounds so much like dripping I freaked out! I calmed down a bit when I realised it was just making that sound when I turned on the hot water for more than a couple of minutes. This video just confirms it as it sounds exactly like the video your customer sent you. Thanks for the upload! 😅
Thank you for the nice comment, it’s my pleasure. Happy to hear the video was helpful.
You just saved my day! Thank you!
have this in my house too and was scared it was a leak. no water damage anywhere so was completely clueless. thank you for this.
TY. I have been hearing this drip sound coming from our bathroom, in the wall. We recently had the drain pipes for the bathroom sink and kitchen sink replaced with PVC b/c they were old and burst. When the weather changed to 50 and lower this drip sound started happening. Didn't happen when the pipes were installed (still warm weather then) and all of a sudden the noise happens when the weather drops. I have checked in the attic (as far as I could go), the bathroom, the toilet, and even the basement. No water damage (besides what was already there from the old pipes bursting). I can calm down now and stop worrying about another plumber bill.
@@ivoryherman My pleasure I know it can be daunting because it literally sounds exactly like dripping water.
This took a HUGE weight off my mind. I'm literally awake at 4am because I've been hearing this exact dripping sound near the AC vent in the ceiling of my bedroom for months but their is no moisture. It only happens when the air conditioner is blowing at night. Thank you SO MUCH for this video. Now I can rest knowing its not a water leak in the ceiling. 😴
@@Kaeco111My pleasure, sweet dreams!
Thanks for the video. Been getting paranoid recently with dripping noise but not seeing any signs of water damage… but this makes sense as to what’s happening
My sister and I just removed a sheet of drywall behind her sink to find the “leak”. There was no sign of water damage. Most of the pipes had an isolator where they ran thru the 2x4s. Where there wasn’t an isolator, the hot water supply line was squeaking against the wood and making that dripping sound. I padded it with excess insulation and the sound is gone now. This video confirms our conclusion. Thanks!
Hi， Just want to drop a note and thank you for this very informative and helpful video. Saved me hours of work to cut open walls. From the your description and comments, seems like it is a very common problem. I am surprised that it is not pointed out more often on any websites or videos. I almost feel this should be the first/second thing people check. Well, thanks again.
So I've had my house for 5 years, and never noticed this until about the past year. Went behind the escutcheons and couldn't find any evidence. FF to a couple weeks ago, and I had water stains on my living room ceiling. Coming from shower arm; doped it up and threads are sealed. Still hear this dripping sound...Put holes on both sides of my stud in my bath...no signs. Came across this video, and I can finally feel better. Thanks for this (esp the hot water) video! Now to patch some drywall...
Happy to help, Sean!
Wow thank you. Definitely had a panic attack when I heard that noise, literally same sound I heard in your video and it was after the house had sat and just turning on the hot water.
My pleasure happy to help!
Thank you, thank you, thank you!!! It was driving me nuts hearing that dripping sound but never seeing any sign of a leak.
You’re welcome, you’re welcome, you’re welcome!!! 🤣🤣🤣 Happy to help!
Excellent post! I struggled with that same issue for years! Dip Dip...no water...where's the leak. I called a plumber and he looked at it...he brought up it could be just the hot water pipe. So I looked up this video to see if this could be real. Your last to two videos are the exact same sound! thank you so much! The plumber cost me $95 but he was correct.
My pleasure Craig happy to help! 👊🏼
So that is issue? Do we need to fix it? Or it is normal?
Oh my gosh, thank you for this information!
Good clean video- informative, good presentation skills and a display of confidence/trust.
Thanks for the compliment Tom!
Thank you so much. I thought I was crazy but you gave me a peace of mind excellent video
Thanks TC!
thank you so much for doing this video! it helps so much!
hearing the exact same sound in our brand new apartment. i hope its just a normal thing. thankful for this video!
Omg you are the best. I recently purchased a new house and in my bathroom and I have the same issue. I was really worried but you definitely help me
I’ve been having this problem and freaking out thinking water was dripping in my ceiling. Had plumbers come 3 times for 3 different areas in my house of that noise. But, it’s not when using hot water. It’s anytime any water is being used: washing dishes, washer, shower, faucet, and even flushing the toilet. Also, when no water is being used you can hear 1 loud drip every 40seconds or so. Plumbers still can’t find anything. No leaks, nothing. I can’t stress this enough.
Hi Leah- Well it’s possible it’s not the plumbing and your possibly your heating and air-conditioning system.
This video pertains to both plumbing pipes and heating and air condition ductwork expanding and contracting, making these various types of sounds one of which my sound like dripping water.
If you have a plumbing leak unless if your situation is a one off scenario more than likely you will eventually see signs of a leak.
So for now just continue to monitor until you see it water stains on your ceilings, walls, or floors.
Hope this helps!
Did you ever figure out what was the noise? Curious because i have the same issues especially when I flush the toilet and the water is filling the tank up.
@@jonlim497 I had plumbers come out again, apparently did a temp fix because we're back at square one. The only thing possible is needing a rubber isolator to vibrationally isolate the piping from any surrounding surfaces the pipes can knock against. Mind you, my house is not even a year old with these problems, something may have came loose.
Thank you Leah for the response and hope everything works out. The noise is very irritating when you can't figure out what the source is.
Yeah, what’s tough nowadays with the fire safety codes. In most municipalities all penetrations between each floor have to be sealed, which restricts the pipe or duct from expanding and contracting freely adding to the noises you’re hearing.
Exactly I have the same thing in my house, that is why I search youtube on this. Thanks so much for saving me $150 from hiring a plumber to inspect.
My pleasure!

Wow thank you so much ! This is it! Sounds exactly like it in that kitchen video. It was at night when the dish washer ran or in the shower. In closet ceiling. I didn’t notice it my first 2 years in my new build house. Could it have just settled in over 2 years and start doing this? Heard this noise for months with no water damage. Yep only when hot water is on.
@@cnh7262 Yeah, it’s possible that something may have shifted, and now it makes that noise a little bit more pronounced than before.
@@BJPoznecki thanks again, I was seriously about to cut into the drywall, but 100% this is what it is.
thank you sir. I was underneath of my house three times with a borescope and a moisture sensor - no leaks found. It's constant but annoying. Now I know what it is.
omg.. I have exactly the same dripping noises behind the wall when I open the tap or after a shower. I was ready to order an endoscopic camera and/or open the walls.. thanks Buddy! from UK
My pleasure Govenor happy to help! 🍻
Thank you so much for the video, from Europe! I recently purchased a house, this sound appears every time when I used the hot water (first very frequent then slow down). I am being so mad and driving crazy 😢😢😢. Thanks for making this explanation!!!
My pleasure, happy to hear the video was helpful!!
Hi, BJ, May I ask whether it is normal that when I turned off the hot water pipe, the water drip sound started, and then become less and less frequent. It does not have any sounds when I start & stop cold water. Would it be possible for me to send you the video? It’s copper piper in the wall 😢
@@ginkgo1603 Of course if you’re in the states you can text it to 773-403-3298 or my email is bj@inspect-n-check.com
Thanks so much!! I made holes in the drywall in basement ceiling then stairs then upstairs, bought flir infrared camera, bought endoscopic camera, put camera thru walls all from top to bottom of the house next to pipes, under bathtub from valve small door access looked for wet spots anything... NOTHING FOUND!!! had to patch up all walls, and still couldnt find any leakage. Until my wife showed me that video!!
Sorry to hear you went through all of that for finding this video. Happy to help!
Haha i'm looking at about 5 holes in various places that I stuck my endoscope lol. Was looking at rentals for infered camera.
@@xjcrossx Yeah, not needed. Unless you’re seeing signs of a leak such as staining on the ceiling, water on the floor, wet carpet, etc. more than likely you’re situation it’s just thermal expansion of your ductwork or plumbing drains.
Thank you very much for this video! Saved me money! Great detailed information.
Thank you I’m happy to hear it was helpful!
BJ thank you, thank you!. I started hearing that dripping sound after I had my basement refinished. Prior to the refinish there wasn't a basement ceiling. The noise is audible when the furnace is heating and stops running.. I noticed it first in the basement, around a main vent which runs from one end of my home to the other and more vents branch out from that one. My fear was I thought water was seeping in from somewhere, but never saw any water stains or leaks. I've turned off the humidifier on the furnace thinking condensation was getting in some how.
After watching your video, I had a few A HA moments. When the carpenter was finishing the basement ceiling, he framed around this particular vent with 2x4 wood, I thought it looked too bulky, I asked him if he could use smaller framing material and he obliged me. SMH. He removed it and used metal around that vent. It was so snug, you couldn't fit a piece of paper between the metal framing and the vent, the finished ceiling looks amazing. Next, fire stop had to be added to pass inspection. It is a 1973 solid brick ranch home, that wasn't required when initially built. I lived in the basement for a year until the main floor bathrooms were done. They've been completed and now I sleep in the upstair bedrooms. Its been a month sleeping on the main level and I hear that drip. Yep, 4:00 am on the internet trying to solve this problem, at least understand it.
You're correct, the expansion space that was there, is no longer there, per my request.😢😢 plus, the section of the main floor above that metal framed sectione is creaky and a little weakened. Your explanation makes so much sense, that dripping sound is most prevalent around where the metal framing is and it echoes throughout. Thank you so much, I will be getting that fixed, but in the meantime I have a little peace of mind, not water.
Thanks again BJ
My pleasure!
Yeah, if we frame tightly around the ductwork it just makes it even worse.
Happy to help Rain Maker!!
I heard dipping sounds in the ceiling when we used hot water. I can not sleep with noise. Thanks for sharing
My pleasure!! I’m happy to hear the video was helpful!
Same drives me crazy. Made me want to rip thru the wall
Thanks man. My house is doing the same exact thing! The "dripping" sound slows down after I turn the water off just like yours.
Kinda wish I had just googled for my problem before ordering an industrial endoscope and drilling holes in my ceiling. Thanks for making this video!
Thank you so much for such a detailed video. I wish you were in Connecticut or the New England area. Thank you thank you
My pleasure thank you for liking the video!
BJ, you are fantastic. Thanks for addressing this issue. The question is: how do you eliminate this? I just spent a year renovating my home - a luxury custom home at that. And, I have this issue. I am working with my builder, however I just don't think we are making headway. Your suggestions and recommendations are welcome!
Thank you Iron Sisters. Unfortunately I hate to be the bearer of bad at this point there is nothing that you can do. Unless you wanna go tearing up a freshly renovated house on a wild goose chase.
During construction there are few steps that could’ve been taken in an attempt to possibly minimize the thermal expansion noises, however in your builders defense even if they did take some of these steps such as install thicker gauge ductwork, install different drain pipe material, etc. it’s not guaranteed would solve the problem.
@@BJPoznecki I appreciate the time responding. We’ve done some of that work already … of course I know more about “building” now than before - not an expert by any means, but I certainly understand the value of using quality materials on internal components - they are equally as important as finishes. That said, insulating those mechanical runs/cavities and possibly adding insulation to ducts/pipes (wish we’d stayed with cast iron) is extra insurance to keep noises minimized too. Plus making those cavities a tad bigger too - as you mentioned - to keep things from hitting one another is useful if possible. In our case we had the room to do all of this but unfortunately these sounds weren’t anticipated and so none of this done. I hope folks watching your video are able to catch some of these things in the future during construction phases if possible, so perhaps this video and your comment thread will help someone down the road. Thanks again and keep up the great work! P.s. got my builder adding weather stripping to my vent flaps now as well thanks to another one of your vids 🙌
@@IronSisters Thank you for the kind words! Putting aside these noise nuisances I hope you enjoy your newly remodeled 🏡 and have a great first Christmas in it! 🎄🎅
thanks for the explanation- big help
Thank you for sharing this is what I have been hearing .
Thank you for posting this! 😀👍
That's such a relief BJ. That's exactly what my walls sounds like after my neighbor upstairs uses the shower or the toilet. Maybe I should stop using my heater in the spring time but it has been unseasonably cold where I live.
👍🏼 all good!
Very common when your neighbors above you shower with hot water 🚿
@@BJPoznecki That must be why it's worse in the morning. Pretty sure he takes long showers in the morning.
@@inigolacdan7314 🤣🤷🏻♂️🥶
@@BJPoznecki Sorry one last question BJ. I noticed that when my neighbor uses the toilet now with the heat OFF that I hear the dripping sounds but a few seconds after I've heard the water flush down. I'm guessing the sounds happen after he washes his hands with hot water in the sink? I should probably check with him to test it out.
@@inigolacdan7314 Yeah, typically you won’t experience these noises with cold water, only with hot water.
Yes, I would check with your neighbor and test it out. If you’re still uncertain I would submit a request with your maintenance or building manager and have them get involved.
Thanks! This gives me some perspective before bothering my plumber during the holidays. 😉
Thanks for your video. Everytime i turn on the tap water and shower , toilet. I heared that dripping sounds. But no leak.
Thanks sounds exactly what I hear...been that way for years but figured it wasn't a leak since no mold or deteriorated dry wall. At least I can explain when I sell
Happy to help my man 🤝
I had this issue, and I called a guy to check it out. He came by and as he walked into the house, he told me that it could be thermal expansion. It sounds just like water dripping. I hear the water dripping but couldn't find any water damage. I bought a endoscope to see inside the wall for water damage, but couldn't find anything. It just drove me crazy for a while. It still sounds like water dripping......
Haha. Yup. Drives me nuts. Furnace comes on and after it goes off I hear a tapping sound. Can’t pinpoint it. 😅
I'm having similar noise but noise comes when central heating is on 😅 your video helped me to understand that there is no leaks Hehe. Thank you for your vid
Excellent video! I was getting worried! Thanks for explaining everything!!!!
My pleasure Modasser.
Wishing you and your family a very merry Christmas! 🎄🎁❄️🥃
This video is the best
I hear it w both cold & hot water. Slow drips then stops after a few seconds.
Did you end up finding out what it was?
Very helpful information. Thanks
Thank you, I thought I was crazy too
You’re welcome! Nope, the only one that’s crazy is me! 😜🤣
If i'm already remodelling the room, should I replace the 40 years old metal pipes with Pex? Will plastic make less expansion noise?
Thank you!
Thanks for this information!!!
My pleasure Christopher!
I see you’re a real estate agent. If you happen to be in the Chicagoland area and need a home inspector please keep me in mind.
I think/hope this is what I can hear I’ve been hearing it for months with no sign of damp or moisture. Mine sounds like faint rain on the window kind of sound dripping/crackling kind of sound could it still be this? Also it goes on for hours sometimes times I feel like I can hear it all day long with various degrees of volume
I hear the same when I turn on the hot water. Now my home is going to have an inspection for a sale, I hope it wont hinder the sale.
Hi Dave- It shouldn’t as long as you don’t have an active leak.
As a courtesy you may want to share this video with the buyer and let them know that they may experience these thermal expansion noises, so this way they don’t get nervous when they move in and hear them.
Great video. Really has put my mind at ease. I hear this dripping (12-15 seconds apart) in ceiling when my bath sink is on for 5 minutes or so. It only happens when heat is on and stops a minute or so after it's off. Based on your comment, it sounds like expansion. Also hear it in ceiling when hot again when my garage utility sink on, again only hot water and stops a minute or so after it's shut off. Inspecting carefully around I see no damage of any kind. A question I'd like to ask, if there was a true leak wouldn't I hear that drip continue long after and not stop at all?... Anyways, thank you so much for this vid. This has been a thing for awhile now and so has my worry. Thanks to your video, hopefully I can relax now. Bless.
PrimitiveMeat- Typically if you have a plumbing leak you’ll see water stains on the ceiling, walls, etc. However, I have seen some unusual situations over my career, so I would run cold water at these 2 drains for an extended period of time like 30-60 minutes to see if anything leaks. If you aren’t able to create a leak than more than likely you’re just experiencing thermal expansion.
@@BJPoznecki Thank you. Haven't run cold that long, yet probably half that and never hear that drip sound other than hot water. Thanks so much, I'll try a bit longer duration next round. Bless.
It sounds like rain coming from my window but there's no rain outside it's driving me crazy.idk what it is! And it hasn't gone away passed couple days.
Hi BJ, I am a new subscriber, and I'm glad I ran into your video. My question is, what if the dripping water sound is heard from the ceiling in my bathroom just above that square compartment (not sure of the name), and this happened after it had just rained. Would it be considered thermal expansion or possible leak in my roof? There are no physical signs of any water.
@@veeoby3364 Thank you for subscribing! Well, if you have an openable access panel, it’s always best to take a look and visually see if there’s anything leaking. Typically, if you have a roof leak eventually you will see water staining on the ceiling karma, especially after a sizable rain event.
Still don’t love that noise, but we feel so much better with this explanation. The house is BONE DRY, but makes the same exact noises!
Yeah, I know I can be annoying, but I’m happy to hear nothing is leaking.
We are experiencing this thermal expansion in a pipes running through the duct work in our basement. We built a new home and it started within 6 months of the build. It only happens when we run hit water from our kitchen faucet.
My plumber is suggesting we open up the dry wall where the noise is coming from an see if we can slightly reposition the pvc pipe so it has room to expand without rubbing up against the duct work. I guess this is our only option? Your thoughts would be much appreciated because the noise is terrible especially when we run the dishwasher. Thank you
Hi Phillip- What you’re experiencing is very common, especially with a new home. Yeah, unfortunately, that’s the only option is to open up the area and see if you can adjust the pipe, or modify it in someway to minimize the noise.
Thanks this video really helped us out!
My pleasure!
I have that sound but when it rains. I haven't found any water damage anywhere and I had a new roof installed a year and a half ago. It doesn't happen every single time it rains, just randomly so it's extremely perplexing.
Well, if you’ve never experienced this before with the old roof, and recently with the new roof. I would have the roofer come back out and inspect the whole roof and the attic just to see if there is any signs of water leaks anywhere.
Lol funny at night I heard dripping sounds and I got freaked out and I yelled for my mom three times 😂
😆😆😆
Very helpful, thanks
Thanks for sharing this information! I have a dripping noice I hear in my basement. If I put my ear close to the floor it almost sounds like it's coming from the floor. I'll admint, my ears aren't the best at locating things. It's spring, and things are pretty dry outside. Everything is dry, can't see any signs, nothing after following your recommended steps. Any ideas? I only hear it from the basement. I haven't noticed it before. Do you have any thougts or suggestions? When I bought the home 20 years ago I do remember them saying there was a high water table or they would have made the basement larger, but I don't see any water anywhere!
This was very helpful
Thank you!
My newly built home has this issue. I HATE IT....every time the water is turned on in the upstairs, you hear this dripping...
Hi good video we recently had a bathroom redo anyways we laid new subflooring fixed the piping we even too.down the ceiling in our livingroom (the area where the bathroom is above) we had it open for months then put up drywall now hearing the same thing as in the video but no leaks
We just moved into new home which is 20 year old house and whenever I run the water I hear this drip drip drip sound and then sound slowly stops when I turn the tap off. It is two story house and the ceiling doesn’t look like have any damage but this dripping sound really bothers me because whenever I use the tap water upstairs and downstairs all the ceiling makes dripping sound. Plumber is going to come tomorrow just to check every pipe hopefully there is no leak.
Very helpful video, thank you man.
I have similar noises but with very filthy water emerging from somewhere (11 floor block of flats) into my bathroom through the bath and sink!
Sorry to hear that. I would call a plumber as soon as possible to come out and assess the situation.
I have a home that was built in 1968 and it does this when i flush the toilet and it lingers even when the toilet is not even running at all. Lol
In my new home, whenever I flush the toilet on the second floor, I consistently hear a dripping sound coming from somewhere inside the wall on the ground floor. Despite the fact that the toilet flush doesn't involve hot water, this sound persists. I haven't observed any visible signs of water leakage. What could be causing this issue? It's concerning that the builder seems to be disregarding it completely.
You can also experience reverse thermal expansion where cold water is running through a pipe that’s warm. A lot of times you could have a drain pipe in the same joist cavity as your ductwork to where in the winter you’re running the heat and it’s heating up that area where your drain pipe is, so when you run cold water you’re cooling off the pipe and it’s contracting. What I would do is turn the heat off and turn everything on in that bathroom the sink, tub, shower, flush the toilet a bunch of times, etc., and let the water run for a good 30 minutes. Then, see if anything leaks, and/or if the noises stop once the pipe is cold. Let us know how it goes?
I have this same sound with cold water as well .. had inspected by plumber and water restoration company.. no leaks found .. any suggestions ????
It very well could be reverse thermal expansion. Where the pipe is warm and when you run cold water it contracts making sounds as well. Unfortunately the only way to fix it is to try and locate where the sound is coming from and open up the area to see if you can modify it, and then put everything back together.
What if here this sound plus scratching sound at the same time In one area of the house ( master bedroom )
If you hear a scratching kind of sound inside the walls or the ceilings it may be a squirrel or mouse. I would call a pest control company.
I've had something similar, but my water bill. Also went from two thousand gallons of water to over eight thousand gallons of water. I have a plumber coming tomorrow for an apartment unit that I rent because they refuse to do anything. I wastimg 200$ having a plumber come?
No I don’t think it’s a waste having a plumber come I think it’s a great idea because if your water bill jumped from 2000 to 8000 gallons, there’s water running somewhere. If you’re not seeing any water damage anywhere a common thing I see is toilets continuously running and not turning off because either the flapper or fill valve inside the tank up top your toilet need to be replaced.
@@BJPoznecki thank you, I can hear water dripping in the wall and water heater. And the pipes make crazy dripping sounds when I use my kitchen sink hot water, only my kitchen sink hot water though. I really appreciate your response and assurance.
My newly built apartment developed this noise in my walls a few months after I moved in. Whenever myself or one of my neighbors flushes the toilet, there’s a very loud tapping noise in my wall. So loud that it wakes me up at 5:30-6:30am when my neighbors are up and getting ready for work in the morning. So frustrating that there’s nothing we can do about it. I use a box fan sound on my phone to drown out the noise every night 😂
Yeah, you might get lucky and be able to open up the ceiling or walls and try to make some modifications to quiet it down, but it’s a crapshoot.
Typically it’s louder in the middle of the night because there’s no background noise so it’s more pronounced and noticeable when everything is dead silent.
Who can I hire to come and check before we go wall tearing??
A plumber or heating and air conditioning contractor.
@@BJPoznecki thanks for the response! I’ve heard this dripping sound for almost a year so for sure it’s not water. Are there any questions I should ask before hiring them?
Thank you for your videos. I have the same problem , can i use pipe insulation to reduce the driping sound ?
Hello Mr. BJ, my problem is whenever I turn on the AC cuz it's hot summer now, I haven't tried heat, so now I turn on the AC, I heard the dripping sound in the wall like yours, once I turn off the AC, the dripping sound will slowly disappear , which is really like water dripping. In order to make sure my problem is the one you shared, would you please share your contact information with me so I can send you the video of my dripping or schedule an appointment to check it onsite if it's necessary? Thank you so much!
@@MollyGuo-y3h Hi Molly, for your situation it sounds like your air conditioner is leaking so you’ll want to call an HVAC technician to come out and service your unit.
@@BJPoznecki Hello Mr. BJ, thank you so much for your response. I will do that. Thank you!
This is what I hear all of a sudden at my vanity.. why did it start after I got a new faucet installed?? How can I stop it? Thanks!
In your case, being that you guys just installed a new faucet. I would double check to make sure nothing is leaking. If nothing is leaking. It’s thermal expansion and the only way to try to get rid of it would be to have a plumber, modify the piping, in which it’s not a guarantee it’s going to go away.
@@BJPoznecki Thanks. You're video is a blessing
@@danielleg2616 My pleasure!
I'm having the exact same problem right now in my condo everything you're describing. not only I'm hearing that knocking sounds and also the water running inside the pipes in the ceiling and walls above me. I'm frustrated I have hired multiple plumber and heating company. they had me bleeding the pipes, change the flapping valve inside the toilet, change the fluid master in the toilet bowl. specially at night i haven't had a goodnight rest in months, to the point now I'm putting the place for sell.
they have a 1/4inch drywall, the pipes are pvc, it's horrible the extent the builder go to save money.
a few plumber told me it's a permanent problem, the best thing for me to do tear down the ceiling and walls and insulating everything.
IS THERE ANYTHING else I can do to fix this until I get rid of the place.
I’m sorry to be the bearer of bad news, but unfortunately the plumber and the heating and air-conditioning contractors are right. Trying to find exactly where the noises are coming from entails opening up walls and ceilings In the process.
I hear about 15 drips after flushing the upstairs ensuite toilet only. I am aware that after our reno that this drain pipe has quite a slope at one point, however I hear the noise at the area where there is another pipe that joins to the hall bathroom. Note that I don't hear this noise after using the showers, the other toilet or the 3 taps. There is no moisture noted anywhere. Could this still be the problem?
Hi Rese- Sorry for the delayed response. What I would try doing is flushing that one toilet only multiple times to see if you can create a leak. If you’re not seeing any signs of a leak anywhere, it’s very possible that the drain pipe that toilet leads into is in a wall where it’s maybe warm and the cold water from the toilet makes it contract making those sounds.
What you could always try doing is running a lot of cold water from that bathroom turn everything on the sinks, shower, toilet, etc. and run a ton of cold water and see if after a certain point that you stop hearing that dripping noise, or a leak presents itself.
More than likely what you’re experiencing is just thermal expansion, however, I always like to play it safe and rule out anything leaking because there is always a possibility there could be a leak somewhere.
It just started happen when my air goes on idle. “Dripping sound “ but no water anywhere .
On my big air vent ,,, next to my fridge. It’s only WHEN MY AIR CONDITIONER GOES IN IDLE . So this is nothing to worry about ?
😮 tell me I have nothing to worry about pls.
Well, I would look into the vent, or take it off if you have to, and see if there’s any signs of water dripping. I actually did have a leak with my air conditioner once before, so It’s always best to investigate as much as you can, and if you don’t find anything, continue to monitor it until you know for sure.
