How to Check Your Home's Water Pressure
ฝัง
- เผยแพร่เมื่อ 25 ต.ค. 2024
- Test your house water pressure & find out what pressure ranges are normal. Check static water pressure and measure thermal expansion pressure.
If the municipal water pressure is too high, it can damage a home water supply system. High water pressure can damage pipes, cause leaks and cause water hammers.
Regularly measuring the water pressure in your home can determine if your water pressure regulator is working properly. It can also insure that the thermal expansion tank or thermal bypass on a water pressure reducing valve is working. If a thermal expansion tank or thermal bypass is on properly functioning, a hot water heater can explode.

Well done! Your explanation was clear, concise, and consumable! (You must be an engineer! I recognize how well organized this was!)
Wonderful video!! This allowed me to prove that my home's water pressure regulator went bad. I had a new hot water heater tank installed and it was leaking from the T/P overflow valve, even after an expansion tank was installed. The newer tank's T/P valve's pressure threshold was much lower than the original tank's according the the plumber. This video showed the exact test my plumber ran, and he was able to install a new regulator that same day. All has been perfect ever since with no leaking from the new hot water tank overflow valve. I just hope the over pressurized plumbing doesn't cause me problems down the road. I already did have some pinhole leaks a year ago that needed addressed. I will buy my own pressure gauge now, since this is as easy as checking tire pressure. I will test annually or more frequently to monitor the state of the new regulator. The old one looked to be 15-20 years old.
great stuff. All these years I never did this. Now that this EPA well serving about 34 houses where I live is chronically low flowing I am going to do this and present the results to our Water Company. Thanks for doing this!!
You are welcome. Best wishes for resolving the low flowing water.
Absolutely clear and professionally presented. Perfectly done, thank you!!
You are welcome!
Kept getting leaks in my house. I bought the house 15 years old, so I just figured it was older fittings or glue failure. After about 4 leaks in 12 months, I knew something was up. Guage on water faucet pegged out at 125 psi. Fix one leak and the pressure moved on to the next weakest link. Wish I would have installed mine more accessible than 2 foot in the ground a foot from the concrete slab!! Like they say... Hind sight is 20/20.
I tested the water using the gauge.
The red shoots up to 100 psi and the black is at 50 psi.
I tested it 4x and all the same result.
I do have a expansion tank but that’s after the PRV, as the PRV is installed outside
Really informative video! I liked the tip to check it once a year and how thermal expansion could affect your homes water pressure!
Thanks for the compliments!
Very nice presentation. Thank you for your time putting that together.
You are welcome, Daniel. I've been having fun making the videos and being able to help people solve problems.
Thanks for commenting, it's always good to hear that the video has been helpful.

@@acilaja6515 Translation from Indonesian: Be careful not to put too much pressure on the pipe, the pipe will explode.
Excellent video. Exactly the information I was looking for. Thank you!
It's my pleasure to help. Have a great day!
How do you know when your water heater is in reheat mode?
Great info about the water heater affecting the test.
I have a few gauges that I haven't used (in the package) & none of them have a hose bib connection on them... just the small threads.

Really well done… thanks
You are welcome, Mike.
I have a damaged pressure relief tank, and have its replacement; I just need to determine the water pressure so I can inflate/deflate the bladder in the relief tank to match it. I live in a condo and I don't have a hose bibb. The tip about using the washer supply was very useful to me because I agree that possible HWH sediment would compromise the guage.
As with many things there is some debate about that question. Most people recommend matching the tank pressure with the water pressure. If the installation instructions don't offer any guidance you could contact the manufactuer's tech support for their recommendation.
I found out the water is coming to my house at 100 psi, no wonder I have had problems with my washing machine solenoid valve, fixtures and others. I just installed a regulator and set it to 50 psi.
Connecting the gauge to the water heater is not the preferred location. There is often sediment on the bottom of the tank that could get into the gauge.
Thank you
You're welcome, Christopher.
nice and helpful video
Thanks for the compliment, Eduardo. Have a great day.
Very helpful, Thank you.
You are welcome.
Thank you so much
You are welcome, it's my pleasure to help.
That red tab for the top reading is super sensitive and I keep finding that is shoots all the way past an accurate number just by the force. My reading is at 60 psi. I left over night and saw the red line at 82. Is the 82 from thermal expansion? I checked again later but that red tab shot all the way past the numbers due to sensitivity.
Most likely, an expansion tank will solve that problem
This is very hard... Manometers' connection are very confusing... I need to know if my water pressure if above 4bar but it's an impossible job at this point.
Great helpful video . Which Wilkins pressure regulator do u recommend . Should I put two in just in case as lot of stuff I have gotten in past comes from China and fails . Have you heard of Equalibar? Do u need to get omw with babe so I.can read ? Thanks so much ahead for your help!.
I can't recommend the correct pressure regulator for your situation, there are many models. If you have an existing one and you know it's the correct model, replace it with the same one. Installing two in series will likely cause problems. Never heard of Equalibar.
My pressure starts at 20 and after a few hours goes up to 85...which number is accurate. I attach the gauge on to the faucet that is located in the garage
20lbs of pressure is on the low side. The high number could be caused by thermal expansion when the water heater turns on. If you have a pressure reducing valve (PRV), it could be failing.
House water pressure should be set at 65 psi. If you’re not receiving enough water to properly shower then you could bump it up to 75 psi. I remove all water savers from my showerhead so that I could get clean faster and actually save more water. When you have long hair it takes forever to clean your hair with minimal water. Do you want a good shower or not?
Thank you it’s a good video.
My valve measures at 55psi but overnight, it shot up to 85psi. It's back down to 55. Is that alright? My pressure reducing valve has an upper limit of 75. Is this due to the hot water heater's thermal expansion and should I be concerned?
I explain how a water system/PRV/water heater works in this video. You might find it helpful. th-cam.com/video/E8VJxb_eUQI/w-d-xo.htmlsi=dOIcnCFBTdNcfbHf
Thank you! I watched the video. I have a closed system but what's still not clear to me is if my water pressure gauged jumped up overnight and went back down, does that mean I have a problem? I checked my expansion tank and it is properly pressurized.
If no water flowed, then it's likely your water heater kicked on overnight and caused an increase in pressure. The bladders in those expansion tanks can fail. Maybe that's what is going on? Make the water heater turn on and watch the gauge to see what happens.
I double checked my expansion tank. This time, I turned off the water and drained some hot. What do you know, the pressure on the expansion tank was near zero! I decided to reinflate it back to 55psi and overnight it seems to be holding. I probably should replace it but for now, it appears to be holding air.
There's a bladder in the tank, it likely leaking. th-cam.com/video/Q-iJ6jBkG1Q/w-d-xo.htmlsi=v99qim8Z8OhZV29P
what is open system and how the thermal bypass works?
Hi Mirian, I replied yesterday, but my reply is missing from the comments... let's try again. I think one of my other videos will answer your questions. Here's a link to Troubleshoot a Leaking Water Pressure Relief Valve: th-cam.com/video/E8VJxb_eUQI/w-d-xo.html
I have a water pressure of 100 psi when i use the water it drop to 65 and if i close the water it goes up to 100 in 5 sec if i regulate it it goes up or down but it i close the water it goes up to 100 should i change it or it is the water heater
Do you have a pressure reducing valve?
What if my water pressure starts out at 45psi and then gradually goes up to 80plus psi within 2 minutes? Which number is my actual water pressure?
It sounds like your water heater may have turned on, most likely the normal pressure is 45psi. I have a video that explains how a water heater increases pressure: th-cam.com/video/E8VJxb_eUQI/w-d-xo.html
Know How Now it's weird because I already turned my water heater to vacation mode like you said. Any other ideas?
Did you try the test more than one time? If yes, does the pressure start at 45 & rise to 80 plus every time? Where did you connect the gauge? Maybe the gauge is faulty or has dirt in it. You also may try leaving it connected for a couple of days and periodically check on it. If the water heater has recently fired, if you open a faucet it will release the excess pressure caused by the heated water.
If you have a regulator or back flow preventer in the main line, you must install a thermal expansion tank near the water heater.
A failing pressure regulator (seat), will account for a slow rise in pressure.
Thanks Know How!! Plumb on sister.
You are welcome, Chuck. Have a great day.
my pressure is 30 and my town says that's all they need to provide. I find this hard to believe
Sounds right actually, that's all they are required to do. Imagine your pressure was too high, they wouldn't fix that either and everything would be leaking so...
But hey if it's really a bother you can hire a plumber to put in a booster pump I'm sure they are only a few grand installed.
All this is under ground
Just call a plumber and they come for free
👌🙏🙏😎
We got ours cranked up to 120psi. Make it easy to wash cars🌝🤔😁

Regulation suck
Yeah, sometimes they are dumb and sometimes they are a good thing.
The word is SPIGOT not SPIKIT.
It's my pleasure to upload the video to help you, Phyl. I am offended that in return all you can do is mock my accent.
I'd love to talk to your mom and hear her accent. I enjoy hearing different accents.
