When doing what you are doing... tie a women's stocking over the end of the red hose... it will capture the calcium particles... if you do not use a stocking .... the calcium particles will go back into the pump and back into the filter screen... thus cleaning the filter screen again....p.s..use cooking oil on the filter screen o ring... it will prolong life of the o ring and help seal it better...p.s.s one time I was in a jam... I used my sock! And if you want.. add a anti scale filter on the incoming cold water side... change filter every 3 months... and never buy vinegar again! Antiscale filter is easier, faster,, and inexpensive p.s.s.s. antiscale filters will also remove alge and slime in the water!
Isn’t there a part in the tubing where the hot water is leaving the heater and about to go into house that needs to be cleaned? I think that junction in tubing may be clogged since I have very hard water where I live and my hot water pressure suffers immensely. Any info on that?
Also... tankless units typically have an air intake filter, which should be disassembled and cleaned as well. This is located on top of the unit, between where the air intake pipe connects to the unit itself. It acts as a catch-all for any dust ,debris, or buggies that may work their way in from the outside. Great video! Thank you!
Be a great idea to flush the system after your done too with clean water. Disconnect the intake hose and close the valve off and then turn on the water intake valve while the hot water side is open with the hose into a drain. Let it drain for 2 min to flush out the vinegar and any other debris you may have left. Also, I've found adding a sock with a rubber band on the discharge hose to be a great filter so you're not running sediment back through the vinegar flush.
Thank you! Was wondering about flushing out any leftover vinegar...needed this tip on using the normal water flow and leaving the hot side hose outlet still in bucket😃
Pro tip: Hook your hoses to the valves before opening...then you can just drain the heater's leftover water directly in the bucket instead of water going everywhere.
This was an exact replacement for the old one that lasted about 10 years. th-cam.com/users/postUgkx7yWIKcrbA9KMHkGSfcgxW2lsjHT6B8Sh The top of my mitigation tube by my roofline was just a 90 elbow which allowed too much debris to fall down into the fan, eventually ruining it. Without this issue, I bet it would have kept running another 10 years. When I replaced this fan, I added an extra elbow joint so the top tube now it does a 180, which should solve that problem. The radon guys around here wanted to charge me a $300 diagnostic fee, then parts/labor (probably close to $600 total). I installed this all by myself in about an hour for the cost of the fan; it would probably be even easier/faster with two people. FYI the manufacturer's warranty greatly differs depending on whether you install it yourself (1 yr warranty) or have a licensed installer do it (10 yrs).
I very much appreciate your tutorial on flushing a tankless, water heater. Just a note: I took your advice and, after an hour of flushing, I double checked the small filter, and, it had more CRUD on it than the first inspection did (almost plugged up). I would hope you would prioritize this step as it is so easy to perform. Thanks again for the concise video. Take care...
What you said about calling a plumbing company is true the cost of doing this maintenance every year is good for you water heater keeps ur unit running good with out have any problems with it. Good video.
very clear lecture voice. good professional teaching A to Z. fantastic easy way step by step even can 5 yrs old boy can follow to do it himself. thank you so much.
Thanks Silver Cymbal for all your content, from yard stuff to this! Didn't realize this was something I needed to do...ordered the stupplies, flushed the tankless hot water heater, and my white vinegar turned blue too! :) I'm a pianist on TH-cam who loves to maintain the yard/house...so your content is awesome! :)
Best quality How-To video I have seen on flushing and cleaning a tankless hot water heater. Incidentally, one of my tankless water heaters is the same make and model in this video.
Great video! I would absolutely check the cold side filter a second time after the vinegar circulation - mine was clean on pre check and had a bunch of sediment after.
It might help to filter out the scale particles in the red hose ( returning the cleaning solution) before it goes into the bucket. The faucet used for the final rinse may get a restricted strainer if big particles are still present. Thanks for the technique you shared.
That's where I'm heading now (married to a nagger! shhhh) so I want to do it before the real nagging --oops, I mean "urging" starts. Thanks for the extra motivation!
I plan on owning a home soon and I've loved every video you posted. Thank you for your thoughtful, well crafted, and easy to follow series of videos. Thank you.
Awesome! So nice of you to say. I do so much myself and yes it takes me a little time but year after year you really can save a fortune on so many jobs.
I regret not getting a tankless water heater when I needed a replacement but plan on getting one next time. Thanks for this video, great info. I'm a bit amazed though that the vinegar doesn't destroy the pump.
I just flushed my Navien NPE-240A using a regular 1/2 HP pump instead of a sump pump and it worked like a charm. It floods periodically where I live so I am well equipped with pumps, so I used what I had. Thank you!
Does your Navien have a recirculation pump and storage unit in the heater? If so, did you have to do anything with that specifically or just what's mentioned here? Thanks!
I followed this video STEP BY STEP. Thank you so very much for such clear and concise instructions. My only issue was the pre-filter would not come out. I unscrewed it, was able to get the washer off, but the filter itself would not come out. Oh well? But for the rest, feeling very good about my tankless! THANK YOU!
Mine failed in 3. I did all the maintainence. First the fan went, then the burner went. They were covered under the warranty and repaired. Once the board went and it wasn't covered under warranty I went back to the tank. I wanted to love it. Maybe I had a lemon, but issues from others didn't boost my confidence. Ill wait a few more years as popularity continues to grow.
Tankless heaters are not perfect and many had major issues in the early years. Keep an eye out for a new videos talking about the differences but as you have found they aren't perfect for everyone and they have a lot of technology in there,
@@SilverCymbal it was a sad loss because our utilities are in a closet. Taking the tank out and installing a tankless elsewhere afforded us much needed pantry space in that closet. I wasn't happy to go back to the tank lol.
@@SilverCymbal Our Rinnai tankless water heater is 8 years old and no problems until this year. I’ve never done any maintenance but noticed a decrease in pressure, then I found this. I’m doing the maintenance. Don’t give up on tankless. It saves me about $20 a month in electricity and I never run out of hot water even when guests stay over.
Definitely recommend doing a fresh water flush with the bucket/pump right after for a few to get the majority of that residual vinegar you mentioned. Only takes a few minutes and prevents that residual vinegar from entering your fresh water piping.
While the vinegar won't hurt anything, I like to flush it out. Just remove the pump hose to the cold side and cap it. Then slowly turn on the cold water which will flow thru the unit and out the hot hose into the bucket. Done.
I would be more concerned with leaving vinegar in the pump between uses. For that reason, I agree that you should flush with fresh water before storing the pump.
Great video I had a new IBC boiler tankless hot water heater installed and after a year I had it flushed and it cost me $250.00 so after that I decided to buy all the stuff I need to flush it out and do it myself looks very simple to do.
excelente explicacion, completa porque muestra realmente lo que hay que hacer y sin egos de mostrar a una persona, la mejor que he visto de todos los plomeros que circulan por las redes... EXCELENTE!! GRACIAS!!
Doing this right now! My unit is in the attic! Such a struggle lol. Luckly, I have a drain pan underneath the unit that goes outside. I think I can use that to dump the nasty water??, instead of carrying the bucket down the stairs from the attic The blue and red values that you need to close (not the maintenance ones) was a struggle to close. I had to unscrew it and use pliers to turn the valves.
Very informative and well demonstrated!!! I don’t have a tankless because of the stories regarding constant maintenance. What is the manufacturer or yours and are you still happy with yours or would you now purchase a different model/manufacturer? The plumber that installed the one in the video definitely had maintenance in mind and made it easy to access important connections/valves!
This one is actually at my friends house who need it to be cleaned, he absolutely loves it & it works great for a big house with kids. Very happy with his purchase. This model is a State brand water heater, but the real brand is Takagi. Seems to be a great unit.
Thank you for your video. I've been negligent in maintaining my tankless water heater and I just purchased and installed the bypass valves for circulating the vinegar/cleaning agent. The initial installer hooked up the heater without bypass valves ($75 to $80 at Home Depot). My tankless water heater recently started providing a hot shower for approximately ten minutes then the water got cold. I'm hoping this fixes the problem.
@@agoogleuser6902 I try to do this once a year (before symptoms arise) ...but.....the last few days my water isn't getting as hot and I KNOW that I'm overdue. Flushing will fix that. Good luck with yours!!
I am having the same problem, all the sudden the water gets cold while in the shower. Just had it cleaned, and now it takes FOREVER for the water to get hot!
Almost ended up getting one of these. Nice video. Maybe you could do a video on cleaning mesh water filters for irrigation system. The cost is beginning to add up.
Water softener's remove most of the minerals and calcium that make water hard, I would still flush maybe every 5 years for the hell of it. But really not necessary
The frequency of the cleaning depends on the water in the area you live in. I just picked up a gas water heater that probably hasn't been cleaned in 20 years. I turned it upside down and let it soak in vinegar overnight.
Thanks good video, I do this every year. Why not just hook the hoses up from the beginning when you're draining the system and then it'll all go in the bucket instead of making a mess?
I did exactly what you said it didn't work for me. After many trips to the hardware store, I was finally able to get the correct hoses/adapters, etc. I hooked everything, turned all the levers like you said. Put the sump pump in the bottom of the 5 gallon(probably a little more) bucket and turned on the pump. It worked fine but nothing, NOTHING came out of the red flushing valve. I let it run for a little over an hour and when I came back the vinegar was as clear as the day I bought it. I felt both hoses and the one hooked up to the pump was working but the other, nothing...No vibrating, shaking...nothing..it was as if it was dead on that side. I don't know what to do now. I'm using regular garden hoses, not washing machine hoses. I even turned the knob that controls the water and nothing but when I took the hose off, there was plenty of water coming out until I closed it again. Why is this not working for me? Oh one more thing...I took the filter out and it was CLEAN as a whistle and this house is 5 yrs old and has never had this tankless water heater cleaned.
Great video! Would an in-line filter coming off the pump into the supply side not be beneficial so you’re not pumping scale back into the water heater?
I wanted to put one in my house that was built in 1947. There was just no way to vent it without spending a small fortune. I Had to go with a tank instead. A tank will last way longer if you change the anode rod every couple years. It wasn't my first choice but we got a nice tank thanks to that stimulus check.
@@Gitarzan66 they make electric ones, depending on the size, they can eat up electricity while in use. I have eco smart tankless heaters, very effective and need no ventilation
very nice video. good explanation of each step and actually, I am more confident now to do the descaling of my Rinnai unit myself. Thank you.. will be using 3 gallons white vinegar and 3 capfuls of CLR.
Great video. Thanks. I use citric acid to clean my coffee maker. I buy the powder in bulk. Turns out it’s the same stuff you can buy premixed that’s very costly! We were told by the manufacturer that vinegar doesn’t do as good of a job. What are your thoughts in using citric acid instead for the water heater?
Citric acid is recommended by the manufacturers of coffee makers because it does not damage the seals. Especially the seals in the pumps are prone to getting hard and fail if vinegar is applied repeatedly. Another problem are coffee residues. They are sometimes impossible to remove, but they will take on the taste of vinegar. Definitely doesn't improve the taste of your coffee. In contrast citric acid has much less of a taste. After flushing you will definitely not taste it.
Would it make more sense to to connect the washer hoses before draining the water heater? That way you can direct the water into the bucket rather than trying to catch it.
My plumber did not recommend installing isolation valves seven years ago. After having water runs cold mid-shower getting more frequently in the last one year, I’d decided to do it today. No pump, no isolation valves, i managed to finish it within two hours, for about two dollars, and never hat cold shower again! Simply turn off gas supply, turn off and unplug electric power supply, run hot water taps dry, and you are ready. You need two flexible shower hose with suitable threaded ends (usually 20mm), a large plastic syringe of 100-200ml ( if you don’t have electric water pump or electric drill-driven water pump), bucket, vinegar (1-2L will do). Usually inlet and outlet hose are of rigid copper tubing. Now it’s the fun part; To seperate copper hoses, you’ll first loosen their 20mm nuts, both inlet copper tube and outlet copper tube. Next, remove copper tubes sideways by lift the heater upwards for a few millimeters by loosening its wall mounting screws (loosen a few turns ONLY! Not removing them). Now, fasten shower hoses onto inlet and outlet. Outlet hose into bucket of vinegar (1-2L will do). (PROCEDURE WITHOUT PUMP) Inlet hose’ open end placed higher up, about the same height as top of heater. Use syringe to draw vinegar from bucket, pump vinegar into inlet hose’ open end. Repeat for a total of 100 repetitions ( that’s about 10L of vinegar flow, from the same amount of vinegar in bucket, recycled), this can be done in an hour or two, with a helper preferably. You’ll see vinegar turns to green tinted color. Then purge all vinegar (properly). After that, its about flushing out vinegar residue with clean tap water. Find ways to inject clean tap water through inlet hose (garden hose will do), for a few buckets full of clean water out through outlet hose. Then its time to reinstall everything back. Remove shower hoses, both inlet and outlet. Reinstall copper tubes, both inlet and outlet. Gradually turns water back on, check for leaks at both inlet and outlet. Wipe clean everything. Turn gas back on. Dry your hands. Plug in and turn electric power back on. Check for hot water at taps everywhere in the house for continuous flow of hot water, and you’re good now.
I might add if your pump is running too hot set your five gal bucket into a larger container filled with cold water , the cold water will draw the heat out of the bucket
Hi. Great video, but a couple of questions. At 4:47, you show turning on the hot side of a faucet before opening the water supplies on the unit. What purpose does running the sink serve? And... should you leave the sink running on the hot side while you open the water supplies on the unit? Thanks!
Mine is about 17 years old water heater never thought about this but in case I have to replace it which I think is coming up which is better tankless or the tank one Sorry I am very naive in this matter Should I even try this cleaning now or is it too late
FYI I just checked the bottle of my 30% vinegar. It says it can damage the finish on some metals, so probably best to dilute it. For 30%, 1 part vinegar to 4 parts water will take it down to 6%.

The blue and red values that you need to close (not the maintenance ones) was a struggle to close. I had to unscrew it and use pliers to turn the valves.
The green color comes from the copper piping. Using vinegar in copper accelerates the corrosion process. Copper turns green when it corrodes

I did exactly what you said it didn't work for me. After many trips to the hardware store, I was finally able to get the correct hoses/adapters, etc. I hooked everything, turned all the levers like you said. Put the sump pump in the bottom of the 5 gallon(probably a little more) bucket and turned on the pump. It worked fine but nothing, NOTHING came out of the red flushing valve. I let it run for a little over an hour and when I came back the vinegar was as clear as the day I bought it. I felt both hoses and the one hooked up to the pump was working but the other, nothing...No vibrating, shaking...nothing..it was as if it was dead on that side. I don't know what to do now. I'm using regular garden hoses, not washing machine hoses. I even turned the knob that controls the water and nothing but when I took the hose off, there was plenty of water coming out until I closed it again. Why is this not working for me? Oh one more thing...I took the filter out and it was CLEAN as a whistle and this house is 5 yrs old and has never had this tankless water heater cleaned.
I'm having same issue...did you ever figure this out?
@@petedeffner7002 same problem with my Rinaii. I’ve previously flushed it a few times with no issues, but this time is a no go.
I saw a comment elsewhere that said Rinaii units have an extra valve to open when doing the flushing.
Great video! Would an in-line filter coming off the pump into the supply side not be beneficial so you’re not pumping scale back into the water heater?
You should do a video on the pros and cons of a tank vs tankless water heater.
I am working on that one, they are perfect for a lot of situations but others get ripped off on what they think they get
I wanted to put one in my house that was built in 1947. There was just no way to vent it without spending a small fortune. I Had to go with a tank instead. A tank will last way longer if you change the anode rod every couple years. It wasn't my first choice but we got a nice tank thanks to that stimulus check.
@@Gitarzan66 they make electric ones, depending on the size, they can eat up electricity while in use.
I have eco smart tankless heaters, very effective and need no ventilation
very nice video. good explanation of each step and actually, I am more confident now to do the descaling of my Rinnai unit myself. Thank you.. will be using 3 gallons white vinegar and 3 capfuls of CLR.
Great video, hook up hoses first as said in other comments but very helpful.
Great video. Thanks. I use citric acid to clean my coffee maker. I buy the powder in bulk. Turns out it’s the same stuff you can buy premixed that’s very costly! We were told by the manufacturer that vinegar doesn’t do as good of a job. What are your thoughts in using citric acid instead for the water heater?
Citric acid is recommended by the manufacturers of coffee makers because it does not damage the seals. Especially the seals in the pumps are prone to getting hard and fail if vinegar is applied repeatedly. Another problem are coffee residues. They are sometimes impossible to remove, but they will take on the taste of vinegar. Definitely doesn't improve the taste of your coffee. In contrast citric acid has much less of a taste. After flushing you will definitely not taste it.
Found the Rennai filter screens online for $6. Just as easy to replace.
Make sure your hoses are cleared out after each job. We started a little business and learned the hard way. Now we clean out the hoses after each job.
Thank you. Well done.
I appreciate it, thank you
Would it make more sense to to connect the washer hoses before draining the water heater? That way you can direct the water into the bucket rather than trying to catch it.
That's fine to do, I like to see them open but whichever way works.
I connect them first, to minimize the mess.
What kind of submersible pump should we use so that the pressure is not too strong to break the tankless heater? Any specifications?
Awesome video, I was looking for this thanks.
Glad I could help
Thanks for this very informative vid! I just did this no problem!
Glad it helped!
Great video. I saw you own a house generator, I would love to see an oil change and maintenance video on that. Wishing you were my neighbor.
My plumber did not recommend installing isolation valves seven years ago.
After having water runs cold mid-shower getting more frequently in the last one year, I’d decided to do it today.
No pump, no isolation valves, i managed to finish it within two hours, for about two dollars, and never hat cold shower again!
Simply turn off gas supply, turn off and unplug electric power supply, run hot water taps dry, and you are ready.
You need two flexible shower hose with suitable threaded ends (usually 20mm), a large plastic syringe of 100-200ml ( if you don’t have electric water pump or electric drill-driven water pump), bucket, vinegar (1-2L will do).
Usually inlet and outlet hose are of rigid copper tubing.
Now it’s the fun part;
To seperate copper hoses, you’ll first loosen their 20mm nuts, both inlet copper tube and outlet copper tube.
Next, remove copper tubes sideways by lift the heater upwards for a few millimeters by loosening its wall mounting screws (loosen a few turns ONLY! Not removing them).
Now, fasten shower hoses onto inlet and outlet.
Outlet hose into bucket of vinegar (1-2L will do).
(PROCEDURE WITHOUT PUMP) Inlet hose’ open end placed higher up, about the same height as top of heater.
Use syringe to draw vinegar from bucket, pump vinegar into inlet hose’ open end. Repeat for a total of 100 repetitions ( that’s about 10L of vinegar flow, from the same amount of vinegar in bucket, recycled), this can be done in an hour or two, with a helper preferably.
You’ll see vinegar turns to green tinted color.
Then purge all vinegar (properly).
After that, its about flushing out vinegar residue with clean tap water.
Find ways to inject clean tap water through inlet hose (garden hose will do), for a few buckets full of clean water out through outlet hose.
Then its time to reinstall everything back.
Remove shower hoses, both inlet and outlet.
Reinstall copper tubes, both inlet and outlet.
Gradually turns water back on, check for leaks at both inlet and outlet.
Wipe clean everything.
Turn gas back on.
Dry your hands.
Plug in and turn electric power back on.
Check for hot water at taps everywhere in the house for continuous flow of hot water, and you’re good now.
Excellent he was very thorough
I might add if your pump is running too hot set your five gal bucket into a larger container filled with cold water , the cold water will draw the heat out of the bucket
Those bluish greenish color probably came from copper as oxide. Isn't it harmful to copper pipes
You are an awesome video maker great job thank you
That is so nice of you to say, glad you like the videos.
Another excellent video.
I appreciate that
Hi. Great video, but a couple of questions. At 4:47, you show turning on the hot side of a faucet before opening the water supplies on the unit. What purpose does running the sink serve? And... should you leave the sink running on the hot side while you open the water supplies on the unit? Thanks!
Mine is about 17 years old water heater never thought about this but in case I have to replace it which I think is coming up which is better tankless or the tank one Sorry I am very naive in this matter Should I even try this cleaning now or is it too late
thank you so much, looks so easy
I like your video because it easy understands .🙏👏👏👏👍👍👍
Super understanding video I’ll do if my self.
Great video!
Really good video. Thanks.
You're welcome! Thank you for the nice words
Can I use a stronger vinegar? 20%, 30%, 40%, 45% ?
FYI I just checked the bottle of my 30% vinegar. It says it can damage the finish on some metals, so probably best to dilute it. For 30%, 1 part vinegar to 4 parts water will take it down to 6%.
great simple explanation
Thank you! Well done sir!
Very informative. Thanks
Glad it was helpful!
great video thank you for helping us out
