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!
Why are you heating hot 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?
What is the size of the pump that you are using?
@@jazihbaebeshaki4370 He used a Utilitech 1/6 HP Submersible Utility Pump
After putting this job off for months I turned off the TV, got my ass off the couch and did this. THX
Time to do it again. GO
This is me today lol...start the clock.
It’s so damn hard to get motivated, isn’t it?
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😃
I do not even have a tankless hot water heater - and I still clicked the LIKE button.
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.
Pro tip very much appreciated! Didn’t think of that.
Yeah, I like that.
Lol or just open up the overpressure valve and let it all go out that way.
@@rednkfn That too.
Exactly what I thought the first time I watched this video.
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!
This was incredibly helpful!! Thank you - worked perfectly, cost me about $75 total....I got a quote from a plumber for $540! ...thanks again!
Great how too! I put an old nylon stocking on my return to help trap the lime and other solid junk. Plus it fun to watch it fill up with and see how nasty it was.
You get better results with the tankless flush solutions. Ask your manufacturer and try it. The difference is astounding
Bought the equipment, followed your directions carefully ... mission accomplished! Thank you
Thus was insanely helpful, clear, to the point. Well done
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.
Thank you! I bought a kit off Amazon and your video made it incredibly easy.
Clear, straightforward, and useful. Thanks!
My wife has been after me to get this done. This video put me over the edge ordering stuff to get it done!
You definitely want to do it,, glad the video helped!
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!
Great video. Good lighting, good explanation, and I like the easy steps for when the job is finished.
This was an exact replacement for the old one that lasted about 10 years. ruclips.net/user/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).
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.
@@5ghostshadow i plan on doing the same thing. REmoving my old tank from a central closet so i can remodel two bathrooms
Unfortunately, they just don’t build appliances to last anymore. I think Toyota needs to get into the appliance business!
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.
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.
Very well done! Thank you for the intuitive approach to this :)
Best video out of four I have watched. Plumber told me a transfer pump is best to use.
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.
Excellent step by step process! Perfect! Thank you!!
Thank you so much.. I was able to follow your clean instructions to do this today.
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...
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!
This is an excellent quality video, and professionally done. Thank you!
You're very welcome!
This video is well made. Very easy to understand.
Many thanks for your video. Very very helpful. Much success with your business
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.
Very clear explanation.
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 did this as well!!
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.
Doing this now and so far so good. My pre filter is in line though so I could not do it before. I'll do it at the end. Thanks.
Best tutorial ever, thank you sir!
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!!
You did a very good job explaining, good video. 👍
Glad it was helpful!
Excellent he was very thorough
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 RUclips who loves to maintain the yard/house...so your content is awesome! :)
Very kind of you to say, so glad the videos have been helpful too. Thanks again
@@SilverCymbal Once things return to normal, hope to meet you someday at a concert! :)
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.
great video thank you for helping us out
Very Very Good job , mate .
It's a new helpful video everytime! Keep up the awesome videos
Thank you so much
this is genius! never thought about it.

Another money-saving video thank you
Happy to help!
Good vid! Great job!
great simple explanation
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.
Very good video going to try it. Keep up with the great videos you produce.
Thank you very much for the nice words!
Great video!
Awesome video, I was looking for this thanks.

That is so nice of you to say, glad you like the videos.
Great video.
Been wanting to do this I have the unit top floor in my walk in closet behind the wall
Of bathroom also have a steam unit thank you
Great video, hook up hoses first as said in other comments but very helpful.
Thanks for sharing this
Another excellent video.
I appreciate that
this was perfect. i just cleaned out my system using your video step by step. although i couldn’t the filter. have you seen some without one?
Omg Thank you!! I have a tankless water heater and spending over 368$ to get it flush. Guess what? I did it my self!!!
Great video. Thank you.
Glad you liked it!
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!
Well done, thanks!
Glad it was helpful!
Great video! 👍🏽
Thank you! 👍
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.
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.
You flush the pump with clean water when you're done with the water heater.
Its not hydrochloric acid,just ~4% vinegat,flush with water when done,good to go!
Thank you
Excellent video. I flushed my tankless water heater and found that after running the vinegar through the unit I emptied the bucket, filled it with fresh water and directed the hot water connected hose to my laundry tub. Then I turned on the pump and watched milky water run into the laundry tub. Filled the bucket up a couple more times and repeated the process. You'd be surprised how much residue is still in the lines after running the vinegar through the water heater.
Connect your hoses first after pulling off the caps. Put the hoses in the bucket and then open the valves. No need to spill any water.
Thanks a lot pal!
Excellent video and explanation- thank you! Any recommendations from anyone on a good 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!
@@BlakeAdamsCO Just what was mentioned here.
@@BlakeAdamsCO Sorry, forgot to mention...no internal circulation pump.
I like your video because it easy understands .🙏👏👏👏👍👍👍
Thank you so much!! You are the best!!!!!
You're welcome! Thank you so much
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.
Excellent video....I would just add that you should turn off the electricity at the breaker box.
The green color comes from the copper piping. Using vinegar in copper accelerates the corrosion process. Copper turns green when it corrodes
Is there any way to clean the tankless and avoid corrosion of the copper pipes? Or will the pipes just have to be replaced sooner?
Thank you you the best
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?
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.
How about the old fashion water heaters? Great video.
Wow thankyou
Very helpful and $$$savings video 😊.
Thanks.
I bought a used heater that needs to be flushed.
Can the heater be flushed before it is installed ?
If the heater is clogged, will this method open the flow?
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?
Found the Rennai filter screens online for $6. Just as easy to replace.
