Absolutely the most descriptive and well documented video for Cleaning your Rheem Tankless Hot Water Tank Thank You Bill
Glad it was helpful! Thanks Linda!
Thanks for talking about the need for opening the bypass valve. Many other videos miss this part, and so folks are wasting their time just flushing the bypass valve, not the whole unit.
Great point!
Best tankless water heater flush video on the internet!!
Thanks so much, I really appreciate it!

Awesome video. I checked out other Rheem maintenance videos but this was the most detailed by far. Only minor thing is that you don't show turning off the water when cleaning the filter. You do turn it back on after cleaning the filter so turn off the water before cleaning the filter for the viewers out there.
Thanks for the tips!
I love the Sparky Channel, so efficient, gotta respect that. I'm going to tackle this project today.
Thanks so much!
Another great video on flushing the tankless water heater! I saved your old video but couldn't find it. Now I see you have a new video up. Thanks again!
No problem, thanks!
Great video, I truly appreciate you taking the time to show what you did, and explained everything very thoroughly!
You're very welcome!
Well done. Made tankless cleaning clearer!
Great to hear! Thanks!
Thanks Bill. One tip is you can use washing machine hoses, they have the same thread as garden hose and both ends are female
Great tip! Be sure that they have brass ends though. Otherwise the vinegar will destroy them.
@@SparkyChannel Great point. Maybe we will install of these in future.
@@jamescc2010 If yours don't have brass now, wait till these ends going bad then you can replace with the brass ones.
Bill, I have tried every power down configuration there is including the one in your video and I just cannot get water to flow out of the hot water side from the pump. I can open the relief and it will flow, but not through the HE out of the hot water side. My Rheem is a 2019/2020 model. Thanks.
Good demonstration Sparky.
Thanks Gary!
Thanks Bill for uploading this very informational video yet again.
Thanks Atif!
Thank you for this video. Every year i come back to review before I fkush my tankless.
You're very welcome. Thanks!
Vinegar from Smart and Final! I use the same stuff in my outdoor fountain. I use that because the birds will drink the diluted solution but it keeps the mold and junk out of the fountain.
Yep, Smart and Final. LOL! Have a great day!
Vinegar is also useful for poultry & their gut health.
Thanks for the video!
I have a problem on my rinnai condensing water heater. I flushed it today and after doing it, even when heater is not running, there is a steady flow of water from condensing pipe. What to do to fix it. Thanks!
I like those OSHA approved safety sandals ... Lol ... Good vid Wild Bill ...
LOL! You weren't supposed to see them. :) Thanks Eddy!
@@SparkyChannel were those steel toe bill? You know how to check right? You take a 28 oz. Framing hammer new of course and smack your toe, if you scream they're not steel toe .
Can you reuse the vinegar for your next flushing?
No, it gets dirty. You can pour it down a drain and it will help clear out the drain.
Much appreciated, thanks Sparky!
My pleasure, thanks!
Can share benefits of tankless vs regular water heater regarding energy saving, initial cost, and maintenance?
Great job again sparky! but answer the question everyone is asking - how soon until you've completed the flux capacitor?
LOL! Working on it! :)
@Sparky Channel. Thanks Bill. Learned something I can keep in mind when I have a tankless hot water heater installed.
Hope you and your family stay safe and healthy.
Sounds good, thanks!
Hey Sparky,
I purchased a used Rinnai tankless heater.
It is not yet installed.
I want to flush it in order to check whether I should keep it. (I can return it.)
How can ensure the bypass valve is fully open BEFORE installing it?
Without the unit installed, can I plug the heater in and turn down the temp to 98 on the unit (I don't have a remote.), and then turn the heater off in order to fully open the bypass valve?
Thank you,
Thank you for sharing!! How often do you recommend flushing your tankless hot water heater??
Just like a tank unit, tankless water heaters need to be flushed once per year. Homeowners with hard water should consider flushing and cleaning the unit even more frequently, perhaps every six to nine months because of the excess amounts of magnesium and calcium found in hard water supplies.
1. The entire process can take up to an hour or more to complete.
2. Turn OFF the gas and both the hot at cold water supply to the
tankless water heater. The gas must remain OFF during the
flushing process.
3. To properly flush the heater the electronic bypass valve inside
the heater must be closed. Follow these steps to do this: At
the remote control, turn OFF the power and wait 10 seconds.
Turn ON the power at the remote control, wait 10 seconds,
and disconnect the water heater from the electrical source.
Hi Bill! I love all your videos!! Thank you. I have Rinnai Tankless Water Heater. in this video, you mentioned that if you have a Rinnai set up the temp to 98 degrees. Question: Do I need to set up 98 degrees AND turn the hot water on first before I unplug the power from the Unit? could you please clarify? Thank you Bill!! :)
For Rinnai:
1. Turn off the power source for your tankless water heater.
Shut off the main gas or turn off the circuit breaker for electrical devices.
2. Close (turn off) the three water valves attached to your tankless water heater.
This prevents cold water from flowing into the water heater and hot water from coming out during the cleaning process.
The water valves consist of a cold water valve (colored blue), a hot water valve (colored red) and a main valve that runs the water into your home.
3. Remove the purge port valve caps slowly from the purge valves located on each of the cold and hot water valves.
The purge valves have small handles that resemble the letter "T."
This procedure is done to relieve any pressure that has built inside the valves and will prevent excess hot water from shooting out during the cleaning process.
There may be pressure when removing the purge port valve caps, so it’s vital to confirm the hot water valve is completely shut off for your safety.
Handle each cap carefully so the rubber sealing discs stay in place. These are needed for your valves to function properly.
4. Attach hosing lines to each of the three valves.
If the manufacturer of your tankless water heater did not provide hosing lines, they are available at any home repair store that sells water heaters. The hosing lines must be long enough to reach between the water heater and a bucket.
Consult the manual provided by the tankless water heater manufacturer or contact the manufacturer directly for exact instructions regarding this procedure.
In some cases, this procedure may require you to use a sump pump and connect hoses to discharge and flush water from the tankless water heater cold and hot water valves.
5. Open the purge port valves by twisting them perpendicular to the position of the cold and hot valves.
6. Use 4 gallons (15.1 liters) of undiluted white vinegar to clean your tankless water heater. Never use chemical solutions of any kind.
Since your home’s drinking and bathing water mostly likely flows through your tankless water heater, using chemical cleaning solutions could be extremely harmful to your health.
7. Follow the instructions included in your manufacturer’s manual to perform the flushing and draining procedure.
This procedure may take up to 45 minutes.
8. Once the flushing process is complete, close the purge port valves by twisting the T-shaped handles.
9. Disconnect and remove the hosing lines from each valve.
10. Replace the purge port valve caps onto the purge valves.
Tighten the caps completely and firmly. However, take care not to over-tighten or break the rubber sealing discs inside the caps.
11. Refer to the manufacturer's manual for exact instructions on how to safely restart your water heater.
This may require you to rotate and open the cold and hot water valves so they are parallel to the position of the main valve.
12. Choose a sink tap inside and turn on the hot water slowly to allow the air to pass through the pipe.
Continue to run the water until it runs steadily without air escaping (you may recognize this by a slight sputtering sound). .
It may take to 2 or 3 minutes for all of the air pockets to escape.
Draining the rinse water into a 5 gallon bucket for 5 minutes? Fills up pretty fast.
I attached the water hose and sent it to the street
@Sparky Channel Great content! I have to redo my flush now. :-) When I did mine I had a filter on the pump output and sock on the hose from the heater. Any hints for a Bosch? I have the model that generates a spark from the water flow (using a spinner?) so no electrical connection. Is it OK to heat the solution to ensure it gets to the boiler?
There is no need to heat the solution. I would just go by the Bosch manual. Bosch is usually very good with their instructions.
Shouldn't you open the maintenance valve AFTER you open the maintenance cap? No water would be splashing everywhere.
Good point.
My tankless water heater does not work sometimes and needs the hvac system to be turned on. What could be the problem?
Love the Sparkman! I learn so much from him always! Please subscribe and thumbs up since that shares it with many others.
Thanks so much Joe!
Do you have a link for the filter you have on your cold water input? I don't see one on my tankless and I 'd like to add this. Thanks!
No, sorry. You'd have to call your manufacturer for that part.
Thanks so much for your help,god bleas you.
My pleasure, thanks!
did the opposite, I left the shut off valves open and had the service valves closed at the hot and cold water lines at service valves. What damage did I do if any?
I don't think that would cause a problem. How did it turn out?
I fixed it and no issues.
Thank you for this instructional!!! It was really helpful.
Thanks Johnny!
Wow! Great video! Is this heater at your own home?
Yes, it is! Thanks!
why not run the water to get rid of the air bubbles first before turning the water heater back on
We’re is your old video showing the installation of this unit? I tried searching but could not find it
I'll look for it on my hard drive, thanks!
Great job!
Thanks!
How frequently should this be done?
Just like a tank unit, tankless water heaters need to be flushed once per year. Homeowners with hard water should consider flushing and cleaning the unit even more frequently, perhaps every six to nine months because of the excess amounts of magnesium and calcium found in hard water supplies.
When you turn the gas back on, will it light on it’s own?
Yes, when a hot water faucet is turned on.
Sparky Channel propane also correct? Thanks so much!
@@beckydale Yes, running hot water will turn on the tankless water heater.
You should increase the temperature of the water heater up to between 55 and 60°C (131 and 140°F) to avoid pathogens like legionella in the hot water system. Legionellas favourite temperature window for reproduction is between 30 and 45°C (86 and 113°F).
OK, thanks!
I guess that goes for regular water heater too. The temp I have has high, medium, low. Maybe I need infrared thermometer to measure.
Where can you get a submersible pump?

Great video . Now i must use the facilities with all that water running. Lol 👍
LOL! Good one!
Am not sure if I did something wrong , i got code 11 on my rennai
Rinnai error code 11 is an indication that there is no ignition in, or no gas supply to your hot water system. You can try the following to fix the problem: Check your hot water system for any visible damage or loose parts. Locate your gas supply and ensure it is turned on.
Awesome
Thanks!
Big contention about needing to make sure the bypass valve is closed...no one really talks about it.
So true, thanks!
Awesome
Thanks!
