This video is succinct, but had every necessary detail. My heater is 16 years old and had not ever been descaled. Our water is naturally soft, so I figured it could wait. There was a fair bit of gunk in there. Thanks for the instructions!
Bro you’re a pro! Such a great video man. I’m flushing tanks for the first time today after 3 years plumbing and this video got me through the first one flawlessly. Thanks! Now to do 8 more 😆
I will call a technician; however this video will let me know if he's doing the job like it's supposed to be done. Thanks so much for this excellent video. I'm sure that I will one day be confident enough to do this process myself.
Used this video last year to descale a Nortiz tankless and loved it. Was so simple and easy to follow. Searched and so happy I found again and SAVED it this time.. Thank you Mike Kinder for the step by step instructions
Have been searching for some time for the instructions to flush the water heater, this Video told me all I need to know to do the job of flushing my tankless Stiebel Eltron water heater. Thank you so much. After watching your video I feel confident enough to do the job.
Thanks for the video! Our Noritz is 10 years old, never been flushed, and started struggling to make hot water just as we're selling the house... now I can do this easy service on a weekend
@@jw3368 It went fine - and easy just as you detailed. I don't think we had much scale actually, and I was surprised how hot the hose got. But all done now
@@paulettepantoja7298 sorry just saw this. basically you know when the solution hits the heating element when the heater shows a error code number on the display and then i add the solution and it doesn't take long for it to flow through the system and I let it run for 45 minutes then remove pump and flush it out with house water for 8 mins or so.
Thank you! We just purchased a home with a Noritz running on propane. It was installed in 2008, without flush valves or isolation valves. I don’t think it has ever been flushed in the 12 years since. It is running on well water that is very hard. It is working, and does not have any error codes. I would like to install the factory isolation valves, with flush port, and a new relief valve. They have mixed in some galvanized fittings, and I want to repipe it all. Could you list the part numbers for the isolation valve kit, with relief valve and also a link or description of the flush pump that you use? I need to perform this maintenance ASAP. Will the water heater display an error code if it gets too much scale on the tubes? Thanks
Awesome video! Mine is firing up, making gurgling noises, cycles a few times, but the pilot keeps going out. Code 11 starts flashing. It’s 1 1/2 years old, but we have pretty hard water. Any other way to check/clean the filter without draining it? Its also brutal cold, 14 degrees in Tennessee!
I wonder what it looks like inside heater as we never descaled it since we had it installed over ten years ago. There was a little gritty grey coloured debris captured by the filter but not to an extent blocking inflow.
Thank you greatly for a nice video. My tankless system has two identical Noritz units connected, with one as a spare. Would really appreciate your explanation about descaling the entire system with both units.
This is the best vid i have seen for sure. The only thing that this video and all others leave out is how powerful of a pump to use. I was looking at a 1/6 hp on sale today. Is that ideal?
I have never descaled my noritz tankless water heater in 15 yrs. Anothe unit I have never descaled also in 12 years. Is it too late to try or would my efforts now produce good results? Also how often do I need to do the descaling?
I have a Noritz. I notice the hot water shuts off complietely then 3 or 4 minutes later it starts up again and gets hot. Could that be the until. The other rooms do not are ok. Can you tell me what is causing this?
Ok , I have a noritz 14 years, just started Not working correctly, it will light and burn for about 5 to 10 seconds and then shut off show error code 71, the factory he’lp line said it’s time to replace it, do you have any suggestions, thank you very much
I just moved into this house … the water heater is working fine … but the remote controller doesn’t show any power, nothing … it’s dead. But the water does get hot. Any suggestions?
What do you know about closing the Water Servo-Bypass? It is in the instructions for the Noritz NR98-SV. I called they said I should do it so all solution goes through the (wherever the solution goes through) instead of this valve. I am so stressed now at this additional step that no videos and my plumber did not tell me about.
Question: can I use the same hose instead of new red hose after cleaning the tank? Really new hose to flush final step because mine located at ceiling.
I followed the steps in the morning, my son went to take a shower in the afternoon and the water was cold, when I looked at the tankless water heater, notice it was leaking from inside the unit. I hired a plumber to come, and he inspected it and said it was leaking from the coils. I am guessing the rust scaling must have blocked the hole(s) and once I descaled it then it exposed the holes.
My pipes freeze when it gets very cold which is about to happen. I understand I have to let both the cold and HOT water drip overnight. Is it okay to have the tankless "working" all night to let a drip occur?
Just a drip shouldn't activate the water heater, tankless water heaters need a certain amount of flow usually .5 GPM to activate, so you should be fine.
Adam Mammana . No, you did it correctly. You should unplug the unit never turn it off so the bypass valve remains open and the de-scale circulates through the heat exchanger.
Oh crap, I just learned about this maintenance. Our heater is over 10 years old, and never did this :( It has an external filter and it still says 'Clean'. Is that possible after 10 years? Hope the gauge isnt broken. I'm getting the parts together now to flush it this week. Do you think there might be any damage to anything? :(
The filter you have most likely has a media inside that runs out, the gauge only tells you when the filter is full which typically never happens, rule of thumb is change the cartridge once a year based on usage, using a cartridge with phosphate inside.
I have a RHEEM 199,000 BTU tankless water heater & the service manual for it says to use 4 GPM pump & circulate the cleaning fluid for 1 hour every year thru it & rinse with your fresh water for at least 5 minutes after flushing it out.
Hoping you will reply, my noritz unit has error code 16, even after descaling hot water will still shut off. This only happens during the winter time, Summer time hot water never shuts off. Any advice? Thanks.
Sorry for the late response, you will need to perform a gas pressure adjustment as well on the manifold, to be honest I would find a technician to do it for you.
No, when that happens your pump isn't powerful enough to activate the water heater, the work around for that is to run a large amount of hot water in the house, while the unit is running an heating disconnect power to the water heater this will lock all your internal valve in the open position, proceed to the next steps with the unit off.
Is it a Noritz unit, different manufacturers have different codes. Also, your pump may not be powerful enough to get the unit to try and turn on, I would suggest running a couple hot fixtures in the house to get the unit running, while its heating simply unplug the unit, then proceed from there this will open the valves inside the unit and insure the descaler is getting to the heat exchanger.
I have a recirculation pump on my Noritz tankless water heater. When I went to flush it I turned off the recirculation pump and followed all steps. I could not get the pump to pump water through the system. Either it is really plugged or I need to turn on the recirculation pump. The heater works fine but I bought the house and have no idea if the previous owner did any maintenance on it. I op-checked the pump and it works fine. Do you have any suggestions?

My hook tool has never seen a filter it can't remove, you may have to destroy the filter getting it out but it will come, make sure you purchase a new one before destroying the old.
How do we contact you? I have the same problem with the glove box lid on a 2009 acura rl; also the arm rest, and the coat hanger or hand grip in the rear. What is your email and address?
Just unplug the tankless. No error code. (Edit: It may need to be plugged in for Nortiz heaters to allow it through the exchanger. For Rinnai like mine, it does not) ruclips.net/video/8-ts7XuvS48/видео.html
You forgot to show us how to reset the controller in order to clear error code 11, but that doesnt surprise me. You also, forgot to solder your copper joints, you used the wrong teflon tape on the gas connection at the unit and no sealant on any of the rest of the gas piping. Yep, it was for a demo, but the reset of code 11 should have been in the video.
Correct, that unit wasn't actually installed, demo only. I like to store the codes so that if a technician comes out to service your unit he can see whats happened in the past, i.e. if you say you descaled the unit but theres no 11 code he my think it wasn't done properly, the most recent codes will show first.
If you ever take this video down I will go back to the old conventional water heater. This is the best video.
Great video. Probably on the best videos I have seen on cleaning out the Noritz Tankless water heater.... This will be my Go To Video every year :)
Great simple and easy video to follow. Need more like this for other household maintenance projects.
This is the BESST instructional video ever. So simple. Good voice. Clarity, and no extra drama. Thank you. Love Noritz!!!!
I just want to thank you for your informative and easy to follow video. I was able to follow along and successfully descale my water heater. 😊

How often do I have to do this maintenance wise?
Thanks for this. Great video. To the point , professional and simple
Very well done video. Used it today to do my heater. Was super simple to do.
Thanks I just did these steps on my 2021 Noritz tankless heater. Appreciate it!
How long did it take before the solution came out of the hot water hose? I don't know how long to wait before it starts coming out.

disconnect the communication cable between the 2 units and descale like described.
Thank you, the video was clear and useful. In your opinion, is the de-scaler worth the cost over just using vinegar?
Best video
What is the plastic plug on the hot water line next to intake cold water filter that you removed. How can you remove that one for cleaning it?

cocatfan ~ And now you have me stressed too...F#*k
The unit in the video is a NR98, follow the instructions and you'll be fine
if you run the pump till you get the 11 code, you're good.

yes, I just run mine out to the street typically

that happens with age.

Just a drip shouldn't activate the water heater, tankless water heaters need a certain amount of flow usually .5 GPM to activate, so you should be fine.
there's a high altitude setting on the unit, it has anti frost warmers inside
I performed this maintenance myself but I had the u it unplugged. Does this mean the exchanger was not open while the flush was being done?
Adam Mammana . No, you did it correctly. You should unplug the unit never turn it off so the bypass valve remains open and the de-scale circulates through the heat exchanger.
I watched another Noritz video that said Noritz leaves the unit on and plugged in. My plumber also did that when he showed me how to do a flush.
possibly
yes
Oh crap, I just learned about this maintenance. Our heater is over 10 years old, and never did this :( It has an external filter and it still says 'Clean'. Is that possible after 10 years?

Got it, thanks! I replaced the filter element and flushed the unit twice, an hour each. It was a breeze w your video. Thanks so much!
Should the code 11 beep the entire time?
Does it make any difference if our valves are on top? Not on the bottom? What about the size of the pump? 1/4 HP or higher?
I have a RHEEM 199,000 BTU tankless water heater & the service manual for it says to use 4 GPM pump & circulate the cleaning fluid for 1 hour every year thru it & rinse with your fresh water for at least 5 minutes after flushing it out.

regarding running the hose from hot water to the closest sink. Can i just run it to the drain floor since I have one there?
Yes, you can

@@SocalTankless hey no worries, we ended up changing heaters haha
How long does it take to flush 10-20 gallons of water through?
This
where do i buy the pump like what you sued? thanks
Harbor Freight
👍😎👍
3:43 how much liquid And water did u put in the bucket?
1 quart of descaler to 1 gallon of water or follow the instructions on the product your using
My noritz never went to error code 11 during the process - ran the pump for 75 minutes. Is that normal?
No, when that happens your pump isn't powerful enough to activate the water heater, the work around for that is to run a large amount of hot water in the house, while the unit is running an heating disconnect power to the water heater this will lock all your internal valve in the open position, proceed to the next steps with the unit off.
@@SocalTankless how often do I need to this maintenance?
no, the pump may not have been big enough to run trick the unit into firing. When you plug the pump in the unit should sound like its trying to run.
Where can I get an inlet filter removing tool?

Hard to say going off your description
There could be a check valve in the line between the heater and recirc pump, which would not allow flushing in one of the directions.
Can’t get the filter out, what’s my options.
My hook tool has never seen a filter it can't remove, you may have to destroy the filter getting it out but it will come, make sure you purchase a new one before destroying the old.

What about when u get error 71 ? What does that mean ?
Usually means your circuit board is going bad, I’m guessing you have an older model N-069M, I believe that part is no longer available
bad circuit board, if they make the part you can replace the board, if not you'd have to replace the unit
Here in california they charge you $300 for that🤤
That's incredible.
Why cover the pump with water and not white vinegar?
The descaling solution we use is to be diluted with water.
@@SocalTankless That is NOT what was asked
Just unplug the tankless. No error code.
