I'm a licensed plumber in Canada, and I just have to say I have so much respect for this person. An honest plumber is hard to find nowadays, and to find one willing to help instead of gouging the customer. That's a game changer. Keep on doing what you're doing, you're doing the world a much needed service and keeping the scummy plumbers away at the same time. :)

Clear and to the point with excellent camera work and audio. Whoever put this together ought to be teaching other people how to make instructional videos.
Given that this video is 5 years old...speaks volumes.... I couldn't just give a thumbs up and walk away. I gave a thumbs up to another video Ray did on servicing the Navien....but it wouldn't allow for comments, so I thought I'd just comment on this video since its essentially about the same topic. Ray - your videos are absolutely game changers. You explain things so well, I feel like I'm working for Water Heaters doing OTJT! Everything you covered was so thorough, it saved me quit a bit in service fees. If you guys were local in town to the Houston area, you'd be my plumbing company of choice, hands down. Thank You for a great PhD in tankless water heater maintenance!
We just used your videos to clean my Navien for the first time. I was intimidated, but we got it done. Thank you for providing such clear and directive instructions in your videos, and for saving me almost $500!
I did it! I did it, I did it! Watched your video about 50 times and was able to flush my tank and not blow up the house or break anything! Feeling so smart and accomplished and $200 richer! Thank you so much!❤️❤️❤️❤️❤️
Me too me too I watch this video o God knows and finally master it so happy happy widow my late husband is so proud of me right now ❤️. Last week my navien leaks called plumber $110.00 service fee right away parts is $47.00. Check Amazon parts was $34.00 now I know how to change it plumber won't be coming to my house thank you for this guy Ray.
Same except the second year I flushed it backwards, didn’t hurt the system but it did flush more junk, I suppose it was hidden debris that would not release if flushed the standard way.
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).
You are the BEST!!! I wish I had had your company install my heat and hot water system. The company I used has ripped me off royally. Thanks to your video, I just got my heat and hot water running by myself in the middle of winter on a holiday weekend. The company said they couldn't come until tomorrow with temperatures going down to the teens overnight. I just saved over $600 dollars! It is SO nice to see a company that cares about their costumers and don't rip them off! It is so rare these days.
This gentleman has provided a fantastic ‘how-to’ video. Every step is performed perfectly in order. There are other videos out there, but this is the best. Take notes or watch this video on your iPad and do as he does, pausing the video as needed. You can’t go wrong. Each step is explained at the proper time in the proper sequence. No cover is replaced or power switch turned on, until it’s time. It is my favourite ‘how-to’ for flushing my Navien water-heater.
This video makes me believe I can do this. Very clear, to the point. Thank you for having someone else film it so that I can easily see what you're doing.
Thanks so much Ray. This is my second year flushing my Navies heater following your instructions. I appreciate the DIY video, saving me the price of a service call for something I could easily do myself.
Thank you Ray for the detailed instructions. It was easy to follow. The first time it was intimidating but this second time this year it was much easier.
I've read over the Navien instructions many times, and I swear it doesn't mention cleaning out that dirt trap. I didn't even know what it was. Well, I did as you showed and wow, it birthed a nasty puddle of dirt and water into my bucket. Thank you for bringing this to my attention.
Thank you for this video! I'm about to have one of these Navien 240S units installed and it is great to know that there is a simple and complete guide I can refer to for regular maintenance of the unit. Your guide has given me the confidence to do the maintenance on a unit that hasn't even been installed yet.
I never leave comments but THIS video and this guy deserves it! Thank you so much! This is the most clear video I could find on the subject and I watched quite a few before I found yours! (I found the one from last year first and then this one). Thank you for being so helpful and so thorough!
I just purchased a Navien Tankless hot water heater today and was a little nervous about having to descale it on my own, but this step-by-step video is awesome! I've already entered the date on the heater when it was installed and when it's due for maintenance one-year from now. Thanks so much for this video!
So thankful for this How-to video. I was promised an initial flush from the Navien retailer I purchased from, only to get a verbal How-to, when he was doing something else. For someone who has never done this before, a verbal talk through is certainly not sufficient for me. I wish all company's held your standards! You made cleaning my water heater successful and easy. Thank you!!!
Performing my first flush. This video was immensely helpful. Maybe it's been updated, but I found I did NOT have to unscrew the vent pipe to get the top filter out. Just the screw holding it in, and it popped right out! Good Stuff!
Great video - thank you! I would like to add a couple of critical additional pointers that were omitted from your tutorial: 1) If there are multiple units running in Cascade mode, before flushing, you MUST FIRST take them out of Cascade mode, by doing the following (If you do not do this, the Cold Water service inlet will not allow water into the unit and your pump will be dead-ended): - Turn on all water heaters using the Power button. - On the master water heater, press and hold the Diagnostic and Reset buttons for more than 5 seconds. The water heaters will revert to independent operation. Then, turn the units off and they will be ready for flushing. - After flushing and maintenance are complete, turn on all water heaters using the Power button. - To reinstate Cascade mode: A. On the unit you intend to be the Master water heater ( I rotate mine every year), press and hold the Diagnostic and Up(+) buttons for more than 5 seconds. “MA.00” will appear on the display to confirm that this water heater is set as the master. B. On the slave water heater, press and hold the Diagnostic and Down(-) buttons for more than 2 seconds. “SL.01” will appear on the display to confirm that this water heater is set as a slave. C. Repeat step 2 to configure the rest of the slave water heaters in the system, i.e., "SL.02"... D. On the master water heater, press and hold the Diagnostic and Up(+) buttons for more than 5 seconds. All the display screens on the configured water heaters will return to the temperature display. 2) If you are using External Recirculation, don't forget to clean that Recirculation Inlet filter in addition to the Cold Water Inlet filter (they are exactly the same filters). 3) After draining and before flushing, DO NOT FORGET to move the lever on the Safety Relief Valve back down to its normal operating position! I learned this mistake the hard way, after I had pumped 5 gallons of vinegar into the drain because the safety valve was still open!! DUH LOL!!
Ray, THANK YOU for this easy to follow instructional video. I purchased a flush kit, complete with descaling solution, hoses and sump pump. It was very easy to do, following your video and I have placed a reminder in my calendar for next year to repeat the process. I called a plumber who wanted $475 to do what cost me $140 to purchase the kit. Peace and blessing to you!
I think this is the best video for" how to '" on youtube period. I'm a retired General Contractor and do all my own work with the help of youtube, so I watch plenty of videos. Thank you !
You are awesome to do this for your customers and you saved the day for me when my Navien just stopped sending hot water - your steps got it back and running again!! Thank you!!
It shall be well with you and your family and your entire workers for this great help to the teeming public looking for help of this kind. On the 7th of Jan 2022 I woke up from sleep to my heater not working anymore. And I don’t have even $50 I could give to anyone coming to repair. I did everything I could do with one of my good neighbors but to no avail all the night. I went to sleep and woke up on 8th of Jan 2022 at 11 am and followed all your instructions here and my heater came back to life. Many thanks bro for your immense help. I live in Edmonton Canada 🇨🇦.
Great video. I never knew I needed to do this until today. I have (2) Navien tankless heaters in the house & they’ve been in operation now for about (6) years (since Hurricane Sandy). I imagine they need some attention after all that time!
Thank you. A plumber told me that they use a special chemical to clean the tank and it will cost me $600 each year. This video has saved me my hard earned money
Called a plumbing company and they wanted to charge me $250 to descale my navien. I really like this plumbing company as they always do very good work, but in this case, I’m glad I held off and decided to see if I could do it myself. This is easy stuff, the only thing you need to get is a submersible pump. Those go for $50. 2 gallons of white vinegar = $10. So my first go around I will already have saved myself $190. And cleaning after that, I’ll keep $240 in my pocket. And all because of this video! Thank you for putting this on.
This was the best video. Thank you for sharing your expertise and explaining every step of the way. Your honesty and thoughtfulness are so appreciated. Well done!!
Just cleaned mine on a new construction house after 3 years. And I was expecting for the vinegar to change color like I watched in another video, but it stayed the same color. For context I live in the country on city water just north of Spokane. The dirt trap was dirty and the cold air filter had like three dead bees. The cold water intake filter was clean as well. Thanks so much this video was amazing step by step guide.
Fantastic How-To Video! If I lived in your area, you'd have my business hands down. Great work and I appreciate your desire to help customers and homeowners have success in maintaining their investment!
Thank you so much for such clear and detailed instructions. I had my water heater installed by a different company two years ago and just cleaned it out with your tutorage. Thank you very much.
Fantastic video! Just cleaned my Navien heater following along step by step with the video. Mine is an older model than the one in the video but the process is the exact same. Thank you very much, Ray!
Ray explained this better than all the others on you tube. I did see some galvanized plumbing on that unit. I hope it has isolation spacers placed or corrosion cell could form on the unit. I like the way the plumbing on this unit is spread out wide, makes it so much easier to get to all the valves. Thank, Ray awesome presentation.
True! Had my tankless unit going on two years (house remodel) and this morning got error E016, which I Googled and found filter needs cleaning and heat exchanger. I did unplugged for 30 min and plugged back in and unit working good. But I see I will need to service, MY SELF! :) Save me some mula! :)
Thanks so much for this FREE tutorial! I've now performed this twice in the past year after experiencing warm water with 'hot' turned all the way up. We were able to survive a few days by 'tricking' the system--we'd run 2 faucets when we wanted hot water from 1. The whole process can take about 1.5-4 hours, depending on your skill, availability of tools, and access. We used a non-submersible pump from Harbor Freight both times. It's just a matter of matching up the correct fittings...
Awesome tutorial, I just have to snicker at the dryer hoses you had originally hooked up with cold to hot and hot to cold, then the next frame they were correct. Nice catch! Thanks for a great video.
Exactly what I needed, hard to find good info online. I do everything i can myself. I was having issues where hot water would stop for a bit, then come back without codes/system shutdown. Pulled everything apart and cleaned everything. Tons of crud/scaling. Took me a good few hours seemingly the unit was never maintained. Now heat is great, no more hot/cold/hot showers thanks so much.
Just flushed my Navien tankless for the first time. Your step by step instruction is well illustrated and worked perfectly. Thanks again for a great video.
By watching this video it helped us to turn the water heater back. We were not getting hot water but by cleaning as per instructions it worked . Thank you for sharing and help us save some money .
Fabulous video! Great detail, step-by-steps and really good photos or the parts. Thank you so much! I am a 66 year old female and was able to accomplish this task easily!
Thanks so much for making this!! I watched your other video and i couldn't quite see how to open the service valves. This one is more clear. Thank you!!!
Use this video as a reference every year when I clean our Navien. I'm so glad I found this video. It makes it easy to navigate through the steps even though it's not the exact model.
This is my 4th time using this video to clean and service my NAVIEN Water heater. I appreciate so much the clear and concise information in this how-to video. I totally agree with one of the other comments, that you should be teaching others how to make instructional videos... THANKS
Very good instructional video. Thank you . I wrote down every single step for future reference. At the beginning of the video Ray unplugged the water heater from the wall, but at the end of the video he forgot to mention to plug the Water heater back in the wall. It's a little detail that might confuse some people. Thanks again for a good instructional video.
OMG - saved me hundreds of $$$. Sure I bought I pump for $79 but moving forward no cost involved. My showers were becoming like the old hot water days of half the shower warm the other half Luke warm even with tankless. Followed his step-by-step and system is operating like day one install...endless hot water! Great job and THANK YOU!
Thank you so much! We bought a home with this hot water heater, had no idea how to clean it but now I do! Truly appreciate your knowledge and experience!
I just got two Navien water heaters installed and this is exactly what I needed! I’ve seen some other videos on the subject, but none as detailed as yours with showing the various filters and traps. Thanks a bunch! 👏🏼 👏🏼 👏🏼
Very nice video the best part is the o ring on the dirt trap if you hadn't told that part is so sneaky it gets stuck while pulling out and wouldn't know it was suppose to be there. 10/10 for this tutorial. Thanks

Great video - thank you! I would like to add a couple of critical additional pointers that were omitted from your tutorial:
1) If there are multiple units running in Cascade mode, before flushing, you MUST FIRST take them out of Cascade mode, by doing the following (If you do not do this, the Cold Water service inlet will not allow water into the unit and your pump will be dead-ended):
- Turn on all water heaters using the Power button.
- On the master water heater, press and hold the Diagnostic and Reset buttons for more than 5 seconds. The water heaters will revert to independent operation. Then, turn the units off and they will be ready for flushing.
- After flushing and maintenance are complete, turn on all water heaters using the Power button.
- To reinstate Cascade mode:
A. On the unit you intend to be the Master water heater ( I rotate mine every year), press and hold the Diagnostic and Up(+) buttons for more than 5 seconds. “MA.00” will appear on the display to confirm that this water heater is set as the master.
B. On the slave water heater, press and hold the Diagnostic and Down(-) buttons for more than 2 seconds. “SL.01” will appear on the display to confirm that this water heater is set as a slave.
C. Repeat step 2 to configure the rest of the slave water heaters in the system, i.e., "SL.02"...
D. On the master water heater, press and hold the Diagnostic and Up(+) buttons for more than 5 seconds. All the display screens on the configured water heaters will return to the temperature display.
2) If you are using External Recirculation, don't forget to clean that Recirculation Inlet filter in addition to the Cold Water Inlet filter (they are exactly the same filters).
3) After draining and before flushing, DO NOT FORGET to move the lever on the Safety Relief Valve back down to its normal operating position! I learned this mistake the hard way, after I had pumped 5 gallons of vinegar into the drain because the safety valve was still open!! DUH LOL!!

Awesome tutorial, I just have to snicker at the dryer hoses you had originally hooked up with cold to hot and hot to cold, then the next frame they were correct. Nice catch! Thanks for a great video.
Excellent instruction. Thank you very much for this very good man.
Thank you, Ray & Water Heaters!
Excellent video! Clear, concise and to the point. Watched it a couple of times before doing the job and didn't encounter any issues. Thanks.
Exactly what I needed, hard to find good info online.
I do everything i can myself. I was having issues where hot water would stop for a bit, then come back without codes/system shutdown.
Pulled everything apart and cleaned everything. Tons of crud/scaling. Took me a good few hours seemingly the unit was never maintained.
Now heat is great, no more hot/cold/hot showers thanks so much.
Just flushed my Navien tankless for the first time. Your step by step instruction is well illustrated and worked perfectly. Thanks again for a great video.
By watching this video it helped us to turn the water heater back. We were not getting hot water but by cleaning as per instructions it worked . Thank you for sharing and help us save some money .
Fabulous video! Great detail, step-by-steps and really good photos or the parts. Thank you so much! I am a 66 year old female and was able to accomplish this task easily!
Thank you. These directions were easy to follow and also apply to a Navien NPE-240A2.
Thanks so much for making this!! I watched your other video and i couldn't quite see how to open the service valves. This one is more clear. Thank you!!!
Totally awesome. Got my Navien installed yesterday and the company offered a $250 maintenance plan and gave me 30 days to add it. Crazy stuff!
Use this video as a reference every year when I clean our Navien. I'm so glad I found this video. It makes it easy to navigate through the steps even though it's not the exact model.
Thank you for taking the time to make this video. It shows that you really care about your customers. That is a rare quality these days.
This was a perfect how-to video. I performed the maintenance on my Navien water heater today with confidence after having watching the video.
Thank you for the video. I just did my Navien according to your instruction. Mine is a little different, but similar enough.
Best all-inclusive video I have seen on this subject (and I looked at a few). Thank you.
This is the best video on tankless water heaters I've ever seen!-- and I've seen alot--I can't think of a thing you left out.
This is my 4th time using this video to clean and service my NAVIEN Water heater. I appreciate so much the clear and concise information in this how-to video. I totally agree with one of the other comments, that you should be teaching others how to make instructional videos...
THANKS
Thank you for the video! Just installed the 240S in my house.
Very good instructional video. Thank you . I wrote down every single step for future reference. At the beginning of the video Ray unplugged the water heater from the wall, but at the end of the video he forgot to mention to plug the Water heater back in the wall. It's a little detail that might confuse some people. Thanks again for a good instructional video.
I"m flushing my Navien tankless today. Thank you for creating a helpful and consise instructional video with such clear instructions! Great job!!!
Great video - just serviced mine and your instruction was spot on!
OMG - saved me hundreds of $$$. Sure I bought I pump for $79 but moving forward no cost involved. My showers were becoming like the old hot water days of half the shower warm the other half Luke warm even with tankless. Followed his step-by-step and system is operating like day one install...endless hot water! Great job and THANK YOU!
Thank you so much! We bought a home with this hot water heater, had no idea how to clean it but now I do! Truly appreciate your knowledge and experience!
No amount of Thank you can do this video justice. But, thank you, thank you, thank you. Your explanation is superb!
Excellent step-by-step overview. Thank you for posting!
This is a great video - thanks! I haven't serviced my unit in 5 years but now know what to do. Very clear and concise instructions!
Greatly appreciated, thank you for the hands-on detailed instructional video on how to maintain our Navien Tankless Water heaters!!!!
Have one of these in the house we bought last year. Very helpful video! Thank you!!
Very helpful. Getting a Navien installed in about a week and I saved this video to refer back to when I need to do routine maintenance.
I just got two Navien water heaters installed and this is exactly what I needed! I’ve seen some other videos on the subject, but none as detailed as yours with showing the various filters and traps. Thanks a bunch! 👏🏼 👏🏼 👏🏼
Thank you for uploading this. Much respect.
This tutorial is very thorough and easy to follow. Thank you!
Very nice video the best part is the o ring on the dirt trap if you hadn't told that part is so sneaky it gets stuck while pulling out and wouldn't know it was suppose to be there. 10/10 for this tutorial. Thanks
