Navien Tankless Cleaning Water Heaters Now 

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. :)

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!❤️❤️❤️❤️❤️

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!

One of the best 11min spent in my life seriously..

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!

Best tankless service video I've seen on the web, HANDS DOWN, and I'm a licensed plumber. Nice work!

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!

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.

Did my first flush today and am so grateful I had this video. Thank you for making such a high quality, detailed video. Fantastic job!

This was an exact replacement for the old one that lasted about 10 years. ru-vid.comUgkx7yWIKcrbA9KMHkGSfcgxW2lsjHT6B8Sh 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.

You have explained this so thoroughly. This was extremely easy to accomplish for this stay at home mom on a budget!! Thank you!!

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!

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.

I watch this every year as a refresher just before I do this to my Navien °T-CREATOR dual unit.

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.

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.

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!

I've self-serviced my Navien these past four years, based on this well-done explanation of the maintenance procedure. Thanks!

I just finished heater flushing by your instruction. I saved $200+ because of you. Thank you.

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 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!

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!!!

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.

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!!

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 !

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

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 🇨🇦.

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!

One of the best “how to” videos I’ve seen. And highly commendable that this company is straight up and honest. Too cool!

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!

Thanks, Anybody that does a video like this has a great business that can be trusted.

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...

Amazing video. I own one of these heaters and thought I was flushing it right, but now know there are more filters. Thank you so much

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.

Third year in a row I am using this video for my yearly flush. Thank you so much!

excellent presentation of how simple this process is and why it is so important to do each year.........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.

I wish all DIY videos were as good and professional as this! Thanks for this!

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.

You saved me $250.00 and now I have invested on a water pump to do my regular maintenance. Thanks again!!!

Thank you Ray for a methodical, step-by-step process in this procedure..

Clearest and best service video I've seen on a tankless water heater. Just saved 300 bucks!!!

Thank you so much for this thorough detail. Cleaning all the traps and filters were super important and not many other videos explain that part - those filters were nasty in just one year! There is no way I would’ve been able to do this without this video. Thank you so much 🙏🏼

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!!

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 .

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!

I’m a master plumber and this was a great video I’m going to start descaling the tankless units I put in.

Am a plumber and this video is a excellent step by step video on tankless maintenance.

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

Using this video for a few years now... Thank you for keeping it up. It continues to help.

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!

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

one of the best instructional videos i have seen in years...thanks for being so patient with an audience, who like me, might need baby steps....great work

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.

Thanks for this. I've come back 4 year in a row to perform this easy maintenance on my Navien.

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.

I watch this video once a year when I clean my water heater. The company that installed mine was great and did a wonderful job of installing my Navien and explaining how it works. But they do not explain how to descale it because they charge a lot of money to come once a year to clean it. I've never had to pay them to do that, thanks to this video and the purchase of channel locks. Thank you!

Very well done presentation. Thanks for taking the time to do it for everyone.

I watch this tutorial step by step as i descale my Navien system today. Very helpful. Thank you so much! 👍💯

Excellent video. I have a Navien tankless. I've been doing the annual vinegar cleaning for a few yrs now on my own. I didnt know about the cold air inlet filter or the dirt trap Easy fix! Mine was full of small bugs on the air inlet and had some dirt in the trap. Thanks for those 2 segments. I will add to my annual maintenance.

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.

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!

Really great video. Love the step by step to take out any confusion of what to do when! 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.

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 god for videos like this. I wish I lived near this guy so I could buy a system off of him.

This was a perfect how-to video. I performed the maintenance on my Navien water heater today with confidence after having watching the video.

I have used this video every year for the past 5 years. What an amazing resource and so, so easy to follow. Thank you so much for doing this!!

I wish you & your company were local to me, as I would hire you hands down. Too many plumbers in my town want to take advantage of me. The ones that installed my Navien told me that I never needed to service it, and they did not install service valves as you so rightly did. Your customers should be thankful. I'm grateful for your video. Keep up the good work.

I watched this and followed the instructions, saved myself $160. Easy if you have the small sump pump, which I do. Many thanks.

I"m flushing my Navien tankless today. Thank you for creating a helpful and consise instructional video with such clear instructions! Great job!!!

No amount of Thank you can do this video justice. But, thank you, thank you, thank you. Your explanation is superb!

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.

This is one of the best video's I have ever watch. Thank you so, so much. I live in SW michigan and have had a really hard time finding plumbers to come out to service my On demand. I followed this video today and did it myself. Worked great!!!! Thank you so much. Laura

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! 👏🏼 👏🏼 👏🏼

Your video on descaling my navien water heater was excellent. Hot water lost last night. Hot water today by noon. Thank you!!!

Best review yet. Clearly spoken and understandable. I got caught last year on the dirt trap because the O ring slipped off and left me in a lurch...no info on it. But now, yes Sir! Great job.. and tanks or thanks!

Thanks Ray for posting this instructional video. My contractor never said a word about annual maintenance on my water heater. 6 years in, I could tell that the unit was not running efficiently. With the descaling, we have noticed a marked improvement on how fast hot water is available! Easy to clean and maintain. I’ll be doing my neighbors water tank next, since she has the same unit that I have. Best Regards to you and your team!

Great video, thank you. A few things I did after I was finished with the flush. #1, I took the used bucket of vinegar outside, and before I dumped it out on the ground , I neutralized it with a cup of baking soda , and poured it out where there were no plants close by. I didn’t feel comfortable pouring it down a drain into my septic system. # 2, I rinsed everything thoroughly with water that had come in contact with vinegar , including hoses, pump, and tools. # 3, have an old towel rag near by when you are doing the flush, because you will get some water or vinegar on the floor.

Thank you for this video. I paid the plumber to do this service twice, what they charge is more than what i want to pay. My son and brother did this simple maintenance with me referring to this video when we weren't sure. It is so simple but my tank is outside mounted on the wall. If i had to do it again i would never install it outside. The cold water pipes will freeze and all it takes is one time for this to happen and mine did the first two years of installation. I blame myself for dreaming on that no freeze thing. But at least it's not in the crawl space like my electric heater was. So far no more freezing but outside unless it NEVER gets below freezing don't . The only mishap was they forgot to brace the hose during the descaling and got a vinegar shower.

This is one of the BEST instructional videos I've ever seen. Bravo!

Best video I have seen on any topic in a long time. Thank you!

I have been referring to this video every year for the last 5 years to maintain my Navien. Best investment I have made to my house. Ray, I hope you are still with the company because you deserve a raise!

Awesome video. Thanks so much for the VERY clear instructions 👍. My cold water filter was almost clogged from hard water and debris after just one year. Flush kit instructions don’t mention it, so great tip!

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.

Thank you for detailed video, I installed Jomar tankless water heater valve, so making cleaning much more simplify, no garden hose needed, less valve to close/open.

I just followed your step by step instruction and it went as smooth as silk! I invested in a sump pump & hoses & I figured it has already paid for itself. One thing you didn't mention was to flush out your sump pump after to get rid of the vinegar. THANK YOU!!

I would hire you in a heart beat! The world needs more trades people like you!!

You are a scholar and a gentleman thanks so much 👍

Excellent instruction. Thank you very much for this very good man.

I watch a walk through on doing this every year just to make sure I don't forget a step. This is the best one anyone has done yet! No one ever mentioned the dirt trap in the previous ones I watched so mine was nearly full. Thank you! I have a Navien NR - 240A. Is the water filter in a different location or is my model not equipped with one? Awesome video!

This is the first video that clearly explains how to do all this. Thank you!

Thank you. These directions were easy to follow and also apply to a Navien NPE-240A2.

Fantastic video. Lucky enough to purchase our first home, and it came with one of these water heaters. You guys are awesome, thank you so much!

This is such an amazingly helpful video so I want to thank you for this!!!! So easy to follow, there were no points of confusion, and you even helped explain even further with the handful of text overlays. Very patient, and well done video with excellent audio levels and video!!! This helped me become a rock star with my wife because we now have hot water again! After I cleaned the two filters and 'pin trap', we were good to go! But, each faucet and shower head needed to flush out for about 30 seconds with quite dirty water, I was wondering if this was expected? Also, when I cleaned the hot water filter...it was greasy to the touch. Really odd. Lastly, the clowns who put the unit in, they torqued the hot water maintenance valve in a position where it is impossible to maneuver a drain onto, there is about 2 mm of space between the maintenance valve cover and one of the mains that feed the unit from the bottom. I'd have to dismantle the hot water lead significantly, which I am definitely not skilled enough to do.

This tutorial is very thorough and easy to follow. Thank you!

Fantastic video!!! Saved me a service call. Just wish you were an option over here in Michigan!! Much respect and appreciation!!
