Different valve kits for a Rinnai tankless heater
HTML-код
- Опубликовано: 7 ноя 2024
- There are many different valve kits on the market some are really good and some are not so good!!!!!
Here are a list of the valve kits I have found to be very good.
Remember to always use a good valve kit with the proper relief valve rated for the BTU'S of the unit you are installing.
Use a valve kit that costs at least $80.00
Valve kits
The two Rinnai kits are the same number-MlVK-T-LM
RU and RUR kit- 107000284
Easyflex has no model number
I hope you enjoy this video,
Mike
PLEASE USE A LICENSED PLUMBER TRAINED IN LEVEL THREE RINNAI TRAINING. FOLLOW ALL NATIONAL AND LOCAL PLUMBING AND GAS CODES AND TO FILE A PERMIT AND OBTAIN AN INSPECTION.
Best channel for information on Rinnai tankless.
Why thank you very much
thank you very much
What a class act you are. Thanks for helping the not only plumbers but regular joes like me and I am learning so much from you. Thank you from the bottom of my heart
Hey Mike thanks for all your help. The wife was ready to send this unit back before we found you haha! ... You really helped us out.
Anyone else reading - this is the guy right here.
Glad to help
Mike, you are a great man. Spending your free time making these videos to help those of us that have these tankless units with issues. And you even take the time to reply to emails and are willing to take the time to talk with me on the phone, Unheard of really. I cannot say enough about how you are willing to help others out! Keep up the good work, and continue to keep yourself safe. I look forward to seeing more of your videos on the tankless units, and thanks again!
It’s probably the pressure reducing valve that’s bad or clogged. You need a plumber to clean or replace it. Mike
Thank you for your service Mike. Your videos helped troubleshoot my Rinnai water heater and I am getting hot water again. Wishing you nothing but the best.
Mike, thanks for breaking down the difference in service valves, I’m always looking for durable products to install for my customers that will last down here in the hard water, and salty florida atmosphere. Appreciate all the info and tips!!
Glad to help
I'm so impressed with all the information that you have put out. I just bought the exterior unit and works great. I'm a home owner but very knowledgeable in working with plumbing and carpentry. Installed the unit myself. With a little help from a friend. We used every video that you showed and completed in a couple of hours.. Thanks so much. Dennis.
Thanks I’m glad the videos helped. Mike
Mike....how does the bypass valve work on the tankless heater? I'm thinking when you go to flush the unit...with vinegar ...that bypass valve needs to be closed or the only thing you're flushing is the bypass circuit. Am I correct? I think once you get the flush going...you power the unit up...the bypass closes....then just unplug it.
Thanks Mike. Watched several of your videos and I have learned a lot. I just installed a RUCS75i unit replacing a 24 year old tank water heater. I bought a valve kit several years ago for another tankless heater and used it on the new Rinnai. I bought the Watts kit from Menard. Thanks again Mike
Glad to help
mine has a flow restrictor/sediment trap on the cold valve, did yours?
You're exactly right about those non stainless shafts breaking! Finally, someone that knows
I don't care for any of these valves. The service port valve handles and isolation valve handles are always too close together and difficult to turn by hand and or with pliers. Pliers because when I get a service call, 100% of the time they've been sitting for 2-5 years without turning and is difficult to turn by hand.
Installing a dedicated return (dedicated recirculation return line) line voids the warranty or reduces the warranty on Noritz tankless water heaters. I'm certified with both Noritz and Rinnai but I prefer working with Noritz because they have their own in house tech support, training, sales and warehouse with parts in Southern CA.
Can't beat the EZ series 25 year warranty on the stainless heat exchanger. Made in Japan.
What I don't like about Noritz is they're selling a cheap Korean tankless water heater, a company called Kiturami (The Korean company even used a Japanese looking name to fool people. It uses Chinese parts, it's total crap. It has the Noritz name and model NRCP1112 but it's not a Noritz and it's not made in Japan.
Hi Mike, thanks for the helpful video. Our Rinnai has stopped working, we cleaned the heat exchange unit, and flushed the entire system, still get the error code 14, looks like no gas is allowed in, I'd appreciate it if you could please advise if we need to change the thermal fuse, or sensor wringing harness or bimetal safety switch. thanks again
Thank you so much for all your knowledge and information that you pass on through these videos. Very helpful.
They need to watch the Myth Busters Vidoe with relief valves removed! Great video Mike! They turn into rockets with out that very important safety! The relief on the Sensei you can get the relief only! It comes with the 90 but you do not have to get the complete valve kit!
Thanks for the info and I did see the episode thanks Mike
@@TheBuddylab hey notice your the plumber guy here and since your videos are awesome I not only subscribed here but also your woodworking channel too
Mike, you are so amazing and so thorough. I truly appreciate your knowledge, helpfulness and your clarity. Thanks to you I purchased a Rinnai. I am working to set up my tankless to recirculate to my existing First Co. Hydronic Air Blower. My questions right now are related to the threading on Rinnai isolation valves as well as the IPS threading you mentioned related to the Rinnai DRV in the excellent DRV video you did. My RUCS75I manual says the water inlet is MNPT while the hot water outlet is MSPT. I understand MSPT is straight pipe threads so I suppose its an FIP connection. I was hoping to use the Rinnai DRV
No if it a Rinnai valve kit not fires are plumbing threads. Thanks for such a great comment.
I just watched your video on the different valve kits for the Rinnais. It is one of the best, well explained videos I have seen. Out of the blue my Rinnai started leaking at the union on the cold water valve kit. the washer seems fine, and the plastic ring it sits in seems fine also. wondering if you have any suggestions?
Great Video! I just bought a v53DeP and ready to install it next week.
I just bought the same model, did you put the electrical and controller wire through the Quick Cable Connection or did you do a separate electrical and if so where. The Quick Cable Connection is and odd size and I can't figure out proper installation.
I feel more confident I can install my new (returned) Rennai correctly using your videos.
I’m glad it helped. Good luck with it. Mike
I have a Rinnai RU199 (not the RUR199) installed with an EXTERNAL recirculation pump. I assume there is no filter installation as you show with an RUR199 unit. All I need to do is to install the recirc valve at the right location and install the recirculation pump on the RU199 hot water discharge. Is this correct. Also, it appears you can wire the EXTERNAL recirc pump up to the Rinnai RU199 circuit to control the external pump from the unit.
I got a head scratcher for ya. i120cn with 2 Taco 007e zone pumps and Nest stats. When I use domestic hot water, the zone pumps click on for a second and circulate through the heating loop. Currently both stats are off, why would my zone pumps click on if I’m only using domestic water? Thanks in advance
I have an older rv53 and went to.service it and the hot water turn off snapped of just like you said. Fortunately. It only has a very slow drip approx every 5 secs. How soon. Do.i need to. repair this ? What valve would you reccomend
Thanks
I have a RL94 with the Westone valves. Just as you said my cold water handle valve broke off and now has a moderate leak. Very frustrating considering I’m staying on top of servicing this water heater to prevent things like that from happening.
Do we have an video how to clean the three way valve cartridge?
Hi Mike, I have a Rinnai I turned the water on it got hot then turned cold the same for bathtub and shower went to check outside saw water that dripped and turn to ice its been really cold in the afternoon got warmer now the hot been working do you think i need reg or broken dip tube ty Lisa M.
You will definitely need to see inside the unit if it’s leaking
i just got a v unit and watched 4 videos . it seems like ill have an easy install. thanks
How did the instal go? Just curious think of replacing my old rinnai
@@BigOsTaco AS EASY AS UNHOOKING THE OLD HOSES AND PUTTING THE NEW UNIT IN
@@flatearth9140 thanks. If my keeps giving me hell might just replace it. Thanks again
@@BigOsTaco THEY ARE PRETTY SIMPLE. WHATS WRONG WITH IT
@@flatearth9140 it will heat and fire up if my water stream isn’t strong but if I open up the valve a bit it tries then shuts down and get code 12. I have already removed the fan took some bug outs. Took out the flame rod and ignition rod and cleaned them good with green scribbling sponge and brought the shine back. I also hired someone and they took the burner plate off and used a air compressor and cleaned it but still code 12. I also already replaced the inlet filter just in case. I even bought new flame and ignition rods and same. The unit was built in 2008 and installed in 2009 so I thought maybe it’s time to replace. I get hot water but as long as the flow is low maybe 1/4 to 3/8 the strength of faucet. Anyhow that’s it. But the unit is clean always flushed.
mike i just install a rinnal ru160i everything is good but the problem is i got a litle water from prv vale every day can you tell me how to find the solution thanks
What is model number on valve with built in union?
Do all these valves work on the V series exterior?
Yes they do
Mike I'm putting in a electric tankless heater, Non Rinnai (I don't have Gas) which valve Kit do you recommend?
You showed the valve that does not work very well, but I did not hear you say the brand it was .
Brass Craft tankless valve kit
Mike, very informative video. Thanks so much for your knowledge. Question. I have a Rinnai RUR98 that is 5 years old and when the plumbers were out today to do yearly maintenance, they said they could not perform it because the valves were not working, they could not shut water off going to the unit. So, valves need replacing and they are wanting $650 to replace and maintenance. Sounds high to me. What valves would you recommend for replacement? The ones that were on it came with the unit and they were the longer ones you showed in your video.
$650 is very high I charge around $400.00 and I include the servicing. The Rinnai ones I show in the video are the best ones to use. They have the built in unions and the insides are all stainless steel. I hope this was helpful Mike
@@ThatTanklessGuy Thanks Mike for the follow up. Do you make house calls to Tennessee;) I am in the process of trying to find a Rinnai certified tech such as yourself in my area and get a quote from them. Thanks again for your help and information. Be safe:)
@@ThatTanklessGuy Mike, I am still dealing with my RUR tankless yearly maintenance. Plumber was out a week ago, performed maintenance and the following day my controller started beeping and display was black and flashing the number 11. I have tried to get plumber back out but having difficulties. Any ideas on the 11 code?
@@stevejensen5129 that’s ignition failure did you try to reset it by unplugging the unit for a minute then powering it back up. Did it happen again after that?
@@TheBuddylab Thank you for the follow up. I watched your video on the code 11, great information. Plumber was back this morning and on the phone with Rinnai. They could not get the pressure to hold when max flame came on. Having to replace the heater. Ouch! Apparently the plumbers I had doing maintenance on the unit were not certified and did not know what they were doing.
Mike, you are awesome! I'm not sure where to ask this question cause you may have already talked about it in a previous show but is there a difference between a propane regulator and a natural gas regulator? I am installing a V53DeP on a 20-foot off-grid container that I will be using for a guest house or as we say here in Hawaii an 'Ohana'. I have a valve kit--sadly not the best one apparently but I guess it will work for a while. What I intend to do is simply use a propane bottle for the hot water heater and a small cook-top stove. Do you have suggestions on what regulator to use. Thanks in advance and I'll keep looking at some of your other videos cause maybe you went over this question. It seems like you cover just about everything. Aloha for now.
I suggest you contact your local propane company because depending on the size of the tank and if it going under ground that’s the piping there are a bunch of different regulators
@@ThatTanklessGuy Mike thanks. The tank I was going to use was either a tank that one uses for a BBQ or one that is just a bit larger (almost three feet tall). Do you think the regulator that I currently use for the BBQ would suffice? I'm thinking I would want a much higher quality (and more volume?) such as the ones you show on your channel. Thanks again for your time. Aloha from the Big Island
Does the RUCS75IP come with the valve kit ?
Hey, I have a few quick questions I am having hard time confirming on my own. I am confused about how the boiler drain valve attaches without being in the way of isolation valve. I’m novice (am great at the application once I understand) and struggle with all these terms and of course some of these terms are hard to clarify with Google. Reading the diagram I see I need a 3/4” union. I looked at the isolation kit I have, and it looks like there is a union with it but I’m not sure if I should be creating a line from unit to isolation valve or if iso valve connects directly to unit. I’m assuming I’m confused because the diagram isn’t using the words “isolation valve.” I’m guessing boiler valve is isolations valve but I just can’t get a straight answer. Please help!
Can you send me some pictures to my e mail and I will take a look at them. Mike
@@ThatTanklessGuy I was actually able to figure it out and get up and running! My iso valves are boiler drain and shut off!
Mike, I need to get the washer that goes on the pressure relief valve. You show it in the video at 20:20. Do you have any idea where I can get it or the exact size? Any help whould be greatly appreciated. Love the videos and thanks so much. David
That washer only comes in the complete valve kit. when I had a bad one Rinnai sent me the complete valve kit. That was months ago I don't know if they offer that separately now, Mike
I need help, to diagnose my tankless water heater.
Does home heating water mix with the DHW?
awesome video great information
Mike, where should this valve be located?
You are joking about the old valve kits. I hold my breath when turning those. Lol
Lol same here
Great review today.
If the two Rinnai kits use the same number, is there any way to know if you're getting the one with the integrated union versus the one with the union that comes off?
Btw, I think the Rinnai number is supposed to be MlVK-T-LW vs MlVK-T-LM
Yes that’s it typo O
I had the same question. It's not clear how to get the newer Rinnai single-piece union version. All the pictures for this model number online seem to be the two-piece.
Where are you guys buying the Rinnai parts at?
@@BigOsTaco I got the valve kit from an eBay seller but the other parts from Supply House
Happy Thanksgiving! 🐇
Lol thanks
Love your videos and great info. Be safe.
Thank you very much
Thanks Mike
Hi Mike, Rinnai Guy, I have a Brand new Unit, Modell #: RUR199en; when I shower after 3 minutes, the water getting cold. I have to shut down my shower valve and reopen it to get hot water again. I have two Bathrooms, Shower; both do the same thing. So far in the past about 10 months, nobody would help me; just FYI, I changed my Gas meter from 2 Cub Ft to 4 Cubic Ft; my Gas Pipe is about 2.5" in diameter my water pipe is approximately 2.5" in diameter. Both Bathrooms are about 10 FT away from the Unit, and the last thing I have Recirculation pump and a loop; also, I did change my shower valve, but still I have the same problem. It is a brand new construction. I would appreciate it if anybody can solve this problem.
Call me at 19042385349 today after 7pm eastern time and I will go over it with you Mike
I changed my shower head and now I don't get hot water anymore. WHY?
Low flow shower head take out the water restrictor from the shower head.
Navien I think is much better
