- Part 5 of the series on the RUR condensing unite.
The condensate drain it probably one of the most important parts of the Tankless. without it the tankless will go into code 25 and not operate.
If you follow these steps you will not have one problem with it.
That CPVC female adaptor can be bought at Home Depot or Lowes.
The storage boxes can be bought at www.systainer.store.com
Have a licensed plumber that it certified in level 3 training by Rinnai install your tankless. Follow or state and local code and to file a permit with your local building dept.

I hope you enjoy this video.

Mike, you solved (my) inexplicable question as to why my overflow/catch pan was full of Really Old water (my units up in my attic where I don’t check often enough.) Install plumber put a chicken sh*t (wedged-in) non-mechanical fit to the bottom of the condensate drain, and it leaked profusely over time. Now fixing-up the fitting configuration as per your recommendation... Much thanks for your expertise Mike!!
Mike... I can't thank you enough... Your videos provided ALL of the guidance I needed to install a RUR199in this past weekend. 100% success! Started 9a Saturday and finished 9p Sunday. Because of the detail in your videos, I didn't have a single question. I used Pex-a until I needed to interface with existing copper, at which point I used sharkbite (not my favorite, but I don't have a propress). Thanks again, sir. You rock!
Wonderful tutorial. Helped a ton with our Rinnai condensing unit.
Mike, I finished my install, thank you very much for all your help , sharing your Knowledge and awesome educational content you share with us.

Glam I could help
Very nice videos Mike!!!!! Thanks for creating them!!!
Thank you for sharing your knowledge
No problem hope it helped
Everyone Mike is the real deal! I took on installing a new RUR199 it was quite the project but with watching all the install videos from mike a few times i was able to install the unit no problem. He makes sense of the stuff i wouldn't otherwise understand such as the different venting. I was also able to give Mike a call and talk to him real quick about installing and picking the right unit for my existing water system. So THANK YOU MIKE! i am loving my new RUR unit!
Thanks!!! Your videos are really informative! I appreciate you responding to my email and fielding my questions! Super helpful!! Thanks again!
Dude, these are phenomenal videos
Thank you very much
Thanks so much! This really saved us in a pinch.
This is my wife
Thank you Mike!
Tanos looks good
Thanks Mike, I bleed mine through all the hot faucets before I plugged it in seams to be fine. But ill drain the 3 ports tomorrow to be safe .
Hey Mike, awesome videos you have. Very helpful. Thank you very much. How can I clean the condensate trap? Does it clean when I do the flush or is there something I can put in there to keep it clean? Thanks again.
Hey Mike! Love your videos they are extremely informative! New subscriber here! I did have a question. In this video you mention not to use regular PVC can you tell me why? Thanks Travis
Hi Mike, great videos and thank you for sharing your knowledge. I installed a Rinnai i90 Combi boiler. I need to use a condensation pump. The 2 wires provided in the boiler need to be connected to a condensate pump with normally open terminals. The pump I purchased has normally closed terminals. I connected the 2 yellow pump wires to the 2 boiler wires labeled "to condensate pump" and got a condensate error message. I disconnected the wires and the error message went away. Can you recommend a pump that is compatible with the i90 boiler? Thanks
Mike you're a lifesaver!.....Thank you.....excellent videos. I re-did my condensing drain line based on this video. I had a garden hose before.........One question. I had the error 25 so I cleaned out and redid the drain line as you suggested. My unit wont fire on single faucet call for hot water, as soon as I add a second faucet call for hot water the unit will fire and works fine....any suggestions?
What’s the maximum length of condensate tube can be to discharge the condensation from the tankless water heater? Thank you for all your videos
He mentioned in another comment that the pitch should be 1/8” for every foot length. Not sure if that helps you.
My RUC98i has been in service for about 6 years. We just had a very cold night in South Carolina and my unit will heat for about 2-3 minutes and then I get a code 25 and the water turns cold. How do I check the condensate trap and drain line for blockage. Everything is properly installed. Is this a simple fix that I can just blow out the trap and drain line? Thanks Jack
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!
awesome, thanks
Hey Mike! Thanks for all tje videos. Great tutorials. I have a question for you. I'm installing a rinnai tankless in my basement. I've got s wrll system. And I'm wondering if I need to install a thermal expansion tank? I don't think I do since it's tankless but the question has been on my mind. Thanks!
Mike - I have a Rinnai that I installed around 9 years ago. Occasionally the condensate tank will get alga in it and the water won't grow over the top baffle to the drain side, the unit shuts down. I just pull out the condensate tank, use a little bleach and I am good for a few more years. My question is, Can I put drain hose on the flush side in addition to the drain or does the condensate tank need some resistance to work properly?
Thanks Mike, how often do you need to bleed a RSC199 unit
Hi Mike, in my basement, I have installed 2" PVC exhaust pipe at 1/4" upward slope to exit 14 ' from the unit. How does the RSC199iN route internally the condensation drain water that back flows from the exhaust 2" PVC pipe into the RSC199iN and avoid having corrosion problems in the Rinnai tankless heater?
Hi Mike ..I have the newer RCS199ip ..with the condesate line do I need the neutralizer? If so do i install both the neutralizer and the condensate pump? TY
So you stub the condensate outside, what about freeze protection?
There is no way to protect that stub out.
I may be wrong, but open pipe allows bees, wasp, and other flying insects to get in and build nest like a muddobler
I have a ru199ip that codes out with 12, If I disconnect the hose going to the condensing trap and drain into a bucket it works perfectly. pressures are good, venting is good, parameters are set.The cvpvc is installed just like the one in your video. Any suggestions?????????
Thank you Rinnai Mike. I purchased a RU130IN any videos on that unit?
it’s the same as the RUR series video except no pump or pump piping. mike
Great Videos!!! more help than Rinnai. I keep getting a code 12 after a bunch of reading, I stumbled across air flow on condensate line, found excessive water in the trap that's normal, it appears to not be draining, its been flawless for 10 months. I removed ph filter, removed trap, cleaned out no more code 12?? however every three to four days, depending on usage code 12 pops back up system shuts down and trap is full again. I now have ph filter disconnected, to see if that the problem, is something else is going on? any thoughts???
What will this do to a septic?
So do you leave that small black drain unplugged forever? I was having issues with my heater and got code 25. I opened up that plug and left it open. I’ve had no issues ever since but when we use the hot water it does drip
Mike, I have a CU199i model just installed 8-24-22 and I’m getting a error code 25 which is my condensation pump switch is made. If I just unplug the 2 safety switch wires the code goes away the unit resets and continues on. I’m using a liberty pump LCU-20st which is made for condensation removal. How do I get this pumps safety switch to work with my tankless? Am I missing something obvious like a normal open or normal close.
My manual says the unit wants normal open (NO). Any insight would be greatly appreciated.
So you can just drain these to the outside without any issue?
I have two Rinnai units on the outside of my home in North, TX. With the extreme cold we are having, the condensate drain lines froze up on both units. Whoever installed these 5 years ago did the condensate lines with 1/2" pex. My plumber cut the pex to create a temporary bypass for the section that is behind the wall, but wondering if I should consider a more permanent fix. Any suggestions?
You could put 3/4” CPVC piping but there’s no guarantee that won’t freeze. If he cut a vent into it like on my videos you could blow sir or pour anti freeze through it
I got an error code 10. My house is not even 2 years old. There is a black 5/8 water hose line connected. It's just pushed on male fitting and the opposite side of black hose is glued into a 90 degree pvc fitting that goes into my wall. Outside the there is a pvc pipe that connects to a 90 degree fitting. This froze up and the pvc pipe in wall is froze up.
Can I drain the condensate water into a sink? If the sink is above the unit level, do I need a pump?
Can you train in to a sink the same way ac condensation lines usually drain in to sinks?
Hello, how do you clean up the condensation from a rinnai r75lsi. Thanks in advance.
so its fine to discharge the condensate into the yard?
Mike,my Rinnai Rl94 unit is leaking water from above the fan unit. I have been looking for a solution to no avail. What part would be leaking to cause this issue ?
Thanks for the video.Can a 1/2" condensate line that is significantly over pitched siphon water from the tankless trap during drainage? even if the condensate line is properly vented for air lock
The line should be pitched around 1/8” per foot
@@TheBuddylab thank you
When running out a wall in northern states (Ohio). Should I worry about freezing or what should I do to compensate for that? Should I create a p trap inside to prevent cold temps from entering pipe?
I’m looking for that answer too. Did you get any info on that rusty oh could share?
Thx for the info Mike! We just had a combi Rinnai installed in our basement... They have a condensate pump and drain line going outside... but it keeps freezing. We don't have a drain in the basement to feed it into...
Any suggestions on a solution???
Is there a sewer line at the ceiling they can put the pump discyinto?
Sorry that’s discharge into lol
@@TheBuddylab We have septic, and yes there’s sewer lines right by the unit.
Also when the boiler runs it makes a high pitched sound... this normal???
Thx so much for your time... the installers have been terrible!!!
@@petercerrato8447 you're gonna want a condensate neutralizer installed before you dump caustic water into a septic system.
For applications with a condensate pump - is there a way to utilize the safety switch on the pump to cut power to the Rinnai if the pump fails?
Yes there is a plug in the unit that will allow it
great video, thanks! FYI, there's a ton of low-frequency noise... sounds like somebody hovering over the microphone & breathing into it.
Hey Mike , Im not sure if this is the corrrect video for this question but i'm taking a shot. I installed ru1199in last season. Direct vent 3" exhaust and 3" intake and all has been good beautiful hot water forever with one issue that has happened a few times. I find water covering the collar of the exhaust vent. I know this is not good why is this happening and how can I remedy this. Thanks for any tips or advice.
So It turns out i did not seat the exhaust vent past the gasket inside the collar. I believe that now its fixed as i have reseated it and the pipe is sitting much lower in the black plastic collar. Thanks for the videos and this is the wrong video for exhaust venting ...sorry Hope this helps someone else down the road.
Do you recommend installing a condensate neutralizer before the condensate pump?
If it’s going into the sewer yes
@@ThatTanklessGuy if it’s going from inside of the garage to the outside and the outside happens to lead into a garden bed, will the condensate waste kill our roses?
OMG I just had a rinnai ru199 installed and they drilled a hole in the concrete and placed the pvc condensation pipe in it and put no t on it for venting , will I have problems . Please let me know I asked if that would cause a flood and they said no but your right bugs can get in the pipe . I haven’t paid them the second payment cause they aren’t finished
How about a neutralizer when going into the plg system. State of Ma .requires. Why not pvc ?
If you local code requires it install it. You can use PVC. CPVC works very well and looks better on the install.
Assume video . I like ur channel 👍
For Rinnai RL94eN outdoor national gas
what is the minimum size for the gas pipe ( blk pipe)?
Thanks for the comment I always run 3/4” pipe and use a full port ball valve and 3/4” gas flex. Mike
About how much water drain from the condensate tube from the unit?
Can I route my condensate drain to the basement sump pump pit? Is this condensate more acidic than A/C condensate?
About the same but a lot less
Hi Mike, I have a Rinnai RUR98 and its got a code 25 saying the Condensate Trap is full….I don’t know how to fix it and no plumber seems to want to touch the thing. Any suggestions or help?
Call me at 19042385349 today around 5pm eastern time and I will go over it with you Mike
@@ThatTanklessGuy for whatever reason my phone never notified me of the response to this video. Any chance I can call today if you are free?
My RU Sensei Propane unit only has a bleeder for the condensate. Do I not have to bleed the rest or how do you?
No a RU series only has to be bleed through the hit water side of the faucets. Mike
@@TheBuddylab Thanks Mike! One last question. I have a propane tank outside. Regulator on it and one right next to the house, I believe. Plumber didn't install one next to the unit, no Petro, however you spell it. Do I need to worry about this? Propane guy said one next to the house was just too bring up the pressure, I believe.
You are the fucking man. Thank you for this video.
😂🤣 smegma 🤣🤣
Love the videos!!
i was just going to say this
Can I tie the condensate line into the T&P?
NOOOOO that line need to be run separately to a drain or outside.
Any idea how much these actually condensate on average?
It all depends on the location inside, outside, basement, attic and the weather colder more hotter less I hope this helped Mike
What does a Code 10 on Rinnai mean?
Air flow problem
@@TheBuddylab my current set up doesn’t have a condensate trap. Could this be causing the Code 10?
You turn the water on and let it set for a month? Interesting
I have a code 10
What’s the maximum length of condensate tube can be to discharge the condensation from the tankless water heater? Thank you for all your videos
