Proper condensate drain piping on a Navien tankless.

I cannot stress how important it is to properly drain the condensate from a tankless heater. The vent is extremely important in the piping to allow the condensate to drain freely.
Please follow your local codes on how to neutralize the condensate, but if you need to use the Navien condensate drain kit.
Here is a list of the fittings you will need for the near tankless piping,
1/2" CPVC plastic female adaptor (not metal)
1/2" CPVC tee
1/2" CPVC St. ell X 2
1/2" CPVC ell and piping

We just had our first big freeze of the winter in the PNW and the discharge protruding outside my house froze up. (now it's insulated) Didn't realize until after I got out of the shower. Thanks to Mike I installed my indoor Rinnai tankless with the air vent in my relief line and it worked perfectly, preventing condensate from backing up into my unit. A little mess on the floor but no real damage done. Thanks Mike!

I installed a Tankless Rennai in my gut renovation. Worked great for about a year then stopped working.. the Internet said something about vent on condensate line. I didn't have one because i believe the manual didn't say to install one. Put one in working for 3 years now. Great video thanks

Great informative videos explain NAVIEN always needed some thing like this.

Mine doesn't have that. It was installed professionally and now has been error ing out after 8 months. I see rust inside the unit and they have been out many times to fix but it's still has a ignition error. Do you think that is my problem?

[@tonymc3817]

Do ya need to glue the fittings all together or van ya just press them in tightly for future removal and reuse, if possible

Was wondering the same thing lol

Hi, I am a plumber and I work in California, sometimes when I come to a problem with a water heater, I see that from the bottom of the heat exchanger there are drops similar to condensation and which sometimes drip and destroy other parts, I have a question, what can cause them?

[@therealSIRBOOM]

How do you convert the condensate to CPVC when the tankless has a barbed outlet for flex pipe?

I have a problem with my tankless, Renee code 38
