| Connecting HVAC drain in the side of the attic vent pipe.
I have a leak in my attic where my HVAC condensation drain goes in to the side of the sewer vent pipe in the attic.
The HVAC drain PVC has a small trap made from 4 white plastic elbows. The one elbow sicks in to a hole in the side of the vent pipe, and is leaking where it goes in the side of the vent pipe.
At this point, I have the HVAC drain pulled back, and can see that the pipe was just glued in to a hole in the side of the vent pipe. (I covered the hole to avoid any fumes in the attic.) I am guessing even rain water coming down the drain pipe could leak there.
How can I connect these, so they will not leak?
Thanks for the help! |

| first of all, the ac should not direct connect to teh vent. it is against plumbing codes. it is done all the time, but is still illegal. it is supposed to connect via an indirect receptor. basically this means it should drip into a trapped pipe/sink/etc. this is done to keep the sewer gases out of the HVAC system.

@optonline.net | IOW, splice in a trap. Then some combination of reducer(s)/female thread adapter to fit the drain pipe to the trap. |

Tybee Island, GA | There is a trap in the HVAC drain line. I am trying to re-connect this trap in to the side of the vent pipe.
Is there some fitting or connection to make it seal to the hole in the side of the vent pipe? |

Leander, TX | I believe the problem with the way yours is set up is that in the winter the trap can dry out and you get sewer gas into the system. If you want to connect it back like it was, I would use Plumber''s Epoxy Putty to seal the pipe into the hole. |

Is there some fitting or connection to make it seal to the hole in the side of the vent pipe? This what i did when the drywallers put a nail into my washer drain pipe. I did not want to take any drywall down if possible so what I did was grind some pvc pipe up. I made a paste using pvc cement and the ground Pvc. I took a putty knife and filled the hole up and let it dry. It worked good as new.

As mentioned, the way the condensate drain is piped is not code. However, if that's the only way for it to drain, I guess you don't have much choice.
What I would do, if there's room, is to cut the trap out and move it back towards the evaporator coil. Then, you can re-pipe to the vent so you use just PVC instead of a PVC fitting to make up to the vent. Then, you can seal the hole. If you can get a 90 inside the vent, that would be even better.
Another option is to pipe the condensate drain outside through the soffit down the outside wall into a pea gravel pit. |
