My vent pipe seems to be leaking quite a bit of water. I opened up the drywall and it seems to be coming from the seam where two pvc pipes join together. The amount of water seems excessive. Any thoughts? Doesn't appear to be coming from the roof but more like condensation.


Thanks!

Vent pipes, if installed correctly always should have a pitch to allow condensation to flow down into the sewer system.
I had a vent pipe leaking in my attic. I thought it was a roof issue and that the pipe wasn't sealed properly. What actually happened is that the vent stack got pushed down to where any condensation was trapped in the pipe rather than flow back down. No problems in the summer, but in the winter the pipe would freeze because it was full of water. As it thawed it dripped and one of the tee's was not sealed properly so it leaked there.
I am not sure if this is your issue but I bring it up for your consideration.
It's unfortunate that vent pipe isn't always given the same attention as drain pipes when assembling. Many assume it will never have to carry any water so they slap it together and forget about it.

At the roof it's a vent... below that a bit and it's a drain too.

Sure. Fix (rebuild) the joint.

Post a few photo's and ask your handiest neighbor/friend to look too.
If the rebuild is needed? That's not the job to cut your teeth on.

Thanks for the responses. I'm just amazed at the amount of water. I wrap the joint with a towel and it becomes wet in no time. I'm going to verify everything in the attic and then go from there. Thanks again!

Just to follow up my vent pipe wasn't glued at one junction and it was leaking there!


Thanks!

Well that's good. But where is this pipe?
If it's a vent, not a drain then the only water in the pipe would be condensation.
If you are getting a lot of water in a vent pipe then the pitch is incorrect.
