water leak from the cap of PVC pipe


What's the purpose of a caped pvc pipe sticking out from the basement ceiling? I just noticed that there is slow water leak from the cap. It was raining. Does the rain have anything to do with it?

Future water line to ???? Raining wouldn't have anything to do with it unless you have a leak that will let rain water in

The cap might not have been glued on properly.

Do you have a rough-in for a future bath? thats common when they are done RIGHT to leave a vent in the ceiling. It's easy to fix it, drill a hole in the cap (it may have a lot of water in it) drain the water out, cut off cap and glue new on on.

Yes, we do have a rough-in for future bath. That may be it. Is it normal to have water accumulated in the vent?
Thanks.

If it is a vent, the cap may not actually be glued on. The reason for the water may be condensation.

Thanks much for the advice. You are exactly right! The cap was not glued. I easily pryed it open. There were a bucket full of clear water. Am I better off leaving the cap off? I assume air flow will prevent future condensation.

I really don't know. All I see is a PVC pipe sticking out from the basement ceiling with a cap on. Does anybody know the answer?

Sounds like a vent for future plumbing. Bush it down to 3/4" and put a boiler drain on it. When or if you decide to connect to it drain off the water. Or you can cap it on the roof. But be sure no active vents tie onto that line

So, the water is from the roof, not from condensation?
