vent pipe shouldn't have any water in it. Maybe you have a leak where
it comes out of the roof..

Discovered a drip on outside of vent pipe in second floor bathroom that
eventually wore a hole in the ceiling. Replaced the vent cap and drip
seemed to go away for a while. It soon returned and I had a roofer check it
out and he put on another vent cap. Drip has returned again after a couple
of weeks. Any ideas on what to do next would be appreciated. I need to fix
the ceiling but want to fix the drip first.
