I have moisture gather on top of the hex adapter where the 2 " PVC vent stack goes into a 3" tee. The hex adapter has slots on top that are filled with water. There is no moisture on the stack pipe itself. There are copper hot/cold supply pipes in front, but they are not sweating either. What could be going on?
Additional information:
The bottom leg of the tee is for the toilet below, another arm goes at a right angle to the lavatory). 1/2 inch hot and cold supply pipes run in front. The wall cavity is on an internal wall.
The attached files show the top view with the slot in the hex adapter filled with water and the side view, with the supply pipes in front.
I run a hose through the stack on the roof, let the water run, but there was not leak detected.
