When it rains, I am getting a leak of water at a vent pipe union where 4
pipes meet. Here is a bad drawing. The 'x' represents the union. Where
the pvc pipe from the roof meets the 4-way fitting, (just above the X) I am
getting a leak. It's not running down the outside of the pipe. The water
seems to be coming from within the pipe and leaking out the top joint.
|| to bathroom
Any idea why this might be happening. The toilets and sink seem to vent ok.
Is there anyway to fix this?
Thanks for your time. sorry for the bad drawing.
