Okay........I cut a hole in the wall behind the kitchen sink and found the leak at the bottom of a "T" fitting where the drain connects to a vent pipe going up to the roof.
Can anybody please tell me how I can fix this leak? As you can see there is a 45 degree elbow clued into the line very close to the top of the "T" which seems to complicate the situation a bit.
Any advice would be highly appreciated......I'm a poor home owner who cannot afford to hire expensive plumbers......please, can anybody help me? I'm happy to do the work but I just don't know the tricks of the trade
