Hello: I have water leaking down through the attic vents and white PVC vent pipes. What is the best way to repair these leaks? Can repairs be made from inside the attic? Should the vents be replaced (they are plastic)? Thank you!:(

My basement was roughed in for a bathroom. I finshed the bathroom a few years ago and now I want to add a wet bar. Out of the concrete floor are two 2" pvc pipes 1 is going straight up to the ceiling (I assume that is the vent pipe) and the other comes up about 2 feet and connects to the vent pipe....

I'm adding a shower to a basement 2 piece bathroom. Under the concrete is cast iron drain pipe. Above is ABS vent pipe which I'd like to tie into. Should I use 4" PVC or ABS drain pipe? This house is in Alberta Canada.

I recently began to remodel my laundry room. I wanted to move the washing machine 3 ft from its current spot. When I removed the sheet rock I found that the vent pipe is between the current washing machine drain and where I am moving my washing machine. I wanted to avoid breaking into the slab....
