Just planning here. I will eventually run a 3" drain line to a vertical cast iron stack in the basement. The basement stack has cast iron plumbing above it for a bathroom and the goes through the roof. This plumbing is well supported, but I plan on providing more support before cutting the stack.
After making sure there is tons of support for any pipes above, I'm going to build a soffit around the C.I. stack and attach riser clamps to it above an below the cut.
I'll then cut a section of pipe out using snap cutters. My plan is to use a no hub wye fitting 3 x 3 x 3 and fit it into a street 45 to head vertical and pick up the dwv. Or is it better to just use a 3 x 3 x 3 pvc fitting with two no hub adapters?
Any problems with doing it this way? I know things can go wrong, but I assume that if I properly support all the pipes I can use a no hub fitting to connect pvc to my cast iron.
Or do I need to consider getting a cast iron wye fitting, pounding in oakum and then sealing over it with liquid lead?
thanks for the advice.
