Is there any kind of special fitting out there for literally tapping into a 4" drain? It's ABS, running in a side wall in the basement, almost completely surrounded by spray foam - there is about 1/3 of the pipe still visible on the top. It runs horizontal on the wall for about 15' right past where I'd like to put a sink. I'd almost need some kind of screw in fitting and I don't think they exist.
I know it's possible to carve out all the spray foam, but i was hoping there woudl be a simpler solution. I'm sure some hillbilly out there has drilled a hole in a drain pipe and jammed a 1.5" drain in it before.
