..right above where it meets the main? My mother bought a house and I am extremely limited with what she and my step father will allow due to stubbornness and money and the only available pipe to dump a half bath from the first floor is the FAI which the previous owner had buried into a wall for some strange reason. I want to cut the pipe before the elbow, close to the main, put a wye and dump the 3 inch from half bath into it, then connect a new FAI into the top of said wye and not bury it in a wall this time.
I will be using PVC for the half bath but am unsure of what the best option is for connecting to the snapped Extra Heavy 4 inch. Can sch 40 PVC connect to a hubless piece of XH pipe? Before looking like an idiot at the plumbing supply I figured I'd look like an idiot here. I just want to make sure first but I really can't think of a problem other than some obscure local code.
Thanks a lot. After doing commercial for 3 years its a pain in the ass to see 80+ yr old plumbing and have to fix it cheaply.
