    I have to connect the UPVC pipe to the ground. There's a connection of sorts there already. The rubber gasket there has perished but I don't seem to easily find a replacement. Even if I did, the old UPVC pipe I have doesn't fit tightly in there and presumably never did. My question is, does...

    soil pipe connection

    Hi all, is there a way to connect a new toilet into an existing horizontal run? The problem is, due to the levels it can only connect horizontally and not from the top of the pipe. Is it ok to use a standard branch connector in this way?

    TL/DR: Can I have a bend of 90 degrees in the dry section of a 4-inch soil vent? Hi. I am renovating a small bathroom.
