Hi, we have moved our upstairs bathroom so need to put a new soil stack on the outside wall. In the place where we want to put it is a rainwater pipe with a "bucket style" opening at the top, (sorry I don't know the correct term), because it is a flat-roof property so it catches the water from the gully on the roof into the bucket type opening and goes down the pipe.
Our rainwater and sewage all join to the same area underground, so would it be possible to combine our rainwater and soil stack into one pipe? Rather than having that rainwater pipe plus a new soil stack pipe next to it too.
So basically we want to replace the rainwater pipe with a soil stack with the "bucket style" opening on top. So any smells come out of the "bucket" above the windows, but also the rainwater still flows into it from the roof. So both rainwater and soil will go down the one pipe and under the ground.
Is this pipe combo allowed? Or do they have to be kept separate above ground?
Thank you very much for any help.
