Hi
I'm building a side garage and need to move the downpipes and drain in the picture about 1m to the right. The large downpipe is rainwater and the small one is the kitchen sink. The above ground part is straight forward. Below ground it drains into the old clay pipes. As it's so close I also want to drain the new garage roof into it. Is it best to cut a section out of the clay pipe and convert it to pvc using those rubber adaptors? What fitting would I install in the PVC section so that it can take two 110mm feeds?
