End terrace, pretty standard house. I have a downstairs toilet at the front of the house with a macerator and pipes running under the floorboards out to the foul water drain at the back. I just spoke to a builder who says that as we're having decking all around the side and back of the building, he said we can just lay the pipe on the concrete path and have the decking over the top. Obviously then it'll have to be dug down into the main. Is that ok or does the pipe have to be buried?
