I am converting my garage to a utilty room and i need advice on drainage. A washing machine and sink will drain via a 40mm pipe through the outside wall at 50mm above ground level. The nearest drain is the access chamber which is 90 degrees from the wall opening at a distance of 8 metres. Is it possible to use a 40mm pipe from the wall opening to the access chamber at the correct fall and cement the pipe into the access chamber wall. If so what would i need to lay the pipe on and cover it with? (decking will be built over the area in question). If this is not possible what is the easiest way (and cheapest) to drain the room?
