I'm not sure if it is enough work for a plumber be interested, but we need to make some alterations to an existing soil stack on the outside wall of a house in Reading. The wc is moving, and I've made a new hole in the wall for the waste, but it needs hooking up to the existing branch in the soil stack which will probably need to be moved up. I also want a basin waste added, which requires a hole to be drilled through the wall, and a 32mm waste pipe routed to a new boss on the soil stack. The current soil stack is in painted black, grey osma plastic, with push fit fittings which is fairly old.
