Waste Pipe (new appliance)

This pipe collects waste water from appliances. Alternatively, the waste may be fed to a hopper or an outside gulley. With gullies, it is necessary to terminate the waste pipe below the grid, but above the water level inside. Chessington Plumbers will carry out this work. The pipe should run downhill slightly along its entire length (6mm fall / 300mm length) and be adequately supported by brackets at regular intervals to prevent sagging.Fitting and connecting the waste pipe.Once you have figured out the way the pipe will run. make a check that there will be no obstructions like cables or pipes in the external wall. Also make careful measurements to determine the position of the soil stack outside.Drill through the wall using a bit of the same size as the external diameter of the new pipe. Insert a short length of pipe through the wall and assemble the external pipework to the gulley or hopper. DO NOT tighten the connections yet. Instead, move the new pipework to one side. To make the connection a number of different types of fitting can be used. A strap type boss is the easiest to use. Mark and drill the pipe with a hole cutter of exactly the diameter specified for the fitting you have. Place the boss over the hole, following the manufacturers instructions and fasten it in place. Insert the connector piece, which usually has a rubber gasket pre-mounted to provide a watertight seal. Connect to the soil stack and reassemble your external pipe run making the connections. A Chessington Plumber is experienced in these connections. Then, once the external waste has been completed, the pipes and fittings for the internal run can be made. Fit supporting clips at regular intervals on all pipework to prevent it from sagging. Job done. The size of plastic waste depends upon its use:21mm ? overflows, 32mm – hand basin, 40mm – bath and sink,110mm – soil pipe
