<p>The plumbing drainage coupling member (10) has a manifold (40) from which three fixture connecting portions (20, 30) and (42) extend. Each of the fixture connection portions (20, 30 & 42) has a respective inlet (21, 31 & 41) connectable directly, or by pipe, to an outlet of a fixture, such as washing tub, sink, bath or shower tray. The manifold has outlet (47) connectable to a drainage pipe. A computerised method of producing the coupling member includes the steps of entering plumbing requirements into a computer so as to design the plumbing drainage coupling member; and using an output from the computer to drive a production method so as to produce the coupling member.</p> |
