Why does my pipe not fit into Multifit fittings?
Multifit fittings should accept most plastic and copper waste pipes manufactured to suit the UK market. Check that the pipe meets the minimum requirement of either 32mm or 38mm or 51mm internal bore. It may be helpful to chamfer the inside of the pipe to remove any burr. Continental size pipes can be connected using our: • DIN to UK Straight couplings: S28L-ISO, T28L-ISO, Z28L-ISO, or • DIN to UK Bends: MS4-ISO, MT4-ISO, MZ4-ISO.
