trying to connect the trap for my shower to 1Â½" waste pipe. the trap was supplied with the "designer trays" 45mm shower tray.
the problem is that i can't find any 1Â½" pipe that will fit into the trap/compression joint. it is all a fraction too fat for the trap. i've tried to file a piece of polypipe but had to take too much off to get it to fit.
i've tried connecting to polypipe, marley (which used to be thinner than polypipe but not any more it seems) and mcalpine and none fit.
its definitely not 1Â¼" - the pipe is way too small and just rattles around.
anybody aware of any makers of thinner walled 1Â½" pipe?
