Macerator Waste Pipes for Fitting Shower and Toilet

by LoisLayne » Thu Nov 08, 2018 5:47 pm

Greetings all, I'm hoping somebody can help me before I call up the uniflo engineers and look dumb!

I am fitting a shower and toilet to a uniflo 4 macerator. It comes with a 22mm non return elbow and 22mm rubberised pipe that I suspect will connect to 22mm plastic pipe.

My question is, can I step the pipe up to a larger one from the 22mm or will this cause an air lock problem? My intention was to use some kind of 22mm to 35mm non return convertor?

Thanks in advance!
