Hello,
I see Screwfix sell pipe cutters that cut pipe up to 35mm or 42mm in diameter. The only pipes I can think of that size are 32mm and 40mm waste. Are these what you are supposed to use to cut waste pipe? I never knew that. I must confess I always used a (blush) hacksaw! Don't worry, I don't use it to cut barrier pipe! I have a proper cutter for that! If these do work on waste pipe, that would be a useful tool to have. Or is there some other 42mm pipe that I am not aware of?
Screwfix parts #27421 (to 35mm) and #61583 (to 42mm)
Thanks, Stephen.
