Metric to standard plumbing

Fudsey · May 24, 2018

I have a question and maybe some of you plumbers can answer for me. If 32mm = 1.25984" will this not connect to standard 1.25" plumbing? If PVC prep and glue soften the pipe, will it not go together and seal? Please help me to understand. Is the difference too much?

Thanks

I don't know if it's too much, but I've sanded down pvc before to make it fit, but that wasn't a pressure rated setup. But they also sell adapters at brs and coralvue.

Funny thing is, the BRS adapters go from 32mm to 1" which is strange (haven't checked Coralvue). Why not 32mm to 1.25"? This would mean I would need 2 adapters to change 32mm to 1.25". I may just do what you said and sand it down to get it to fit. This will be my drains so no pressure to worry about.
