My mum has asked me to renovate her bathroom. The old suite is out and the wastes for the sink and bath are made from copper and jointed into the soil stack that is boxed in (in the corner of the room). I have measured these as well as I can with a tape and they appear to be around 32 -35 mm diameter, I will get an accurate measurement when I go back tomorrow with my vernier. My question is has anybody ever seen this set up before and is it possible to get a connector to fit on the copper and then I can work in 'normal' plastic? If they are actually 32mm will the standard push fit connector for wastes be OK or will there be a reaction between the copper and the rubber O ring?
TIA
