The lead pipe that connects to toilet flange is cracked .this is connected to a two and a half copper pipe comeing from the t for the drain .I am trying to convert flange to pvc ,is it possible to connect 2 and a half inch copper to 3 inch pvc ? I was in home depot and they had that rubber clamp but only to go from 3inch to 3 .I already cut out the old flange with saws all through copper pipe .they didn't have the lead type either .any suggestions on either type of fix is appreciated.
Thanks steve
