I'm replacing a rotten subfloor and toilet flange for a customer. Was going smoothly until I noticed that their piping is 3" Schedule 30 and all my new pieces are Schedule 40. Can somebody please recommend a coupling that will work to join these? Do they even make them? I had found a bushing to join them since the ID of both is the same, but thought using a coupling on the outside (less obstruction in the pipe even though it's minimal) would be preferred.
