I am plumbing a new toilet. All the books that I have read have talked about connecting the closet flange to a 4x3 reducing 1/4 bend. However, the closet flange that I plan to use has a 3" socket (accepts 3" pipe") (it also swivels - which is a new feature, I think). So I plan on using a 3" 1/4 street bend from the closet flange over to the sanitary tee. Is there a problem with this? (note I am on the second floor, so 4" pipe is not an option) thanks
