    can someone tell me how many toilets can be drained to a 3" abs pipe before the pipe has to be sized up?

    pipe size

    3 on 3", but once you add a fourth toilet it has to be increased to 4" at that point. Once you increase to 4" you can put more toilets on it than you probably need, or can use.
