    Ah Mike dont you just wish plumbing were that simple guy?

    Venting is not just fixture units connected BUT developed lenth of pipe and fittings.

    For example I could run 8 FU’s on an 1-1/2 line BUT only for 30 ft BUT I would need a 2″ line to go up to 170 ft.

    Did you now depending on what type of toilet you have how many fixture units it is rated at?

    For example a close couple tank and bowl would be 4 FU and a flushometer type would be 6 FU..

    Why dont you invest in a local code book rather then guessing?
