    Folks:

    Hoping to get a clear answer on if a clean out is required for a main line (toilet) on upper floors in a home. Depending on codes (e.g. IPC or UPC) and change of horizontal direction >45 or 135 deg., triggers a clean out but there is an exception in 707 "Excepting the building drain, its horizontal branches, and urinals, a cleanout shall not be required on a pipe or piping that is above the floor level of the lowest floor of the building."

    So am I correct that I do NOT need a clean out above the lowest floor?

    Many thanks!

    The cleanouts for toilets are for the lowest floor.
    The kitchen sink always needs a cleanout.

    Thank you very much for the clarification!

    I'm running a new horizontal line between joists and want the option for a hard ceiling.

    4" x 3" closet bend, -> ~4' to a downward 45 -> into a long sweep 90 deg. -> ~4' to the main stack. Short run... just 90 deg. of turn.

    So just to be clear... An upper floor main line (serving a toilet) with less than 45/135 deg. change in direction does not need a clean out, but a main line with a change in direction >45/135 deg. regardless of location, does need a clean out?
