    The 2012 UPC states:
    "UPC - 707.4 Each horizontal drainage pipe shall be provided with a cleanout at its upper terminal, and each run of piping, that is more than one-hundred (100) feet (30,480 mm) in total developed length, shall be provided with a cleanout for each one-hundred (100) feet (30,480 mm), or fraction thereof, in length of such piping. An additional cleanout shall be provided in a drainage line for each aggregate horizontal change of direction exceeding 135 degrees (2.36 rad)."

    My question is, does the turn into the cleanout count at part of the 135 degrees? Example, if you have a straight run of pipe, and a floor cleanout, does the 90 degree turn up to the cleanout count in the 135 degrees?

    The cleanout in a horizontal run would often be made with a wye, but in any case the allowed radius of turns is referring to change of direction in flow, not the normally dry section of a cleanout.
