    Default Mis-Reading the Code

    I'm looking at the CA Plumbing code and it says:

    706.1
    "Changes in direction of drainage piping shall be made by appropriate use of approved fittings and shall be of the angles presented by a one-sixteenth (1/16) bend, one-eighth (1/8) bend, or one-sixth (1/6) bend, or other approved fittings of equivalent sweep."

    I can't figure out why a right angle is not included in this list. Are there no 90 degree bends in drain pipes? Thanks for any help.

    You would combine two 1/8" bends.

    A long sweep 90 is equivalent, the same as an 1/8 bend and street 1/8 bend put together.

    Of course there are, but the actual application determines WHICH 90 can be used.
