View Full Version : Mis-Reading the Code

07-24-2010, 10:21 AM
I'm looking at the CA Plumbing code and it says:

"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.
