Number of turns in a trap drain
I have a question on plumbing code - we live in California so I don't know if there are any unique requirements here.
We are remodeling our kitchen and the sink has a 1 1/2" trap drain. In the plumbing of the trap drain, there are currently 2-45 deg turns between the trap and vent stack. By adding an one more 45 deg turn we can eliminate the need to go through the back of 2 cabinets. The plumber has said that it violates code to have 3-45 deg turns in a trap drain. I can't really find any code that mentions so I'd like to get any pointers here.
