I'm installing a new drain for my shower, and I'm having some trouble working the drain pipe around some joists to the horizontal pipe leading to the main waste line. I have 2 questions.
#1 how far can the outlet portion of a p trap be rotated? See image below #1 is the nomal installation I see and I have seen some done as in #2. My tight situation would require #3, almost doubling back. Would this be a problem?
#2 after leaving the outlet of the P-trap the waste pipe will connect with a horizontal drain pipe that leads to the main house 3" drain. The issue is when running a drain horizontally, I know you must have 1/4" of drop per foot. Is there any limitation on the severity of the bends over the course of the horizontal line. In my situation a 90 bend would "work" but would this severe turn slow down the drain? Would 2-45s be a better solution?
thanks in advance
