My pool gunite is complete, and am awaiting coping and tile work this week. I am acting as my own contractor and am getting limited help from the person that I am purchasing equipment from.
The roughed-in plumbing consists of the following:
1. Two main drains plumbed to single 2" line.
2. Two skimmers each with 2" line stubbed out.
3. Four 1-1/2" returns that are tied together in a single 2" loop around the pool.
My questions are:
A. Should the skimmers have separate 2" pipe runs back to the pump, with a valve for each, or tied together right before a single valve?
B. The main drain line run 2" back to the pump?
C. Is a single looped 2" return line adequate? I read that some pools use separate lines for each return?
