Getting ready to begin plumbing my pool. I have a 20 x 40 with 2 skimmers, 2 main drains, 2 returns, and 2 step jets. My pump is 1 1/2. How would you plumb it and what size pipe would you use? I am planning on running the md to the pad and two lines for my skimmers. I was planning on putting a t in near the eq pad for my skimmers but my concern is that one would have more suction than the other. Should I do the same for my returns? Please let me know your thoughts....
