I recently purchased a home with a pool. It is inground size 40x20. I am trying to have the most efficient flow possible with my setup. There are 2 skimmer lines and one main drain line. All 3 are 1 1/2 inch. Then one single line is also 1 1/12 going into the pump. Should I make that 2 inch for better flow? I really have no idea what I’m talking about, it just seems logical to me. TIA for any insights.
