Hi, is there an issue with having pool equipment 65 feet from pool water? This is for a new build 18x36' inground steel frame vinyl pool. Would you suggest going with larger pipes than 1.5" do help with the longer distance? Thank you!
Consider 2" suction lines, 2" on all equipment pad plumbing and 1.5" on return pipes. Or you can upgrade a bit and do 2.5" on suction and 2" on return. For your size pool 2" and 1.5" plumbing is plenty good.
