So I have 1 1/2" plumbing on a 46k gallon pool. I have two suctions lines / skimmers and also two returns. I've been worried about this 42 approx GPM max i'm reading about 1 1/2" pipe. My question is can I actually push double that since I have the 2 return and suction lines? Hoping I can turn over the water in about 10 hours.
