I apologize for the confusing post. The Return line is a single 1.5" line into the ground that supplies 3 return jets. I also have a single 1.5" line dedicated for the Polaris pool cleaner booster pump. The suction line is 1 main drain and 1 skimmer both in 1.5" piping. Sorry for the confusion. I plan on replacing the suction piping on the skid to 2" when i plumb the new pump to reduce head loss through fittings. Thanks for the help
