I have one 1.5" line from skimmer to pump and one 1.5" line back to pool which feeds 2 returns. I plan to replace 14 year old 3/4 hp pump, 36 sf DE filter and add an SWG. The new pump, filter and SWG are all 2" so I would like to plump everything on the equiment pad with 2" pvc. Will I be able to do this since I only have one 1.5" intake line?
