I am looking to put a variable speed motor on my Hayward Super Pump. I'm not sure what size I need though. My pool is around 28,800 gallons. I have to skimmers tied into one two inch pvc line that reduces to 1.5" PVS at the three way diverter valve. My main drain is 1.5" PVC coming into the other side of the diverter valve. I want to be able to turn the pool over at least 1.5 times a day. Is there any more information I need to figure this out? Thanks in advance guys.
