I’m looking for help on a new above ground pool pump. We had a 1.5hp 2 speed Hayward pump that was working well. A few years ago we installed 25 -12ftx2ft solar panels on our 2 storey garage. However our yard is tiered and the garage is on lower level. Pool is on higher level. Pump is on far side of pool so has to run through tubing all around 21 ft x 54” pool then up about 10ft to garage roof. The pump we had was working well for a couple years but last year started sounding louder so we took it in and they said it had a bad bearing. Quoted us same price of a new one to fix. So here we are looking for a replacement. My question is do we need something else? Did we wreck it since we added the solar panels? It would run on low and heat that pool in a few days. If ran on high it wouldn’t heat as it ran through the panels to fast. But i don’t want to buy something underpowered either? All this talk of head pressure etc is over my head. 🙈 I have tried to understand
