I'm considering replacing my current pump to reduce energy consumption costs and hoping to significantly reduce noise.

I've got 22k gallon IG pool with a DE filter and 2" PVC pipe. The pump is about 30' away from the shallow end skimmer and probably 60-70 linear feet of plumbing away from the main bottom drain and deep end skimmer (neither of which seems to get much suction). The pump also sits about 4' above the water line.

Right after the pump there is a multi-position valve that returns water to drive a Polaris cleaner. Regarding the normal returns, there is a single pipe that splits somewhere to feed 2 returns in the pool. That pipe also has a multi-position valve that allows me to feed water to 2 fountains if I choose. There is no spa. I've got the mineral springs salt water system if that makes any difference. If it matters, the current pump is at least 2 HP if not 2.5 HP but I can't confirm or get specs for sure until I get home tomorrow.

Hopefully this gives all the necessary info. Any recommendations?

TIA
