I have a few questions regarding pool pump replacement. My current setup is as follows. 25k gallon fiberglass pool with a Sta-Rite P2R5AE-124L pump pumping through a Triton TR-60 24" sand filter with 3 returns through 1.5" piping(suction piping is also 1.5").
I'm looking at either the Hayward SP2607EE, the SP2605X7, or the Pentair Superflow #348022. Im trying to stay as efficient as possible without undersizing
1) Without knowing my exact Total Head of Water should i go with the larger pump?
2) Any other Pros/Cons of Hayward vs. Pentair
3) The reason i have chose the pumps is due to the limitations of 1.5" piping with i have been told changes the efficiency/performance of the pump.
I hope i have provided enough information
Thanks
