New here. Appreciate all the pool wisdom. I have had a pool for 39 of the last 42 years in different houses. Every year I discover something new - usually as a result of a new problem. So this year the problem is the electical bill.
I currently have a Sta Rite 1HP pool pump serving a 20,000 gal pool operating 4.5 months per year.
Figure I can save kilowatts by changing to a WhisperFlo 3/4 HP 2 speed.(Could use the model number if available)
Is this a good move or is there a better one?

Pump is 65 feet from pool, elevated about 2.5 feet.
2 inlets; one return. All 1.5 inch ID

Thanks, Gary
