I have a Pentair Intelliflo variable speed pump. It is 3 hp (I think) and has 4 speeds. I think lightning may have fried it the other night during a bad thunderstorm, I have an electrician checking it out today. If it is fried, I was thinking of going with a cheaper 2 speed pump and possibly lower hp. All we ever use is speed #2 (1800 rpm) and speed #3 (2300 rpm). If I bought a 1 1/2 hp pump with 2 speeds would the low speed be close to speed #2 on my Intelliflo? My pool is approx 22,000 gallons. Thanks
