My original Hayward Sta-rite 1-speed 1.5hp pump has bit the dust. One problem that I've always had with this pump was what might be considered cavitation. When using my suction-side vacuum from my dedicated suction port, I would have to have at least one skimmer valve open to bring in enough water to not run the pump dry, however this affected the cleaning effect of the vacuum. So I think this might have been caused by my pump being too powerful. None the less, I'm looking for a new pump now. I'm looking at the Pentair SuperFlo 1HP 2-speed, but I want to make sure this will be enough umph considering the distance from my pad to pool. Specs below:
Pipe size: 1.5"
Filter: 24" sand (Triton II TR-60)
Suction lines: 4 (2 skimmers, 1 main drain, 1 vacuum)
Distance from pad to closest skimmer: 35'
Distance from pad to main drain: 50'
Distance from pad to furthest skimmer: 65'
So given the above, would ya'll agree that the 1.5hp might have been overkill and that a 1hp would be more than enough? It's the way I'm leaning now, but I'd hate to under-power my setup.
