Considering 2 speed pump? Here's a cost comparison.

[larry2338]

I'm also considering a 2-speed pump and wondering if there is a substantial difference between brands. Is there any reason not to go with whichever brand of pump is cheapest? Are they all reliable? Why would I buy a Pentair 1hp 2-speed for $479.00 instead of this company's 1hp 2-speed for $335.00?

Dave:
Your premise is, at least for me, not valid.

My use of high speed is primarily for backwashing. When I used a hose vacuum, I would need it then. But now with autocleaners and a PoolBuster, the hose vacuum's been the cellar for 2 years.

I have solar panels and they work well with low speed. They ARE more efficient at high speed, but if the water is warm (89-90) why bother?

I sometimes use high to circulate the water more--to make the skimmer more efficient or distribute chems faster. But generally, low is JUST FINE.
