Carl, since I put in solar panels, I was thinking of going with a 2 speed pump (just burned out my pump) I now have a 1hp jacuzzi. With the solar panels, the return wasn't as strong as before the solar panels. When I turn off the panels the flow gets strong. The pump is next to the garage that the solar panels are on the roof of. The pipes go up about 10 ft. My sand filter is 200lb hayward. What would you suggest? I like to keep my pump running 24/7.
