I am shopping for a pump to replace a very old single speed that quit. My preference is a Pentair Superflo 2-speed, 1 HP. I was told by Pentair support that the speed on the pump is changed by a switch on the back of the motor. Since I want to run the pump at both speeds everyday, I want to be able to do that automatically via a timer or something else. Is there a way to do this? If I have to manually do this every day, I would rather spend the extra money ($300) and buy the Superflo VS. Any help is appreciated.
