I haven't switched out my 1hp Max E Glas 2 pump for a new VS yet, but was ready to get the Pentair Intelliflo 10118, but then I just saw the Pentair 342001 SuperFlo VS Variable Speed Pool Pump which is a few $$ less. I am going to install Pool Solar heating panels, and want to know what pump will be more economical for me. I will also be running a Pentair legend cleaner that is currently running on a Booster pump. The suction Pipe to Pool Pump is 2" and the return line from the Filter to the Pool 1.5". My Pool is only 13,000 Gallons and 5ft Deep.
