I'm having an impossible time trying to find out the flow rates of my pump. I have a Swimpro Voyager 2 hp, 2-speed pump. High speed= 2hp@ 3450 rpm. Low speed= .25 hp@1725 rpm. I also have a Hayward H-series 150kbtu heater (not sure if that restricts the flow rate). I've searched everywhere I could think of online, with no luck. I realize that my plumbing comes into play, but I can't even find a chart with various head calculations. Nothing. Bottom line is, I'm trying to figure out if I can just run my pump on low for 12 to 14 hours per day. High speed just seems crazy powerful, and wasteful. Any help would be much appreciated
