Suggestions/Recommendations

My 1½ HP single speed pump died and I replaced it with a 1½ HP Pentair SuperFlo VS. I have three timer options available. Currently I set it to run at 3000 rpm for two hours and at 1450 RPM for six hours. I've not set the third timer.

My Pool: 10k gal, plaster, 1½ Hp Pentair 342001 SuperFlo VS pump, Hayward CX 1300RE cartridge filter, Hayward AquaRite SWG w/T-Cell 9, Gulfstream HIE 110-R-A heatpump, Superscreen cage, Pentair Rebel pool cleaner, water temp 85, located in SW FL.

For the first two hours I run the VS at 3000 RPM to achieve initial morning skimming, and heat pump when needed to get the pool started for the day and then drop down to 1450 for the rest of the day (6 hours). I use the quick clean function when using the Pool vac weekly. I have not set up the third timer for use. My AquaRite w/T9 runs for 8 hours daily at 40%.

My question... As this is my first variable speed pump, I wonder what other VS users consider the optimum settings.

I am also curious as to the approx. GPH the VS might be pumping at these RPM. I have 2" plumbing and about 100 ft of head.

I don't think 8 hours is enough time to generate enough chlorine to keep your pool clean/sanitized. Most/many people run variable speed pumps 24x7. I do on mine. I run at 2000rpms for all of the day accept for 2 hours at 3000rmps to help the skimmers or if the heater is on it is also 3000rpms. If you SWG works at 1450 I suggest running that all day. Do you do your own water testing? I suggest the TF-100 test kit to see what your water parameters are. Check chlorine asap as I do not think you are generating enough with just 8 hours.

Jim,

I run about 5 hours at low RPM (just enough to open the flow switch on my SWG) and 2 hours at 2500 RPM to run mu suction cleaner. My SWG is able to generate enough FC in the 7 hours of run time set at 75%. I'm on a Time of Use plan, so I run at night to save on energy costs. I do run the pump at the lower speed when we swim during the day.
