I recently got all new equipment installed for my pool, including a Hayward MaxFlo 1.65 hp VS pump. The company that did all the installation set up the pump programs and told me there should be no need to tinker with it. Reading the TFP forums has taught me a lot, including to be skeptical of pool companies so I wanted some reassurances from here. The current program is:
12AM-8M: 1800 RPM (at this level there is no filter pressure and the heater won't operate due to no flow)
8AM-10AM: 2300RPM, (at this level there is 5psi on the filter and the heater won't operate due to no flow)
10AM-11:45PM 3000 RPM (at this level there is 12psi and enough flow for the heater to work)
So my main questions are:
1) Is it normal for there to be no filter pressure and no flow to the heater at the two lower speeds.
2) If it is normal, is there really any benefit to running the pump for 10 hours with little to no pressure other than to keep the water moving.
3) It seems to me that running the pump from 10AM-11:45PM at 3000RPM seems like overkill. If I want to run the heater all day then I obviously need to, but I used to run it for four hours in the morning and four hours in the afternoon (after consulting the pool school) with my old one speed pump and never had a water quality problem.
Thanks for any help
