So I have a spa (~4500 gallons) with a Hayward Tristar single speed pump (2.7 THP, 2.0 FRHP -- which HP do you report by the way?) and the pool guy who used to take care of the spa said that the ideal pump run times were around 6 hours in winter and 9 hours in summer.
Does that seem right to you? Seems a bit high. What would you expect a pump time would be for that type of setup? I realize it depends upon flow rate achieved, etc. The spa is around 30 feet from the pump by the way.
Would installing a flow meter help give me an approximate pump run time?
