Pool Turnover Calculator
Calculate how long one theoretical turnover takes at a known or estimated flow rate.
One theoretical turnover
6.7 hours
Turnover is a planning metric, not a guarantee that every gallon passes through the filter. Sanitation, skimming, hydraulics and bather load still matter.
How to use the result
Treat this output as a planning estimate. Verify the final choice using the manufacturer’s current manual and pump curve, the filter’s design-flow limit and the requirements of any heater, cleaner, salt cell or water feature.
Measurements improve the answer
Pool volume, actual pipe diameter, clean-filter pressure, equipment elevation and voltage all affect the final selection. If those inputs are unknown, measure them before ordering equipment or changing electrical service.
