Time requirements for pool filtering vary from home to home due to differences in pool volume and equipment, the amount of use and environmental factors. As a general rule, one complete water turnover every 24 hours will provide adequate filtering for a residential or a small resort swimming pool.
The average recommended running time for the swimming pool filtration system is about 8 hours in summer (heavy use), and about 4 hours in winter (hardly any usage). The annual total pump operating time is about 2200 hours. 75% of all residential pools use a standard 1HP, 240 volt (single phase) AC pump (Fig 1) consuming around 2000 units (kWh) per annum.
