Swimming Pool Tips

Swimming Pool Information

The length of time a swimming pool pump needs to run for depends on a couple of different factors. The main two are, the amount of water a pool has and the size of the pool pump. The other determining factor is the condition of the swimming pool water.

How Long Should I Run My Pool Pump?

In this article, we are assuming that the pool water is in good condition. That the Chlorine, PH, and Total Alkalinity levels are all within their acceptable ranges. In Summer the total amount of water in a swimming pool needs to be filtered at least once every 24hours. In Winter the pump filtering time can be reduced to half.

Below is a chart that gives different pool sizes in liters, pool pump sizes, and sand filter sizes. Within the chart is the amount of hours to run a pool pump. Look at the pool pump itself to find out the kW rating. There will be a tag or a metal plate attached to the pump with the information stamped on it.
