How Long Should I Run My Pool Pump?

Although many people don’t realize it, a pool pump has a big job: circulating the water in the pool, along with the chemicals that you add, plus filtering out the impurities and organic matter to keep the water fresh and safe.

You don’t have to run your pool pump constantly, but you should run it enough so it’s doing the job it is meant to do. However, you don’t want it do run too much: these pumps use a lot of energy, which will increase your utility bill, and constant use may cause it to break down. You’ll be looking at pump replacement if it runs too much.

How Do I Figure Out How Long My Pool Pump Should Run Every Day?

  • Inground Swimming Pool PumpWhat is your pump’s flow rate? This is the amount of water that is filtered through your pump during a certain time period, such as an hour. The flow rate is listed in the manufacturer’s instruction booklet that came with the pump. It will tell you many gallons are filtered per minute or per hour.
  • How many gallons of water are in your pool? You’ll need this to determine the how many hours it takes all water to be filtered through the pump. Then, divide that by the flow rate (the number of gallons that are filtered each hour) and you’ll know how many hours it takes for all water to be turned over once. For example, a pool that holds 15,000 gallons of water with a pump that filters 2,200 gallons per hour will take nearly 7 hours to run all water through the filter once.

For many pools, you should try to have the water completely turned over at least twice a day, so many people run their pumps for about 12-14 hours, and some choose to run it overnight.

What are some other things that can affect how long the pump runs?

  • The number of swimmers that are in your pool. If you have an all-day pool party, then the pump should be set to run for longer than usual.
  • How long your pool is in the sun every day. If your pool just gets some morning sun, then the pump won’t have to run as long. However, if your pool gets sun from 12 – 6 p.m. every day, then you’ll have to adjust the running time.
  • The type of pool that you have. Swimming pools will usually cycle all of the water in the pool at least once in less than six hours. A wading pool would probably cycle through for less than 1 hour.

If you’ve realized that your pump is taking too long every day to clean your pool, you may want to increase the turnover rate by buying a larger pump.
