Proper Pool Run Times

The country is into the hottest two months of the year- August and September. In addition to the heat, heavy seasonal rain also affects your pool and its chemistry. For these reasons, this should be the time of year your pool is running the longest.

Let me try and explain some of the methods behind run time decisions. The proper run time required varies with each pool due to use, hydraulic design, and filtration system. The purpose of run time is to circulate the pool water long enough to “turn over” the volume of water in a pool (have all the water pass through the filter) at least once per day. Current code requires systems to be designed to turn over the pool water at least once every 12 hours in residential pools.

So if your pool was designed to the minimum standard you would need to run your pool 12 hours a day to get all the water through the filter once. When heat and rain increase you would need to increase your run time to get more than one turnover per day to help handle the extra filtration needs that most summers present.

Luckily, most systems we see are designed to turn over the pool more quickly and have large enough systems to handle greater flow rates. For example, typical Florida pools turn over in 8 hours by design. Therefore we can come up with some general rules of thumb for run time assuming an average pool with an 8 hour turnover rate.

The Rest of Winter

8 Hour Run Time


9 Hour Run Time

10+ Hour Run Time

Other factors that will affect run time: Heated Pools, Under or Oversized Equipment, Dirty Filters, Poor Circulation, Usage, Water Features, Spas, Pollen Season, and Clogged Lines.

For our clients on service, we adjust your run times throughout the year based upon your system and its specific requirements- no need to worry about it. If you have specific questions about proper run times for your pool please contact the experts at Pool Troopers, we’re happy to help.

Special Note:
If you have recently added a variable speed pool motor to conform to the new Florida Energy Law and are now running your pool on a lower speed setting to save energy you will want to run your pool much longer. Remember, cutting the pump speed in half requires twice the run time to get the same turnover rate. Half the run speed only consumes 1/4 of the energy, so you save money and use less energy- just don’t forget to increase run times! (Pump Affinity Law)
