One way to keep control of the time you run the swimming pool pump is to run it several times a day for short periods of time. If you want to activate the pump once a day, start with six hours, but never go lower than five hours, especially in the summer. If your pool is in constant use, you may need to run the pump for up to eight hours per day, frequently checking the water clarity and chemical balance.
Tip. 1  Set the cleaner pump, if your pool has one, to operate within the hours of the pool pumpâs operation. 2  Set the cleaner pumpâs timer in the same way you set the poolâs pump timer. 3  The swimming pool pump should operate 8 to 10 hours a day in the summertime to turn the water..
