First of all, a pool pump should be used on a daily basis for proper circulation and cleaning of pool water. One cannot fix this time, as it might have to work more if the pool was overused during the day. An average of about 8 hours is sufficient in routine. These days we have pool calculators also for monitoring the time of the pump usage. It doesn’t require the pump to work for 24 hours a day, but to use it once every day is important. If the pumps are used regularly then it increases efficiency and helps in adding life to your machine., but on the other side overuse is never recommended.
