Minimum Pressure

[tampatony]

Hello all,

I have a 13,300 gal in ground pool with a Sta Rite System3, model #S7MD60 DE filter, 60 sq.ft filtration area. I am trying to cut the cost of operating this filtration system. I would like to replace my electric pump with solar power. Disregarding the cost/benefit considerations for now I have the following questions:

1. what is the absolute minimum pressure required to effectively filter the water.

2. How many times per day do I need to cycle the water?

Thanks for your help.

For a residential pool, you want a minimum of one turnover per day, two is better. One turnover only processes about 42 % of the water, whereas two turnovers process about 84 %.

If you are relying on solar, then you have to determine the available pump run time based on how much sun you get. Then you divide the total number of gallons you want by the amount of time the pump will run to get the pump flow rate.

There is no minimum pressure requirement. The maximum pressure for that filter is 50 psi. The minimum flow rate is 20 gpm and the maximum flow rate is 120 gpm.
