What should the filter psi be on a pool pump?

The filter psi on a pool pump typically should be between 10 to 20 psi, depending on the specific system and conditions. A pressure reading significantly higher than this range may indicate that the filter is dirty and needs cleaning or backwashing. Conversely, a psi reading that is too low could suggest a problem with the pump or a leak in the system. Regularly monitoring the psi can help ensure optimal filtration and pool maintenance.
