Efficient Filtration

As the filter traps dirt, the pressure rises. High pressure reduces water flow and strains your pump motor.

Actionable Steps

Reading the Gauge

Check your pressure gauge while the pump is running at its normal speed. Note the 'clean' pressure after every cleaning.

⚠️

Safety Warning: If pressure exceeds 30 PSI, turn off the pump immediately and check for closed valves or severe clogs.

Pro-Tip

If your PSI rises quickly (within 24 hours) after cleaning, you likely have 'live' algae that is too small for the filter to catch but large enough to clog it. Consider a Flocculant treatment.
