Maintaining a sand filter pump for a swimming pool is essential to ensure water stays clean and the system runs efficiently. Here's a practical maintenance checklist:

🧰 Weekly Maintenance:

Check Pressure Gauge:

Normal range is usually 10–20 psi.

If pressure is 8–10 psi above the starting level, it's time to backwash.

Backwash the Filter:

Turn off the pump.

Set the multiport valve to "Backwash".

Turn the pump on and run for 1-2 minutes or until water runs clear.

Turn off the pump again, set to "Rinse", run for 30 seconds.

Return the valve to "Filter" before restarting the system.
