To clean your pool pump filter, turn off the pump and release the pressure from the system. Remove the filter according to your model's instructions—sand, cartridge, or DE filters require different steps. For sand, backwash the filter. For cartridges, rinse with a hose and soak in a filter cleaner if needed. DE filters should be backwashed, and the grids cleaned with a hose. Reassemble and restart the pump, checking for proper operation. Always refer to your specific filter's manual for the most accurate and safe cleaning instructions.
