Pool Filter Pressure Too High — San Francisco, California
When the pressure gauge on your pool filter reads 8–10 psi above its clean baseline, water flow drops and the pump has to work harder, which shortens equipment life and leaves the pool poorly filtered. Common causes include a clogged filter cartridge or dirty DE grids, a closed or partially blocked return valve, and calcium or oil buildup inside the filter tank. A pool technician can backwash or deep-clean the filter media, inspect the multiport valve and internal laterals, and recalibrate the system to restore proper flow.
