Do not use a pressure washer; high-pressure spray permanently damages the pleat media. Continue until the runoff runs clear. Reinstall the cartridge, secure the filter head with the locking knob, open the air relief valve, and restart the pump. Note the pressure as the clean baseline for future cleaning decisions; a rise of 8 to 10 PSI above that number signals cleaning is due.\u003c\/p\u003e\n\n  \u003ch3\u003eDeep Cleaning and Cartridge Replacement\u003c\/h3\u003e\n\n  \u003cp\u003eSoak the CX500RE cartridge overnight in a pool cartridge cleaning solution at season opening and midpoint to remove oils, sunscreen residue, and mineral scale that routine rinsing leaves behind.

There is no multiport valve, no backwash port, and no drain line required. Routine cleaning is done by removing and rinsing the cartridge by hand.\u003c\/p\u003e\n  \u003c\/details\u003e\n\n  \u003cdetails\u003e\n    \u003csummary\u003eWhat does the built-in check valve do?\u003c\/summary\u003e\n    \u003cp\u003eThe check valve prevents pool water from draining out of the system when the cartridge is removed for cleaning. This means the pump strainer basket and plumbing stay primed during cartridge service, and no re-priming is needed when the filter is reassembled and the pump is restarted.\u003c\/p\u003e\n  \u003c\/details\u003e\n\n  \u003cdetails\u003e\n    \u003csummary\u003eCan the filter head be rotated after installation?\u003c\/summary\u003e\n    \u003cp\u003eYes. The filter head is designed to rotate so you can orient the pressure gauge and manual air relief valve in any direction.
