Frequently Asked Questions
What filter cartridge does the Pentair Clean & Clear Plus 520 use?
The Pentair Clean & Clear Plus 520 uses the PCC130 (interchangeable with C-7472). Confirm the correct quantity in your owner's manual - the filter housing may also have a label indicating the part number.
How often should I replace the cartridge in my Pentair Clean & Clear Plus 520?
The Pentair Clean & Clear Plus 520 uses a 130 sq ft cartridge, which most homeowners replace every 12-18 months under normal residential use. Clean it every 2-3 months by rinsing between the pleats, and deep-clean quarterly with a filter-cleaning solution. Replace it when cleaning no longer brings the pressure back to baseline.
How do I clean the filter cartridge in a Pentair Clean & Clear Plus 520?
Turn off the pump and release pressure from the filter tank (open the air relief valve) before opening the housing. Remove the cartridges (the Pentair Clean & Clear Plus 520 uses 4) and rinse thoroughly with a garden hose, directing the stream at a 45-degree angle between the pleats. For a deeper clean, soak overnight in a pool filter cleaner solution, then rinse completely before reinstalling. Never use a pressure washer - it collapses the pleats and permanently reduces filtration.
