Frequently Asked Questions
What filter cartridge does the Hayward SwimClear C5025 use?
The Hayward SwimClear C5025 uses the PA131 (also sold as C-7494, all the same physical cartridge). Confirm the quantity in your owner's manual or by counting the cartridges in the housing when you open it up. Some Hayward models in the same series use a different number of cartridges than others.
How often should I replace the cartridge in my Hayward SwimClear C5025?
131 sq ft is mid-size for a pool filter, which translates to about 12 to 18 months of service in typical residential use. Hose-rinse between the pleats every two or three months, soak in cleaner once a quarter, and replace the cartridge when cleaning stops bringing pressure back to baseline.
How do I clean the filter cartridge in a Hayward SwimClear C5025?
Turn the pump off and bleed the pressure from the filter tank (open the air relief valve at the top). Then open the housing and pull the cartridges. The Hayward SwimClear C5025 runs 4 cartridges; if any one of them is dirty, the others are too, so pull all of them. Hose them down at a 45-degree angle between the pleats, working top to bottom. For a deeper clean every few months, soak in a pool filter cleaner solution per the product's dwell instructions, then rinse before reinstalling. Don't use a pressure washer. The high pressure tears pleats permanently.
