Frequently Asked Questions
What filter cartridge does the Hayward Star-Clear C500 use?
The Hayward Star-Clear C500 uses the PA50 (also sold as C-7656, 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 Star-Clear C500?
Smaller cartridges like the one in the Hayward Star-Clear C500 usually last 12 to 18 months. The clearest replacement signal is a filter pressure that won't come down after cleaning. Pleat damage (tears, channeling, permanent discoloration) is the other one. Either gets you a new cartridge, regardless of how old the current one is.
How do I clean the filter cartridge in a Hayward Star-Clear C500?
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 cartridge. 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.
