Frequently Asked Questions
What filter cartridge does the Waterway Front Access Skimmer use?
The Waterway Front Access Skimmer uses the PWW50P3 (also sold as 6CH-940, 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 Waterway models in the same series use a different number of cartridges than others.
How often should I replace the cartridge in my Waterway Front Access Skimmer?
Smaller cartridges like the one in the Waterway Front Access Skimmer 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 Waterway Front Access Skimmer?
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 Waterway Front Access Skimmer runs 2 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.
