The PL-122 was the original Polylok filter. It was the first filter on the market with an automatic shut-off ball installed with every filter. When the filter is removed for regular servicing, the ball will float up and prevent any solids from leaving the tank. Our patented design cannot be duplicated. Ideal for residential waste flows up to 3,000 gallons per day (GPD). (this product is the blue replacement cartridge only)
