Ask question about this product



The PL-122 was the original Polylok Filter. It was the first and still to this day the only filter on the market with an automatic shutoff ball installed with every filter.

Installs easily in new tanks, or retrofits in existing systems. Filters up to 1500 gallons per day (GPD).

When the filter is removed for regular servicing the ball will float up preventing any solids from leaving the tank. The patented design of the Pl-122 Effluent Filter cannot be duplicated.

Polylok offers the only filter on the market where you can get more GPD by simply snapping our filters together.


  • Over 122 linear feet of 1/16th inch filter slots extends time between cleanings

  • Gas deflector ball deflects solids away
  • No gluing of tees or pipe, no extra parts to buy. Comes complete with its own housing.
  • Modular design increases filtration
