Polylok PL-122 Effluent Filter

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).




    Offers 122 linear feet of 1/16” filter slots, which significantly extends time between cleaning
    Has a flow control ball that shuts off the flow of effluent when the filter is removed for cleaning
    Has its own gas deflector ball which deflects solids away
    Installs easily in new tanks, or retrofits in existing systems
    Comes complete with its own housing. No gluing of tees or pipe, no extra parts to buy
    Has a modular design, allowing for increased filtration
    Alarm accessibility
    Accepts PVC extension handle
    Comes with pipe adapter

(GPD). Easily installs in any new or existing 4" outlet tee.

Wonderful product for the price. I hope it last because the last filter (Zabel) only last 20 years!

I thought it would be beefier for use at the tank outlet. Being NSF certified does not mean that I guess. The filter does not reinsert very easily. I would have exchanged it but it would likely result in the same product performance. I may get the dremel out.
