The STF-110 is a simple, reliable effluent filter that catches solids before they reach the drainfield. It installs in the outlet tee of the septic tank and pulls out for cleaning during pump-outs. No moving parts, no power, just a filter that does its job. Protecting the drainfield from solids is the single best thing you can do to extend system life.
