The new UNI-Tee Baffle allows maintenance personnel to upgrade the effluent filter in a septic system using the UNI-Coupler from builder-grade 4-in. screens to higher capacity, higher performing filters. Accomplish this by disengaging the locking mechanism, removing the 4-in. screen and housing, and locking on any larger-sized effluent filter on the market, regardless of manufacturer. Bear Onsite.
