ABSTRACT:
A tee baffle for use at the inlet or outlet of a septic tank or other on-site waste drainage system has a thin-walled profile and is provided with ribs along its longitudinal axis and one or more annular ribs. The tee baffle has a lowermost end for accommodating the bell end or hub of a length of pipe to facilitate lengthening the tee to the desired dimension. The tee baffle can accommodate various sizes and types of effluent filters having generally cylindrical profiles, and may be provided with inwardly-directed flanges, tabs, or ribs to hold effluent filters in place and prevent an effluent filter from becoming dislodged from the tee baffle.
