Tee baffle for use at inlet or outlet of septic and other on-site waste disposal systems
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.
1. A tee for use at the inlet or outlet of a septic tank, the tee comprising:
an elongated generally cylindrical injection molded plastic main body portion defining a tubular opening, the tubular opening being adapted to receive a filter therein;
a cylindrical injection molded plastic uppermost hub coaxial with said elongated main body portion and having an inner diameter greater than the diameter of the elongated main body portion;
an inlet/outlet port in communication with the tubular opening, the inlet/outlet port having an inlet/outlet hub at an open end thereof, said inlet/outlet hub having a diameter sized so as to receive a pipe of a first outer diameter and being adaptable to receive a pipe of a second outer diameter, said diameter of the inlet/outlet hub being greater than the diameter of the elongated main body portion;
a first injection molded plastic rib extending generally longitudinally along said elongated injection molded plastic main body portion;
a second injection molded plastic rib extending generally longitudinally along said elongated injection molded plastic main body portion, wherein said first and second injection molded plastic ribs extend outwardly from an outer wall of the elongated injection molded plastic main body portion and said uppermost hub; and
seams coextending with said first and second ribs.
2. A tee for use at the inlet or outlet of a septic tank, the tee comprising:
an elongated generally cylindrical injection molded plastic main body portion defining a tubular opening, the tubular opening being adapted to receive a filter therein;
a cylindrical injection molded plastic uppermost hub coaxial with said elongated main body portion and having an inner diameter greater than the diameter of the elongated main body portion;
an inlet/outlet port in communication with the tubular opening, the inlet/outlet port having an inlet/outlet hub at an open end thereof, said inlet/outlet hub having a diameter sized so as to receive a pipe of a first outer diameter and being adaptable to receive a pipe of a second outer diameter, said diameter of the inlet/outlet hub being greater than the diameter of the elongated main body portion; and
at least two horizontal reinforcement ribs on an outer wall of the elongated main body portion.
