ABSTRACT:
A septic tank filter system comprises a mounting member adapted for attachment to an interior surface of a septic system tank, at least one open-ended, cylindrical filter housing fixed to the mounting member, and a hollow foraminated filter nested in each filter housing. The filter has a first conduit providing a fluid flow connection between the filter interior and an outlet port in the filter housing. Liquid sewage is filtered during passage from the outside of the filter to its interior. Filtrate flows through the first conduit, then through the filter housing outlet port, thence through the mounting member and finally exits the tank through the outlet pipe in the tank wall. A score line in the filter housing side wall permits ready removal of a section thereof to form an inlet port. Telescoping channel members on the outside of the filter housings allow them to be interconnected with the outlet port of one in fluid flow connection with the inlet port of another. A second conduit in the filters provides fluid flow communication between the filter housing inlet port and the filter interior.
