ABSTRACT:
A unitary plumbing apparatus is disclosed that serves as a drain waste water strainer trap for sinks and other plumbing fixtures as well as a filter or strainer for the exiting waste water to keep the drain pipe free flowing or to recover valuables lost into drain lines. The filter or strainer can be removed from the apparatus for cleaning by removing a cap at the bottom of the apparatus. The cap can be removed by hand. The top and bottom sections of the body of one embodiment of the apparatus are mutually rotatable for convenience in connecting inlet and outlet apparatus conduits to standing plumbing drain piping.
