ABSTRACT:
A flexible filter drain is disclosed. The drain has a flexible body, a sealing washer, and a rigid brass drain stem with a sealing lip contacting the upper end of the body. The drain stem is held in sealing engagement with the flexible body by means of the cooperative action of an internal stem rib in the body and a rib member on the stem interlocking with the stem rib biased by the upper sealing lip on the stem cooperating with the upper surface of the body. A drain groove in the body provides fluid and contaminant flow through the drain when the lower party of the body and stem are displaced from axial alignment.
