ABSTRACT:
A pool plug (10) is disclosed comprising a plunger member (12) and a base member (14). The base member (14) is cylindrical having an axial passageway (30) therethrough and opposed annular skirt flanges (32,36) projecting toward each other from opposite rims (26,28) of the member (14). The flange (32) collapses diametrically to allow the base member (14) to be inserted into a panel aperture, and skirt flange (36) depresses to a point that the lower flange (32) is free to open up and resume its original form, capturing the panel between the flanges (32,36). Composed of elastomeric plastic, the flanges (32,36) flex to allow use of the plug in pool panels having a thickness variable within a specified range. The plunger member (12) reciprocally moves upward and downward within the passageway (20) and includes ports (54) that open and close in response thereto. An inwardly directed annular sealing flange (40) engages the plunger member (12) to seal the plunger when it is pushed downward into a closed position.
