ABSTRACT:
An improved apparatus for temporarily sealing a vent or overflow aperture provided in the upper portion of a fixture such as a wash basin, sink, bathtub or bidet so that a pneumatic or hydraulic type sewer cleanout device can be used to clear a blockage located in a sewer line downstream of the fixture by generating fluid pressure within the sewer line intermediate the blockage and the main water drain of the fixture. The apparatus is of simple construction and embodies an assembly made up of a pressure plate, a threaded tube and a wing nut which can be threadably advanced along the tube to cause the pressure plate to sealably engage the apertured wall of the fixture.
