Abstract: A storage container for a toilet plunger. Two asymmetrical opposing clamshell doors form the base and lid of the container and are hinged together at the top of the container. When not in use the plunger head is held within the container with the plunger handle sticking up through a aperture in the top of the container.

Abstract: A pneumatic-snake like appratus and method for routine clearing of clogged plumbing-drain lines in buildings and marine installations, employing an air-supply of 80-120 psi at a nozzle-generated velocity sufficient to virtually disintegrate obstructions logged within the plumbing-drain system. Owing to direct-impact infusion of high-velocity air exiting the special ball-shaped fracturing-nozzle positioned at leading-end of the snaking air-hose, the “PwrClogbuster™” is more effective at breaking-up plumbing-line clump-obstructions than conventional coiled-metal snake devices. Passed-into a drain-line to point of obstruction the pneumatic-snake operator opens a control-valve positioned between the air-hose and air-supply unit (a conventional portable air-compressor/reservoir rig);—whereupon a few thrusting blasts at point-blank are sufficient to clear an obstruction.

Abstract: A blockage clearing apparatus to clear blockages in both drain valves and in pipes. A cylindrical housing holds a piston connected to a cylindrical rod. The piston moves within the cylindrical housing in response to pressure placed on the piston either manually by an operator or by hydraulic or pneumatic power. As the piston moves in the cylindrical housing, the rod connected to the piston moves back and forth in response to the motion of the piston. The blockage clearing apparatus is mounted to a drain valve or to an opening in a pipe. When operated by pneumatic power, valves, manual or solenoid controlled, will control the flow of air in and out of ports in the cylindrical housing, creating a pressure differential within the housing to actuate the motion of the piston, hence, of the rod. The rod will extend from the housing through an open drain valve and into the pipe that is in fluid communication with the drain valve.
