Abstract:
1. A blockage clearance device for a toilet conduit comprising: a pair of elongated tubes, each of said tubes having opposite ends disposed between an internal passageway; an expandable element secured on a selected end of said tubes and said element having an internal cavity with a selected one of said tubes connected therewith; a source of pressurized fluid in communication with said tubes for introducing pressurized fluid to said internal cavity of said expandable element or to a toilet drainage conduit; said expandable element adapted to radially expand to close and seal with said toilet drainage conduit in response to introduction of said pressurized fluid; a single valve operably carried on said tubes for alternately conducting said pressurized fluid to either said internal cavity or to said toilet drainage conduit; said single valve having a housing with an input port and with a first output port communicating with said passageway of said tube connected to said internal cavity and a second port communicating with said passageway of said tube connected with said toilet drainage conduit; a manually operated plunger in said housing having a first chamber and a second chamber and movable within said housing to conduct pressurized fluid from said source of pressurized fluid to either said first output port or to said second output port; said source of pressurized fluid detachably coupled to said input port of said housing for alternatively supplying said pressurized fluid to flow through either said first or said second output port to forcibly expand said expandable element or to clear said toilet drainage conduit; said expandable element includes an outer exterior surface carrying a plurality of spaced-apart ribs deformable upon compression to provide a sealing relationship with said toilet drainage conduit; and said selected end of said tube having an outwardly projecting linear end portion supporting and mounting said expandable element.
