Abstract
A temporary sealing device for sealing a waste discharge conduit from an RV to an inlet receptacle of a waste receiving reservoir. The sealing device includes an inflatable bladder which is mounted so as to be positionable between the discharge conduit and the receptacle. A pump inflates the bladder to a size which seals the opening between the receptacle and the conduit to inhibit removal of the conduit and prevent the discharge of waste therearound. The sealing device is also provided with a valve which allows the bladder to be deflated after the transfer of waste and permits the conduit to be withdrawn from the receptacle.
