Abstract: A plunger device for unblocking a clogged drain or pipe, comprises a valve housing interposed between a handle and a suction cup; a valve seat having an opening for communicating the cup with the housing; a fluid outlet formed in the housing to provide a fluid path to the outside of the device; a valve ball positioned in the housing to close said opening of the valve seat and said fluid outlet when said ball is positioned on the seat, a bolt moveable in said housing to abut said ball for locking the ball between the bolt and said seat, thereby causing fluid under pressure to flow in one direction-into the clogged drain, the bolt being movable away from said ball to unlock the ball and open said fluid outlet, said ball moving freely inside the valve housing when said ball is unlocked, thereby enabling fluid to flow in the opposite direction only—out from the clogged drain; and switch means associated with the bolt and lock and unlock the valve ball when clearing the clogged drain.
