Claims20
A plumbing plunger system comprising:
- a plunger cylinder body;
- a plurality of sealing members each arranged to be separately mounted on a bottom end of the cylinder body with the others of the sealing members removed;
- each sealing member being shaped and arranged to engage or penetrate a drain hole of a plumbing device including a toilet, sink, shower drain, tub drain and floor drain;
- a double acting piston mounted in the cylinder and connected to a shaft having a handle at an upper end of the cylinder for manual movement of the piston within the cylinder:
- the sealing members each having an opening therethrough such that operation of the piston by the handle moves water between the drain hole and the cylinder for pumping water into the drain hole or extracting water from the drain hole.

- a first one of the sealing members comprising a cylinder portion with a bottom wall defining by an in-turned lip so as to form a sealing ring for surrounding the drain hole;
- a second one of the sealing members comprising an upper sealing ring and a generally conical wall extending downwardly from a sealing ring coaxial to the cylindrical body.
- a third one of the sealing members comprising a cylindrical portion with a transverse bottom wall and a tube extending downwardly from the bottom wall of the sealing member which tube is offset to one side from a central axis of the cylinder.
