A plunger for clearing a drain, the plunger comprising:
- a plunger body comprising a handle and a gripping section;
- a reservoir located within the plunger body and terminating at an opening in the lower body portion, where the opening is adapted to direct fluid into the drain;
- a piston slidably moveable in the reservoir, such that movement of the piston displaces fluid from a first reservoir portion to a second reservoir portion, where the second reservoir portion comprises at least one port in the lower body portion allowing liquid in the second reservoir portion to exit the plunger body at a location away from the upper body portion;
- and
- a compliant member located adjacent to the opening, where the compliant member is sufficiently compliant to form a seal between the lower body portion and the drain allowing fluid to be drawn into the first reservoir portion via the opening.
2 more elements
