A curb vent stack plunger for clearing sewer drains includes an elongated pole. A first substantially circularly shaped rubberized disc is located adjacent the bottom end of the pole and lies in a first plane perpendicular to the axis of the pole. A second substantially circularly shaped rubberized disc is secured to the pole at a distance spaced upwardly from the bottom end. The second disc lies in a second plane perpendicular to the pole axis but parallel to the first disc. A soft rubberlike semi-spherically shaped bumper is secured to the remote bottom end of the pole. |
