Abstract
A system and a tool for clearing an obstructed pipe or drain is presented. The system comprises the tool and a housing. The tool comprises a plunger and a protective sleeve with a closed end. The plunger comprises a dowel shaped flexible portion and a dowel shaped rigid handle portion, the distal end of the rigid handle portion being fixedly attached to the proximate end of the flexible portion by a connection device. The protective sleeve is comprised of a water soluble material that is configured to conform to the shape of the dowel shaped flexible portion and at least a portion of the dowel shaped rigid handle portion when the flexible portion is inserted therein, the water soluble material being chemically formulated and mechanically formed to maintain watertight integrity when submerged in water. The housing is configured to store the plunger and the protective sleeve when not in use.
