ABSTRACT:
An apparatus is provided to aid in the removal of blockages from sanitary waste lines on sinks, showers and the like. Two pieces of flexible hose connect to a standard utility vacuum. The first piece of hose, approximately six to eight feet long, connects to the suction port of the vacuum. The second piece of hose, approximately 20 feet long, connects to the exhaust port of the vacuum. A special drain adapter connects to the other end of the suction hose. The adapter, with a small diameter piece of plastic pipe, and a flexible shroud which is similar in nature to a rubber plunger, forms an air tight seal between the suction hose and the drain.
