Abstract
A readily transportable, compact and self-contained drain cleaning apparatus includes a hand-held control housing provided with an internal passage into which a release valve member extends for regulating fluid flow through the passage. The control housing includes a cartridge housing portion for attaching a miniature cartridge, containing a pressurized gaseous medium and preferably either a drain cleaning or algaecide fluid, thereto with an interior of the cartridge opening into the internal passage. The cartridge housing is provided with a safety aperture for pressure relief purposes. The control housing has an elongated tubular member attached thereto through a rotatable coupling and the tubular member has an end, remote from the control housing, provided with a terminal discharge member that is adapted to be sealing engaged with an open portion of a clogged drain conduit. With this construction, shifting of the release member causes a supply of pressurized fluid from the pressurized cartridge to flow through the tubular member and terminal discharge member and into the drain conduit in order to clean the drain conduit.

6550074 - Air-burst drain plunger - Owned by M. A. G. Engineering & Mfg. Co. (Huntington Beach, CA)

An affordable plumbing device that uses a compressed gas and a burst disk having a relatively even surface of substantially uniform thickness to produce a sudden discharge of energy to forcibly act against any obstruction that may interfere with the proper function of a drain. The plumbing device has a cylindrical chamber for receiving the compressed gas and may generally take the shape of a plunger, which is flexible to use and is easy to store. A portion of the chamber forms a receiving chamber with the burst disk for harnessing and directing the energy of the compressed gas to clear the drain.

7000284 - Drain vacuum attachment kit

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.
