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.

[ I claim:] [1.] A portable drain cleaning apparatus comprising:a control housing adapted to be held by a user, said control housing being provided with a fluid passage having an inlet and an outlet;a release valve member arranged to control fluid flow within said passage, said release valve member being movable between at least a first position wherein said release valve member prevents fluid from flowing within said passage and a second position wherein fluid is permitted to flow therein;a coupling attached for relative rotation to the control housing during use, said coupling including an internal conduit in fluid communication with the outlet of the passage;a flexible, tubular member having first and second end portions, the first end portion of said tubular member being attached to said coupling, downstream of said release valve member, such that the tubular member can rotate relative to the control housing through the coupling, with an interior of said tubular member opening into said internal conduit;a terminal discharge member provided at the second end portion of said tubular member, said terminal discharge member being adapted to be sealingly engaged with an open end of a drain conduit and including an outlet opening in fluid communication with said internal conduit through said tubular member; andmeans for pressurizing said fluid passage upstream of said release valve member, wherein placement of said terminal discharge member at the open end of a drain conduit and shifting of said release valve member from said first position to said second position causes pressurized fluid in said passage to flow through said tubular member and into the drain conduit in order to clean the drain conduit.
