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.
