ABSTRACT:
A readily transportable, compact and self-contained drain cleaning apparatus includes a hand-held control housing that is provided with an internal passage into which a release member and an adjustable regulating unit extend at spaced intervals such that a fluid chamber is defined between the release member and the regulating unit within the internal 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 downstream of the regulating unit. Upstream of the release member, the control housing has an elongated tube attached thereto and the tube has an end, remote from the control housing, provided with a terminal discharge member that is adapted to be sealingly engaged with an open portion of a clogged drain conduit. With this construction, shifting of the release member causes a supply of pressurized fluid, delivered into the fluid chamber from the pressurized cartridge through the regulating unit, to flow through the tube and terminal discharge member and into the drain conduit as a momentary burst of pressurized fluid while the regulating unit retards a flow of additional pressurized fluid from the cartridge to the fluid chamber.
