ABSTRACT:
An improved drain cleaning assembly (10) is provided having a coupling apparatus (18) designed to mate with the open end of a clogged drainpipe (12), an elongated, powered, axially-rotatable drain cable (16) passing through the apparatus (18) and into pipe (12), and water inlet and outlet lines (20, 26) coupled with apparatus (18) for delivery of water therethrough during the course of drain cleaning operations. The apparatus (18) includes a unitary main tubular body (38) receiving a drainpipe connection fitting (46) via quick-connect structure (44). The body (38) also has an internal sponge-type cable cleaning component (94) and a spray fitting (54) for directing incoming water onto cable (16). Preferably, the lines (20, 26) are each equipped with a check valve (21, 28) to control water flow through body (38) during drain unclogging and to facilitate visual verification of an unclogged condition. The inlet line (20) may also have a dispenser (24) for cleaning agent(s) such as soap, sanitizer and/or disinfectant liquids, so as to cleanse the cable (16) upon removal thereof.
