Abstract: A drain cleaning system which utilizes a plumbing cable and nozzle assembly. A fluid-conveying hose is incorporated within a plumbing cable and a nozzle is affixed to the distal end of the cable and in communication with the hose. The nozzle includes a body having a rounded radius tip and a rotatably mounted ring having a plurality of radial jet passages formed therein. The ring and the body cooperatively define an annular passage therebetween. Pressurized water passes through the nozzle body and into the annular passage to produce a water bearing. The water is then discharged through the jet passages in the ring, causing the ring to rotate about the water bearing to produce a rotating spray of pressurized water. The rounded tip and ring are oriented co-axially with the tip being wider than the ring to prevent the jet passages from clogging when the nozzle is used to penetrate a clog in a pipe.
