Abstract: A nozzle is provided for cleaning the interior of pipes that is capable of cutting through obstructions disposed in the interior of pipes. The nozzle comprises a three-dimensional (3-D) fluid mechanics comprising a 3-D redirection configuration that redirects high-pressure fluid received in the nozzle from a fluid source onto multiple pathways, or channels, toward rearwardly-facing jet outlets. The 3-D fluid redirection configuration redirects the water in a manner that reduces or eliminates vibrations in the nozzle that can degrade performance and cause other problems.

Abstract: A cutter is provided for cutting through obstructions disposed in the interior of pipes ranging in size from approximately 8? to approximately 15? in diameter or from approximately 12? to approximately 24? in diameter. The cutter has been reduced in size relative to known root cutters to be capable of being used with smaller-diameter pipes, but is sufficiently powerful to cut through obstructions, such as mineral deposits, for example, that known flexible cutters capable of being used with these smaller-diameter pipes are incapable of cutting through.
