ABSTRACT:
A device for cleaning clogged pipes includes an elongated flexible tube, a heavy coil surrounding the flexible tube in close contact with the exterior surface thereof, and a nozzle at one end of the flexible tube. The nozzle has a plurality of perforations which are in communication with the interior of the flexible tube and which are oriented radially of the flexible tube. The device is particularly well adapted for use in a method of cleaning a clogged pipe wherein the nozzle is first forced through the material clogging the pipe, water is then discharged through the perforations in the nozzle, and the nozzle is then pulled backwards towards the material clogging the pipe while water continues to be discharged through the perforations in the nozzle.
