Abstract
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.

Claim 1
Independent Claim
154 words
A method of cleaning a clogged pipe employing a device comprising: (a) an elongated flexible tube; (b) a heavy coil surrounding said flexible tube in close contact with the exterior surface thereof; (c) a nozzle at one end of said flexible tube, said nozzle having a plurality of perforations which are in communication with the interior of said flexible tube and which are oriented radially of said flexible tube; and (d) first means for connecting said flexible tube to a source of water, said first means being located at the other end of said flexible tube, said method comprising the steps of: (1) forcing said nozzle through the material clogging the pipe; (2) discharging water through the perforations in said nozzle after it has passed through the material clogging the pipe; and (3) pulling the nozzle backwards toward the material clogging the pipe while continuing to discharge water through the perforations in the nozzle.
