PURPOSE: A nozzle for cleaning a water supply pipe and a drain pipe is provided to efficiently remove the large amount of sludge stacked on the bottom surface of the water supply pipe and the drain pipe such as especially a curved part. CONSTITUTION: A nozzle for cleaning a water supply pipe and a drain pipe comprises a cone-shaped head (10), a nozzle (20), and a body (30). The nozzle is installed in the lower part of the head in order to be symmetrical to the head and injects pressure water through an injection hole (23) while receiving the pressure water through a connection hole formed on the center. The body is fixed to between the nozzle and the head and includes a weight inside so that the injection hole of the nozzle always faces the bottom surface. |
