ABSTRACT:
A method and an apparatus are disclosed for cleaning water pipe. The pipe is preferably connected to a source of water which normally flows through the pipe to an outlet. A valve is positioned at the outlet and is rapidly opened and closed. When the valve is closed a pressure pulse is created in the pipe and travels towards the source of fluid. This wave is reflected back from the source towards the outlet. The alternate waves expand and contract the pipe wall, and cause pressure fluctuations within the pipe. The combined action removes scale from the wall of the pipe, and when the valve is opened the removed scale passes out of the pipe.
