Water hammer (or, more generally, fluid hammer) is a pressure surge or wave caused when a fluid (usually a liquid but sometimes also a gas) in motion is forced to stop or change direction suddenly (momentum change). A water hammer commonly occurs when a valve closes suddenly at an end of a pipeline system, and a pressure wave propagates in the pip...

• A metal hammer used when heated, as by dipping in hot water, to blister the skin, as for counterritation. • A concussion, or blow, made by water in striking, as against the sides of a pipe or vessel containing it. • A vessel partly filled with water, exhausted of air, and hermetically sealed. When reversed or shaken, the w...

A destructive, high-pressure surge in a water supply piping system accompanying the quick closure of valves or faucets on the system. The surge causes a shock wave which vibrates the pipes causing them to bang, knock or 'hammer' against the wall or floor.

A loud annoying noise or vibration made by your pipes when you turn the water on or off. It is caused by a pressure surge or wave when water in motion is forced to stop or change direction suddenly; for example, when a valve is suddenly closed. This pressure wave can cause major problems, from noise and vibration to pipe collapse. Water hammer can ...
