What is a water hammer?

A water hammer refers to a pressure surge that occurs when a fluid in motion is forced to stop or change direction suddenly. This phenomenon is typically the result of a quick closure of a valve or a rapid change in water flow, which creates a shock wave in the plumbing system. The sudden change results in elevated pressure levels, producing a sound similar to a hammer striking a pipe.

Understanding this concept is crucial for managing plumbing systems effectively, as water hammer can lead to various issues, including noisy pipes, wear and tear on the plumbing, and even potential damage if left unaddressed. Thus, recognizing water hammer is essential in maintaining the integrity and functionality of water systems.
