What is the purpose of a water hammer arrestor?

• A. To increase water pressure in the system
• B. To absorb shock in plumbing systems and prevent noise
• C. To filter impurities from the water
• D. To regulate water temperature

Answer: (B)

A water hammer arrestor serves a critical role in plumbing systems by absorbing the shock that occurs when a fast-moving fluid suddenly stops or changes direction. This phenomenon, known as a water hammer, can create significant pressure spikes in the piping system, leading to noisy and potentially damaging vibrations. When plumbing fixtures are turned off abruptly, the water that has momentum collides with the closed valve or fixture, resulting in a sharp increase in pressure. The water hammer arrestor features an air chamber or a spring that compresses to absorb this shock, thereby dampening any noise and reducing stress on the pipes and fixtures. This not only helps to maintain the integrity of the plumbing system but also creates a quieter environment in the building. The function of the water hammer arrestor is distinct from other devices; it does not play a role in increasing water pressure, filtering impurities, or regulating temperature, which are purposes associated with other types of plumbing components.
