Which mechanism can effectively reduce water hammer?

• A. Pressure gauge
• B. Check valve
• C. Air chamber
• D. Flow meter

Answer: (C)

The mechanism that can effectively reduce water hammer is an air chamber. An air chamber acts as a cushion within the plumbing system. When water flows through pipes, especially when valves are closed rapidly, it can create sudden changes in pressure, leading to the water hammer phenomenon, characterized by a loud banging noise and potential damage to the system. The air chamber mitigates this effect by absorbing the shock waves created by these pressure surges. It does this by allowing the air within the chamber to compress as the pressure builds, thereby reducing the intensity of the pressure wave produced when water suddenly stops or changes direction. This cushioning effect helps in minimizing noise and preventing damage to piping and fittings. While other mechanisms like pressure gauges, check valves, and flow meters play important roles in a plumbing system, they do not specifically address the issue of water hammer. Pressure gauges are used to measure system pressure, check valves prevent backflow, and flow meters measure the rate of water flow. They do not provide the same shock-absorbing capability that an air chamber does, making the air chamber the most effective choice for reducing water hammer.
