What maintenance action can help prevent water hammer in a system?

Regular valve inspections and replacements play a crucial role in preventing water hammer in a distribution system. Water hammer occurs when there is a sudden change in water flow, often due to rapid valve closures or malfunctions, leading to pressure surges that can damage pipes and fittings. By routinely inspecting valves, you can identify and address issues such as wear, leaks, or improper operation before they lead to more serious problems. If any valves are found to be faulty or not functioning as intended, replacing them promptly can maintain a steady and controlled flow of water throughout the system, minimizing the risk of sudden pressure changes that cause water hammer.

In contrast, while increasing water supply pressure could potentially worsen the effects of water hammer, adding storage tanks may not directly address the root cause of pressure surges. Decreasing the temperature of water may impact system dynamics but does not fundamentally address the issues related to valve operation that lead to water hammer. Thus, regular maintenance of valves is a proactive approach to ensuring a stable operation and avoiding the costly consequences of water hammer.
