Why is valve exercising important in water distribution?

Valve exercising is the process of regularly opening and closing water distribution valves to ensure they remain functional and operable. This practice is crucial for several reasons. Over time, valves can become stuck due to sediment buildup, corrosion, or lack of use, which can compromise their ability to control flow within the water distribution system. Regular exercising helps to identify any issues before they develop into major problems, thereby ensuring that valves will operate correctly in an emergency situation, such as when a main break occurs or during maintenance activities.

By exercising the valves, operators can also confirm that they are properly seated and that seals are functioning, which helps in maintaining the overall reliability of the water distribution system. This proactive maintenance reduces the risk of unanticipated failures, which can lead to significant water service disruptions.

While enhancing water pressure, preventing rust accumulation, and reducing water loss are important aspects of water distribution management, the primary reason for valve exercising centers on ensuring that each valve will perform as required when needed.
