What can valve exercising help to prevent in water distribution systems?

Valve exercising is a critical maintenance practice in water distribution systems that involves the regular operation of valves to ensure they can open and close properly when needed. This practice is particularly significant in preventing corrosion and loss of functionality.

Over time, valves may become stuck or corroded due to lack of use, buildup of sediment, or chemical reactions with water constituents. By exercising the valves, you allow for movement that can help clean the valve surfaces, dislodge any accumulated debris, and prevent corrosion from progressing. Regular operation ensures that the mechanisms of the valves remain functional and accessible, thus avoiding emergency situations where a valve cannot be operated when needed, such as during maintenance or in case of a system failure.

While other issues like increased water pressure, water contamination, and leaks can be relevant in a water system's operation, they are not the primary concerns directly addressed by valve exercising. This maintenance activity directly targets the integrity and functionality of valves, thereby enhancing the overall reliability of the water distribution system.
