More Information
Water hammer, or hydraulic shock, occurs when there's a sudden change in water flow, leading to pressure surges that can damage equipment and hydrate valves.
Tips
A common mistake is not recognizing air in the system or sudden valve closures as contributing factors to water hammering.
