When should a valve be inspected for tampering or unauthorized operation?

Valves in fire protection systems, such as those used in sprinkler systems, play a crucial role in controlling the flow of water and ensuring that the system operates effectively in an emergency. Regular inspections are vital to maintain the integrity and functionality of the system.

The recommendation to inspect valves annually aligns with industry standards and best practices. This frequency allows for adequate monitoring of the system's condition, identifying any signs of tampering or unauthorized operation that could compromise safety. Performing this inspection annually ensures that any unauthorized adjustments or damages can be addressed promptly, thus maintaining the reliability of the fire suppression system.

Inspections occurring at shorter intervals, such as every three months, while seemingly thorough, may not be necessary and could be impractical for many facilities. Longer intervals, like every two years, would potentially lead to undetected issues that could put lives and property at risk. Therefore, an annual inspection strikes an effective balance, allowing for routine checks that help ensure the proper functioning of the valve without being excessive.
