How often must an inspector test the operation of control valves on a sprinkler system?

The operation of control valves on a sprinkler system must be tested annually to ensure they are functioning correctly. This requirement is crucial because control valves play a vital role in the overall operation of the fire protection system, allowing for the initiation and cessation of water flow during an emergency or maintenance scenario. Regular testing ensures that the valves can be opened and closed without obstruction, which is critical for effective fire suppression.

Annual testing also aligns with industry standards and best practices, helping to maintain compliance with fire safety codes. Given the importance of these valves in operating under emergency conditions, annual checks help identify any potential issues before they become serious problems, ensuring that the sprinkler system will perform as needed when a fire occurs. This level of diligence supports overall safety and reliability in fire protection measures.
