What is the maximum interval between required inspections of sprinkler system control valves?

The maximum interval between required inspections of sprinkler system control valves is annually. This requirement is grounded in the need for maintaining system reliability and functionality. Control valves play a critical role in managing the flow of water through a fire sprinkler system, and any malfunction or obstruction can significantly impact a system's ability to respond in the case of a fire.

Inspecting control valves annually allows for the identification of any issues such as corrosion, leaks, or mechanical failure before they can pose a serious risk. This frequency aligns with standard industry practices and regulatory guidelines, ensuring that the sprinkler system remains operational and meets safety standards.

Additionally, maintaining an annual inspection schedule ensures that the sprinkler system is kept up to date with any changes in regulations or technology, further enhancing fire safety. Regular inspections are key to ensuring that all components of the system, including the control valves, are functioning properly, ultimately contributing to the overall effectiveness of fire protection measures in place.
