How often should sprinkler system valves be exercised?

Sprinkler system valves should be exercised at least twice a year to ensure they operate effectively when needed. Regular exercising of these valves helps to prevent the buildup of corrosion and debris, which can impede their function. By exercising the valves, technicians can confirm that they open and close properly and also identify any maintenance needs before an emergency arises.

This practice is crucial for maintaining the reliability of the fire protection system, as a valve that is not exercised might become stuck or inoperable when it's required, potentially compromising the effectiveness of the sprinkler system during a fire. The recommended frequency of twice a year strikes a balance between ensuring system readiness and managing maintenance resources effectively, reinforcing the importance of periodic checks in fire safety protocols.
