How often should a full flow test be performed on a sprinkler system?

A full flow test on a sprinkler system is important for verifying that the system can deliver the necessary water flow and pressure required for effective operation during a fire emergency. Performing this test every 5 years is in accordance with industry standards and codes, which often stipulate that routine testing must be conducted to ensure systems are functioning properly and to identify any issues that may affect performance.

This timeframe helps ensure that any changes or degradation in the system's components, such as pipes, valves, and sprinkler heads, are monitored and addressed in a timely manner. Testing too frequently could lead to unnecessary disruptions and costs, while testing too infrequently may result in potential failures during actual emergencies, compromising safety. Therefore, conducting a full flow test every 5 years strikes a balance between maintaining safety standards and practical consistency in monitoring the system’s performance.
