If a sprinkler system has been altered or repaired, what must be done before it is put back into service?

When a sprinkler system undergoes alterations or repairs, it is essential to perform a full inspection and testing before returning the system to service. This comprehensive process ensures that all components of the sprinkler system are functioning correctly and meet current safety standards. Alterations or repairs can potentially affect the system's performance, so conducting a thorough inspection helps to identify any issues that could lead to malfunction or diminished effectiveness in the event of a fire.

The full inspection may include checking for proper pressure levels, verifying the operation of all valves, ensuring that sprinkler heads are unobstructed and properly aligned, and confirming that the alarm systems are functioning. Testing might include flow tests to ensure that water supply levels are adequate and that the system activates correctly.

While a visual assessment or notifying local authorities are important steps in maintaining regulatory compliance and safety measures, these actions do not replace the need for in-depth testing and inspection following repairs or alterations. Similarly, simply replacing old components without performing a full evaluation does not guarantee that the system will perform as required in an emergency scenario. Therefore, thorough inspection and testing are critical to ensuring the reliability and safety of the fire protection system.
