What should be done if the water supply for a sprinkler system becomes unreliable during testing?

When testing a sprinkler system, it is crucial to have a reliable water supply to ensure accurate results and system integrity. If the water supply becomes unreliable during testing, immediately suspending the test is the best course of action. This decision prioritizes safety, system functionality, and the accuracy of the testing results.

Continuing the test without a dependable water supply may lead to inaccurate data, potentially resulting in a failure to identify issues that could affect system performance when activated in an emergency. Additionally, proceeding with unreliable conditions could undermine the system's safety assessments, complicating future evaluations and potentially putting lives at risk in a real fire event.

By suspending testing until the water supply is restored, the integrity of the testing process is maintained, ensuring that the results are valid and reliable. This approach protects not only the personnel conducting the test but also the occupants of the building that relies on the sprinkler system for safety.
