During a sprinkler system test, what should be assessed if a pressure drop is detected?

When a pressure drop is detected during a sprinkler system test, identifying the cause of the pressure drop is crucial. This step is essential because a pressure drop may indicate potential issues such as leaks, blockages, or valve malfunctions within the system. By pinpointing the root cause, corrective actions can be taken to ensure that the system functions properly and meets safety standards.

Addressing pressure issues directly supports system reliability and effectiveness in fire suppression. If the cause is not identified and resolved, the integrity of the sprinkler system could be compromised, leading to inadequate performance in an emergency situation.

Visualizing the entire installation or assessing environmental conditions may provide some context or additional insights, but these actions won't directly address or resolve the immediate concern raised by the pressure drop. Waiting for the next scheduled testing would not be a proactive approach and could lead to further complications or increased risk in case of a fire.
