What purpose does a flow test serve in a sprinkler system?

A flow test is a critical procedure in evaluating the performance and reliability of a fire sprinkler system. Its primary purpose is to measure the water supply available to the system, ensuring that there is sufficient water flow and pressure for effective operation during a fire event. This measurement helps determine whether the existing water supply can support the required flow rates necessary for the sprinklers to work effectively.

Understanding the water supply is essential because if there is not enough water available, the effectiveness of the sprinkler system in extinguishing or controlling a fire is significantly compromised. The flow test identifies key parameters such as the available flow rate in gallons per minute (GPM) and the pressure in pounds per square inch (PSI), which are both crucial for system design and functionality.

This information also aids in confirming that the system is compliant with local codes and standards, which often dictate minimum water supply requirements. Thus, determining the water supply through a flow test plays a vital role in the overall safety and effectiveness of the sprinkler system.
