Why is it essential to perform flow tests before installing a sprinkler system?

Performing flow tests before installing a sprinkler system is crucial because it ensures that the water supply can adequately meet the required flow and pressure needed for effective system performance. Sprinkler systems are designed based on specific flow and pressure requirements to ensure they can provide sufficient coverage and suppression capabilities in the event of a fire.

If the flow test reveals that the water supply does not meet these requirements, the system may not function properly, potentially compromising fire safety. Understanding the available water supply allows for adjustments in system design or selection of alternative water sources, such as additional tanks or pumps, to ensure that the system can effectively extinguish a fire.

Other considerations, like aesthetic design, valve location, or building height, while important in specifics of installation and planning, do not directly impact the fundamental operational capabilities of the sprinkler system in the way that flow and pressure do. Hence, focusing on ensuring adequate water supply is integral to a successful and functional sprinkler installation.
