Why is it necessary to build up pressure slowly when supplying automatic sprinkler systems?

Building up pressure slowly when supplying automatic sprinkler systems is crucial to prevent system damage. Automatic sprinkler systems are designed to handle specific pressures and flows, and introducing water too quickly can cause sudden pressure surges. These surges can lead to structural damage within the pipes, fittings, and even the sprinkler heads themselves. Over-pressurization can cause leaks or bursts, rendering the system ineffective during a fire emergency and potentially causing costly repairs.

Gradual pressure buildup allows air to escape from the system, which helps to stabilize the pressure throughout the system. This careful management of pressure ensures that all components operate smoothly and reduces the risk of mechanical failures that could compromise the system’s effectiveness.
