When a 10% reduction in full flow pressure is observed, what must be done?

When a 10% reduction in full flow pressure is observed, identifying and correcting the cause of the reduction is essential because pressure drops can indicate potential issues within the water-based system. Pressure reductions can lead to inadequate performance of the fire protection system, impacting its ability to function effectively in an emergency.

Monitoring pressure is crucial as it ensures the system can adequately deliver water to the necessary areas when required. A significant drop, such as 10%, might result from a range of factors, including leaks, blockages, or changes in demand which could affect system performance and reliability. Therefore, finding the root cause allows for the implementation of appropriate corrective measures, ensuring the system is maintained in optimum condition.

It's important to perform these checks thoroughly to uphold safety standards and compliance with regulations. Ignoring the reduction could lead to severe consequences during an emergency, while increasing system pressure or conducting a complete overhaul may be unnecessary and costly without understanding the underlying issues first.
