What pressure should be monitored to ensure safe operation of the pump?

Monitoring the intake residual pressure is crucial for ensuring the safe operation of a fire pump. This pressure indicates the amount of water that is available and how successfully the pump is drawing water from the source, such as a hydrant or an open body of water. If the intake residual pressure drops too low, it may signal that the pump is experiencing cavitation, which can lead to damage and decreased efficiency. A stable and adequate intake residual pressure is essential for maintaining pump performance and ensuring reliable water supply during firefighting operations.

Assessing water temperature, pump RPM, or hose length alone does not provide a comprehensive view of the pump's operational safety. While these factors are significant in their own right, they do not directly reflect the pump's ability to draw water or operate efficiently under the current conditions. Monitoring the intake residual pressure is a fundamental aspect of pump operation that contributes directly to firefighter safety and effective firefighting efforts.
