What should be done if you notice a significant drop in pressure while pumping?

Noticing a significant drop in pressure while pumping is a critical situation that requires immediate attention. One of the first actions to take is to check for leaks. A drop in pressure can indicate that there is a breach somewhere in the system, such as a broken hose, a malfunctioning connection, or a failure in the pump itself. Identifying and addressing leaks is essential because it helps to maintain operational integrity and safety during firefighting efforts.

Other actions, like increasing the throttle or adjusting the gear shift, may not resolve the issue and could exacerbate the problem. Additionally, shutting the pump down immediately could create further complications, especially in an emergency situation where maintaining water supply is paramount. Therefore, checking for leaks is a proactive measure to diagnose the issue before taking further steps.
