In drafting operations, what is defined as the elevation difference between the static water source and the center of the pump?

In drafting operations, the elevation difference between the static water source and the center of the pump is referred to as lift. Lift is crucial because it directly impacts the ability of the pump to draw water from the source. More specifically, it represents the vertical distance that the pump must move water in order to achieve flow.

Understanding lift is essential for efficient drafting operations as it helps firefighters evaluate whether the pump can successfully operate from a given water source based on its height relative to the pump. If the lift is too high, it may exceed the pump's capacity, leading to difficulties in water supply during fire operations. This knowledge is vital for effective firefighting strategies and resource management on scene.
