When drafting from a static water source, what is the ideal condition to select the source?

When drafting from a static water source, the ideal condition is to select a source that requires the minimum amount of lift. The lift refers to the vertical distance the water must be raised from the source to the pump. The less lift required, the more efficient the drafting operation will be. Reducing the lift minimizes the strain on the fire apparatus, improves the flow rate, and can lead to more effective firefighting efforts.

Choosing a source with minimal lift allows the pump to operate more effectively, as it can achieve the necessary pressure to deliver water to the system without excessive energy expenditure. This is particularly important during emergency situations, where quick and reliable water delivery is critical.

Selecting a source that requires maximum lift, elevated water sources, or sources with significant debris would introduce challenges that could hinder the efficiency and effectiveness of the drafting process. These options can lead to increased workload on the pump, possible cavitation, reduced water flow, or obstructions that complicate water intake.
