In drafting operations, what is the role of the strainer?

In drafting operations, the primary role of the strainer is to prevent debris from entering the pump. When water is drawn from a static source, such as a pond or a cistern, the strainer is placed at the intake of the suction hose. It serves as a barrier to ensure that larger particles, like leaves, sediment, or other debris, do not get pulled into the pump. This is crucial for maintaining the integrity and efficiency of the pump, as debris can cause clogs, reduce performance, or even damage the pump components over time.

In this context, it's essential to understand that while other choices may seem relevant, they do not accurately describe the specific purpose of the strainer in the drafting process. The primary goal is protection against contamination of the water supply entering the pump system.
