What device is attached to the drafting end of a hard intake hose to prevent debris from entering the pump?

The device that is attached to the drafting end of a hard intake hose to prevent debris from entering the pump is known as an intake strainer. This component is essential for maintaining the integrity of the pump and ensuring that only clean water is drawn into the system during firefighting operations. The intake strainer functions by filtering out any large particles or debris that could potentially damage the pump or reduce its efficiency.

When firefighters draw water from sources such as ponds, lakes, or rivers, it is critical to avoid introducing contaminants that could lead to mechanical failures. The intake strainer typically allows water to flow through while trapping larger objects like leaves, sticks, or sediment. This protective measure is vital for keeping the pump functioning optimally and prolonging its lifespan.

In contrast, a hose clamp is used to secure hose connections, a check valve prevents backflow in a system, and a backflow preventer protects a water supply from contamination but does not specifically serve the purpose of filtering debris from water entering the pump. Each of these other devices has different roles in firefighting and water management, but the intake strainer specifically addresses the problem of debris intake.
