Which type of hose is primarily used for drafting operations?

The primary type of hose used for drafting operations is a hard intake hose. This type of hose is rigid and designed to maintain its shape when submerged in a static water source, such as a lake or a pond. Drafting operations require a hose that can create a strong vacuum, allowing the pump to draw water effectively from below the water surface. Hard intake hoses are built to withstand the external pressure of the water while maintaining a secure connection to the pump.

Soft intake hoses, while used for various applications, may not offer the structural integrity necessary for drafting, especially when working with substantial water sources. Supply hoses and discharge hoses serve different purposes related to transporting water to and from the fire scene but are not specifically designed for drafting water.

Thus, for the specific need of drawing water effectively from a source, the hard intake hose is the preferred choice, as it provides the durability and performance required in drafting scenarios.
