What is a hard suction hose primarily used for?

1. Watering plants

2. Pumping water

3. Drafting

4. Cooling equipment

The correct answer is: Drafting

A hard suction hose is primarily designed for drafting, which involves drawing water from a static source, such as a lake, pond, or reservoir. This type of hose is specifically constructed to maintain structural integrity under negative pressure, allowing it to efficiently pull water into a pump. When firefighters need to establish water supply from a ground source rather than a pressurized system, they utilize hard suction hoses to facilitate this process. The design ensures that the hose remains rigid enough to prevent collapse when creating a vacuum during the drafting procedure.
