Which hose is primarily used in drafting operations?

• A. Soft intake hose
• B. Hard intake hose
• C. Suction hose
• D. Discharge hose

Answer: (B)

Drafting involves pulling water into the pump from a static source, so the hose used must withstand suction without collapsing. A hard intake hose is rigid and non-collapsible, with reinforced walls that resist the vacuum created by the pump, ensuring a steady, uninterrupted flow during drafting. Soft intake hoses are flexible and can kink or collapse under suction, interrupting water supply. A suction hose is a general term for hoses used to suck water, but the hard intake hose is the standard specifically designed for draft operations. A discharge hose handles moving water away from the pump after it’s drawn, not for pulling water in.
