Hard suction hose is used on which equipment?

• A. Used only on drafting from ponds
• B. Used on Water Tender 22 and for pump testing
• C. Used for ladder operations
• D. Used for air lines

Answer: (B)

Hard suction hose is designed to connect to a pump intake to draw water from a static source, so it’s a key tool on pumping apparatus. It’s used on equipment like Water Tender 22 to pull water into the pump and also during pump testing to simulate drafting conditions and verify the pump’s suction capability. It isn’t used for ladder operations, which involve ladders, nor for air lines, which carry breathable air or provide pneumatic supply. So the option mentioning Water Tender 22 and pump testing best describes its typical uses.
