Dual Pumping configuration involves which arrangement?

• A. Long pumping distances, one pumper feeds another
• B. Two pumpers discharge into a shared line
• C. One hydrant feeds two pumpers, connect intake to intake
• D. One pumper discharges into the intake of another to build pressure

Answer: (C)

Dual pumping means two pumpers drawing from the same water source in parallel. In this setup, a single hydrant or other source feeds both pumpers, and the intake lines are connected together so both pumpers can draft water simultaneously. This arrangement increases total available flow and helps maintain pressure along longer hose lays, which is useful when a single pumper can’t meet the demand. The other described configurations involve pumping water in series or mixing discharges, which are different techniques and achieve different effects, whereas dual pumping specifically relies on sharing the intake from one source to supply two pumpers.
