IFSTA recommends water shuttle operations use at least ______ pumpers.

• A. 1 Pumper
• B. 2 Pumpers
• C. 3 Pumpers
• D. 4 Pumpers

Answer: (B)

Water shuttle operations rely on a relay pumping setup to keep water moving from a distant source to the fire scene. Having two pumpers available creates a continuous loop: one pumper is dedicated to drafting from the water source and moving water into the relay (such as a portable tank or directly into the second pump), while the second pumper receives that water and delivers it to the attack engine and hose lay. This arrangement ensures the flow doesn’t stall while one unit refills or repositions, and it provides redundancy if one engine needs to adjust. Longer or larger operations can add more pumpers, but two pumpers form the minimum to maintain a steady, reliable supply.
