What is tandem pumping?

Tandem pumping refers specifically to the operation in which two or more fire pumps are used together to enhance water supply capabilities. In this context, the correct interpretation involves utilizing the intake capabilities of two pump units connected in such a way that allows for increased efficiency in drawing water, particularly from a hydrant. By connecting the intakes of two pumps to a single source, such as a hydrant, firefighters can maximize the available flow while reducing the burden on a single unit.

In practical scenarios, this technique can enhance the overall water supply available to the firefighting operation, especially in situations where the water demand is high. Utilizing tandem pumping can help ensure that the necessary volume and pressure of water are available for effective firefighting efforts.

The other options do not accurately reflect the definition of tandem pumping. For instance, discharging water from one pump to another typically involves a different operational strategy, as does pumping from multiple units to a single discharge point, which relates more to relay pumping rather than the specific tandem pumping technique. Relay pumping itself is characterized by transferring water from one pump to another over a distance to maintain pressure, rather than both pumps being used concurrently to draw from an intake source.
