What is the technique called when two pumpers connect in series to obtain water from a hydrant?

Tandem Pumping is the technique where two pumpers are connected in series to draw water from a hydrant. This method allows for increased pressure and flow rate, which can be critical in firefighting operations, especially when dealing with large-scale incidents or when water supply from a single source is insufficient.

In tandem pumping, the first pumper typically takes water from the hydrant and pushes it into the second pumper. This arrangement enables the second pumper to increase the pressure, making it easier to deliver water over longer distances or to higher elevations. This technique can be particularly advantageous in situations where the fire may be far from the water source or where there is a need to boost pressure significantly.

Understanding the importance of tandem pumping helps firefighters effectively utilize their resources and improve water delivery systems in emergency situations.
