For effective water delivery, firefighters must monitor pressure settings, as this directly affects the performance of the nozzle and the water's reach and force. Proper nozzle pressure is critical to ensuring that water is discharged at the optimal rate and with the appropriate force to extinguish fires effectively. The specific pressure settings depend on various factors such as the type of nozzle being used, the distance to the fire, and the conditions of the environment.

Monitoring pressure settings allows firefighters to achieve the desired flow rate and ensure they can adapt to changing conditions on the fireground. If the nozzle pressure is too low, it may not produce sufficient reach or spray pattern to combat the fire, while too high a pressure can lead to less control and can potentially create safety hazards. Thus, maintaining appropriate pressure settings is essential for effective firefighting operations.
