The transition from the water tank to an external water supply must be made:

The transition from the water tank to an external water supply must be made smoothly to avoid disrupting the ongoing fire attack. A smooth transition is crucial because it ensures that there is no interruption in the water supply during critical moments when fire suppression is needed most. Any disruption could lead to a lapse in effective firefighting, potentially allowing the fire to grow and complicate the situation for both personnel and victims.

In the context of firefighting operations, maintaining a constant and reliable water source is essential. A seamless switch minimizes the risk of losing pressure, which can impact the ability to apply water effectively. Smooth transitions also help keep the fire operation organized and efficient, allowing firefighters to maintain their focus on extinguishing the fire rather than dealing with logistical issues related to their water supply.

While acting quickly is important, the focus must be on ensuring that the transition does not cause interruptions rather than simply speed. Similarly, using excessive force would not contribute to a smooth transition and could lead to equipment failure or other complications. Making transitions on a scheduled basis is not practical in an emergency situation where fires can escalate rapidly and require immediate attention.
