What is the appropriate action for firefighters if water supply from a hydrant is insufficient?

Connecting multiple hydrants is the best course of action when the water supply from a singular hydrant is insufficient. This technique allows firefighters to maximize their water supply and improve flow rates by utilizing several hydrants simultaneously. By strategically linking multiple water sources, firefighters can effectively increase their available water volume for firefighting operations, which is crucial in combating larger incidents or when facing heavy fire conditions.

Utilizing only tank water limits the firefighters to the amount of water they have stored on their apparatus, which may not be adequate for sustained operations. Increasing pump pressure could potentially cause issues such as cavitation or pump damage if the supply remains insufficient. Requesting additional tankers is always an option; however, this is typically a response to a longer-term need and may take time to arrive, making it less immediate compared to the immediate action of connecting multiple hydrants.
