What is the procedure when a new line becomes the highest-pressure line?

When a new line becomes the highest-pressure line, the proper procedure is to fully open the gate of that new highest-pressure line. This ensures that the line can deliver the maximum amount of water and pressure necessary for effective firefighting operations. Fully opening the gate allows for optimal flow rates and ensures that the system can utilize the newly designated high-pressure source for firefighting or other emergency responses.

This action is critical in situations where immediate access to high pressure is required, such as when battling significant fire incidents or when trying to suppress a rapidly spreading fire. By fully opening the gate, firefighters ensure they are maximizing their resources and providing adequate support to their efforts on the scene.

Additionally, having the new highest-pressure line fully opened helps maintain balance within the water distribution system, avoiding potential scenarios where pressure discrepancies might lead to complications or inefficiencies in the firefighting operation.
