During in-line pumping, what pressure should the supply be augmented to?

In the context of fireground operations and in-line pumping, the correct pressure for the supply line should be augmented to 15 psi minimum. This pressure is necessary to ensure adequate flow and pressure are delivered through the system to support firefighting efforts. Augmenting to this level helps to maintain the required pressure for effective water delivery to the pump, preventing surges or insufficient flow that could compromise firefighting operations.

In-line pumping typically involves connecting multiple hoses or pumps, and the 15 psi minimum is a standard that supports operational efficiency while also ensuring safety for the personnel involved in the operation. Using a higher pressure might unnecessarily increase strain on the equipment and could lead to complications or failures in the system.
