What is the recommended minimum water pressure in a distribution system during fire flow conditions?

The recommended minimum water pressure in a distribution system during fire flow conditions is 20 psi. This pressure level is essential to ensure that sufficient water flow can be provided for firefighting activities. Maintaining a minimum pressure of 20 psi helps ensure that firefighters can effectively access and utilize the water for extinguishing fires.

This standard takes into account the need for adequate flow rates and pressure for fire hydrants and other firefighting equipment. When evaluating distribution systems, it is crucial to ensure that the pressure does not drop below this threshold, as lower pressures could compromise firefighting efforts and endanger lives and property.
