WebNov 19, 2010 · To have adequate pressure to overcome hose losses you'd want more like 20 psi minimum at the outlet from the hydrant. However this is all theoretical, it has nothing to do with what the system can actually deliver. It's possible the hydrant can flow anywhere from 50 to 5000 gpm at 20 psi residual, depending on the system capability.
