Retired Galesburg firefighters help repaint fire hydrants ... Primarily, we need to know how much water is available from the closest hydrant so that we may select the appropriate size hose lines for the size and complexity of the fire, but not select lines which would exceed the capacity of the hydrant and thus be ineffective. After flowing 500 gpm, the residual pressure is down to 40 psi. When the required fireflow is over 2,500 gpm, the fire code official may require the fire hydrants be served by a main which loops and reconnects back into a distribution supply main, and said hydrants shall be located as designated by the fire code official. If you can turn on a fire hydrant, you already know how to use the Fire Flow Pro.
