An intake relief valve comprises a bronze sectional gate positioned within the valve chamber adjacent to an outlet section of the valve. A quick attachment coupler of the valve connects the outlet section typically to a pumper fire truck, and a hose from a hydrant or draft source connects to an opposite inlet section of the valve. When the valve is closed and the hose is disconnected from the valve with the valve connected to the pumper fire truck, there is no water remaining in the valve chamber. Any residual water is released by a pit drainage outlet on the bottom wall of the valve. Not having water stored in the valve eliminates corrosion problems within the valve, when the valve is connected to the pumper fire truck.
