Wall Hydrants
A square flange on wall hydrants allows them to be flat placed against a building's exterior wall or installed into a round or square box to recess the hydrants into the wall. They give access to water in a building's outdoor areas. The flow of water through the hydrant's valve is not controlled by handles on wall hydrants. Instead, they come with a key that opens or closes the valve to start or stop the flow of water, preventing unlawful hydrant use.
