Abstract
An embodiment wall hydrant includes a reservoir, conduits containing an operating rod assembly and a service rod assembly, and a fluid outlet with a hose connector. The service rod assembly allows water supply to the hydrant to be shut-off from the front of the hydrant which allows servicing of the hydrant without requiring water shut-off to all or a portion of the water supply to the building. Embodiments include a vacuum relief dual check valve assembly at the fluid outlet which prevents backflow of water into the hydrant. Embodiments include a box which protects the hydrant controls.
