Abstract
A yard hydrant that facilitates the evacuation of water from therein. The wall hydrant has a standpipe having a drain port wherein the standpipe is coupled to a head casing that has a discharge conduit. An air line is mounted adjacent and to the drain port and extends from the drain port to an end that may be attached to a pressurized fluid source. Thus, when water remains in the standpipe even after a closure valve is closed, pressurized air is supplied through the air line and drain port into the standpipe to force retained water toward and out of the discharge conduit.
