ABSTRACT:
A soil-mounted hydrant selectively positionable above the ground level to distribute an irrigation fluid to its environment is described. A distributing aperture in the side wall on the upper portion of a cylindrical hydrant housing is closable to a desired degree by a hollow cylindrical cap member that is threadable into the interior of the hydrant housing. The threaded cap is captured within the interior of the housing by means of a limit pin disposed above the distributing aperture, such pin contacting the aperture-blocking portion of the cap when such cap is threaded outwardly to an upper limit, in which position the aperture is fully exposed. A longitudinal bore extends completely through the cap for shunting a portion of the irrigation fluid in an upwardly directed path while the hydrant is below ground level, such bore terminating in a nozzle for saturating the surrounding soil with a fine jet-like spray to facilitate the upward movement of the hydrant out of the ground. The upper end of the cap is upwardly and inwardly tapered to further facilitate the removal of the hydrant from the ground.
