A spray head body extension that is screwed onto the upper end of a spray head body after the cap is removed. The cap is then reinstalled on the extension to raise the effective height of the a spray head body and its spray pattern. The spray head body extension permits fast, easy raising of a sunken in-ground spray head without having to dig below the spray head's water supply. A one-piece embodiment uses a compressible gasket to enable the extension to be tightened to the body until the internal guide splines of both the extension and body are aligned. A set screw can be employed to preserve alignment when the cap is reinstalled. An alignment tool helps align the splines of the extension to the body during installation. A multi-piece embodiment enables the extension to be aligned to the body before a separate collar nut is tightened.
