A sprinkler head of modern design is enclosed within a closed split housing that includes oppositely disposed wall sections connected to a base. Snap action springs selectively cause the outward rotation of the wall sections so that the wall sections become inverted and forcefully raise the base up off the ground. This elevates the sprinkler head above the ground and increases the irrigation efficiency thereof. A wall section of the housing carries indicia thereon indicating the name and location of a residence. With a closed housing placed on a lawn ground surface, the indicia becomes visible.
