Abstract
A sprinkler head apparatus includes two separately molded members secured together independently of a water volume control member. A number of selectively removable devices that withstand the forces of water in irrigation systems and can be easily removed by the user without additional hardware are situated at the entry point of water outflow channels to provide the user directional control of the water sprayed from the apparatus. Registration elements are provided to ensure the proper alignment between the members of the apparatus. Correspondingly, indicia located at upper and lower external surfaces of the assembled apparatus reduce or eliminate the need to disassemble the apparatus or intermittently test the water spray pattern to ensure proper installation of the apparatus. Preferred methods for assembling the apparatus, for directing the outflow of water, and for aligning the members of the apparatus are disclosed.
