ABSTRACT OF THE DISCLOSURE Improvements are provided in a sprinkler head assembly including a hollow sprinkler head assembly tube, a sprinkler tip secured in the upper portion of that tube and a valve secured in the lower portion of the hollow sprinkler head assembly. The means for retaining the sprinkler tip within the hollow sprinkler head assembly is a securing structure which depends from the sprinkler tip, (e.g., a central tube having an internally threaded bore, the tube having a slit through the walls at its lower end forming bifurcated portions provided with a pair of wings, each having an upwardly facing abutting shoulder thereon), retainers within the upper portion of the hollow sprinkler head assembly on its inner wall, (e.g., a downwardly fac- ing abutting shoulder spaced downwardly from the upper end of the tube) and an actuator for urging the securing structure into engagement with the retainers (e.g., a screw engaged within the bore which when screwed down- wardly, spreads the wings, thus engaging the wing shoulders under the tube shoulders and securing the tip body portion in position). By suitable adjustments, the position of the valve relative to the seat is controlled, thus controlling the amount of water passing through the valve between the valve head and the seat.
