ABSTRACT:
A sprinkler system employs an articulated riser for adjustable sprinkler head positioning. The system allows for positioning each sprinkler head to compensate for ground irregularities by adjusting the position of the riser. The riser may be supplied for field use in assembled condition for direct fixed connection to T joints on the water main without excess ground digging. This substantially reduces part count for field use and system installation time. The joints of the riser provide leakproof movable connections which allow for the position adjustments of the riser and connected head.
