Abstract
One embodiment provides a helical restrictor insert for a sprinkler nozzle. The helical thread of the insert imparts a helical swirl into the water stream which changes the flow and distribution pattern of the water leaving the nozzle. The position of the end of the helical thread can be adjusted to direct a portion of the water stream downward, close to the sprinkler head without adversely affecting the nearby turf.
