Pop-up sprinkler nozzles come in a variety of fan widths, from 30 degrees — for selective watering — all the way to 360 degrees. If your nozzle has a fan width less than 360 degrees, and it goes out of alignment, or you change the garden it’s watering, changing the direction of the fan is a simple task. It helps if you have a sprinkler pull-up tool to pull the sprinkler head out of the ground and keep it elevated while you work. If you don’t have one, a pair of locking pliers will also work.
