Question
How do I adjust the pressure of the sprinkler head?  The pop ups in my front
yard(one zone only) spray the correct arc, but into the street.  How do I adjust to
decrease pressure and water lawn instead?

Answer
Hey Karen, if you look at the very center on the top of the head, you will notice either a small slotted or hex screw head. What you want to do is screw this screw clockwise (down) into the head, and it will decrease the distance the water stream will throw. If you screw it all the way down, it will actually turn off the water all together. Normally we will adjust this screw as the system is running(you might get a little wet) to better fine tune the spray distance. Good luck and have a great day.
