    There should be dials or knobs you can move around to adjust the spray nozzle.
  • Question
    What do I do if part of one quadrant isn't working. Some of the sprinkler heads work, but several of them just trickle from the head. What is the problem?
    Community Answer
    Your line feeding that quadrant could be broke or have debris in it. Do you have any wet areas that are pooling up when the system is running? If so, this could show you that that is the problem.

  • Question
    How do I repair the sprinkler valves?
    Community Answer
    The sprinkler valves have a little notch on the right hand side. Try adjusting the valve by twisting it or greasing it up a few times. This might take the place of a repair.

  • Question
    My sprinkler head still runs after I shut off the water. How do I stop this?
    Community Answer
    If you mean that the head just continually leaks, it's most likely a faulty diaphragm. Go to YouTube and look up how to change it on your system. It is actually pretty easy. Just have a screwdriver and paper towel to start. Turn off your system and the water supply to the system before starting.

    Look for anything that might be obstructing the sprinkler head's path. If you don't find an obvious blockage, try disassembling and reassembling the head and see if that helps. This will give you a closer look at the track and rotor mechanism.
  • Question
    What causes a sprinkler head to blow off when the water is turned on?
    Community Answer
    Chances are, mischievous troublemakers have glued the sprinkler holes closed and caused the pressure to build up until the head blows off.
  • Question
    What would make water not come out of my sprinklers when turned on?

    The two most likely causes are a bad connection or a blockage. Try tightening the sprinkler head on the riser, or applying a layer of thread seal tape to make sure the connection is secure. If that doesn't do the trick, the problem could be a clog somewhere in the water line. In this case, you'll want to remove the sprinkler head and flush the water from the line for 30-60 seconds to remove dirt and any other debris that has ended up inside.

    Look for a bad connection between the sprinkler head and rise. A quick hand-tightening or a layer of thread seal tape should resolve the issue.
