How to Adjust Sprinkler Valves
- 1). Turn on the sprinklers so that you can judge which valves need to be adjusted. Wear old clothes. You will get wet.
- 2). Look at the top of the valve and locate the twist knob that controls the valve setting.
- 3). Turn the knob to the right to lower the valve setting. This closes the valve more to reduce the amount of water coming through. Turn partially-closed valves to the left to raise the valve setting and allow more water to exit.
