Lawn Sprinkler Repair Frequently Asked Questions


Why won’t my lawn sprinklers turn on? The reason why your lawn sprinkler system will not turn on can be determined by two quick tests. First, locate one of the irrigation valves and turn the solenoid counter-clockwise. If the valve opens and sprinklers turn on, your valve is working and you’ll need to check the controller and wiring. If the valve did not turn on the sprinklers, the water to the valves is still off and may require further service. For that, it is recommended to schedule an appointment with a licensed irrigation contractor.

Why won’t my lawn sprinklers turn off? Lawn sprinklers that won’t turn off is very common problem. When valves wear out, they can stick open, stick closed or they can leak. Good news is, you can shut-off the water line that supplies the irrigation system without shutting-off water to the whole house. To do this, locate the main water shut-off for your house. There should be a separate pipe that branches off from the main water line. That pipe goes to the valve box containing your irrigation valves. It should have its own shut-off. Turn the handle to the off position. That will stop your irrigation system from running and allow you to contact a professional to diagnose and repair the problem.
