If you’re experiencing trouble with your Hunter sprinkler system not turning off, you’re not alone. This is a common problem that can be caused by a variety of issues, from faulty valves to damaged diaphragms. Fortunately, there are steps you can take to troubleshoot and fix the problem, so you don’t have to waste water or worry about your lawn getting over-watered.
One of the first things to check is the rain sensor. If it’s not turning off the sprinklers when it’s raining, you may need to manually test its operation. You can do this by using the One Touch Manual Start and pressing the test button on the sensor during the Manual All stations cycle. If the rain sensor is working properly, it should interrupt watering. If it doesn’t, you may need to replace the sensor or troubleshoot other issues, such as wiring or controller problems.
Another common culprit for sprinklers that won’t turn off is faulty valves. Hunter valves require at least 20 PSI to close, so if the pressure is too low, the valve may not be able to shut off. You’ll also want to check the solenoid specifications, as these can affect the valve’s ability to close properly. If the valve is damaged or worn, you may need to replace it to fix the problem.
Possible Causes
If your Hunter sprinkler won’t turn off, there could be several possible causes. In this section, we will discuss some of the most common reasons why your sprinkler system might fail to turn off.
Faulty Solenoid
One of the most common reasons why your sprinkler system won’t turn off is a faulty solenoid. The solenoid is an electromagnetic valve that controls the flow of water to the sprinkler heads. If the solenoid is damaged or worn out, it may fail to close properly, causing water to continue flowing to the sprinkler heads.
To check if the solenoid is faulty, you can use a multimeter to test the electrical continuity of the solenoid. If the solenoid is not working correctly, you will need to replace it with a new one.
Broken Sprinkler Head
Another possible cause of a sprinkler system that won’t turn off is a broken sprinkler head. If a sprinkler head is damaged or broken, it may fail to close properly, causing water to continue flowing to the sprinkler heads.
To check if a sprinkler head is broken, you can inspect the head for any visible damage or leaks. If you find a broken sprinkler head, you will need to replace it with a new one.
Defective Controller
A defective controller can also cause your Hunter sprinkler system to fail to turn off. If the controller is not working correctly, it may fail to send the signal to turn off the sprinkler system.
To check if the controller is defective, you can inspect the controller for any visible damage or error messages. If you find a defective controller, you will need to replace it with a new one.
In conclusion, if your Hunter sprinkler won’t turn off, it could be due to a faulty solenoid, broken sprinkler head, or defective controller. By identifying the cause of the problem, you can take the necessary steps to fix your sprinkler system and prevent future problems.
Troubleshooting Steps
If you’re experiencing an issue with your Hunter sprinkler system not turning off, there are a few troubleshooting steps you can take to resolve the problem. Follow the steps below to identify and fix the issue:
Turn Off Water Supply
The first step is to turn off the water supply to your sprinkler system. You can do this by turning off the main water supply valve or the “off” switch on the controller. Once the water supply is turned off, you can begin troubleshooting the issue.
Check for Debris in the Valve
One common cause of a sprinkler system not turning off is debris in the valve. To check for this issue, remove the valve cover and inspect the valve for any debris or dirt. If you find debris, clean the valve and reassemble it.
Inspect the Solenoid
Another possible cause of a sprinkler system not turning off is a faulty solenoid. To check for this issue, remove the solenoid from the valve and inspect it for any damage or wear. If the solenoid is damaged, replace it with a new one.
Examine the Sprinkler Head
If the above steps don’t resolve the issue, the problem may be with the sprinkler head. Inspect the sprinkler head for any damage or wear, and replace it if necessary.
Test the Controller
Finally, if none of the above steps resolve the issue, test the controller. Check the programming and settings to ensure they are correct, and test the controller to ensure it is functioning properly. If the controller is faulty, replace it with a new one.
By following these troubleshooting steps, you should be able to identify and resolve the issue with your Hunter sprinkler system not turning off.
