If you have noticed that your sprinklers won’t turn off, you are not alone. This is a common issue that many homeowners face, and it can be frustrating to deal with. The good news is that there are several things you can do to fix the problem and get your sprinklers working properly again.
Understanding your sprinkler system is the first step to identifying the problem. Your sprinkler system is made up of several components, including the control panel, valves, and water supply. If any of these components are not working correctly, it can cause your sprinklers to stay on even when they are supposed to be off. Checking each of these components can help you identify the issue and take the necessary steps to fix it.
Inspecting the valves is another crucial step in fixing your sprinklers. Debris and dirt can accumulate in the valves over time, preventing them from closing properly. Cleaning the valves or replacing them if necessary can help your sprinklers turn off when they are supposed to. By following these steps and taking the necessary repair and maintenance measures, you can get your sprinkler system working properly again.
Understanding Your Sprinkler System
If you are experiencing an issue with your sprinklers not turning off, it is important to have a basic understanding of how your sprinkler system works.
A typical sprinkler system consists of a controller, valves, and sprinkler heads. The controller is the brain of the system, and it is responsible for sending signals to the valves to turn on or off the water flow to the sprinkler heads. The valves are located in the ground and are responsible for controlling the water flow to specific zones. Each zone is a specific area of your landscaping or garden that is watered by a designated set of sprinkler heads.
When you turn on your sprinkler system, the controller sends a signal to the valves to open, allowing water to flow to the sprinkler heads in the designated zone. Once the designated amount of time has passed, the controller sends a signal to the valves to close, stopping the water flow to the sprinkler heads in that zone.
If your sprinklers won’t turn off, it could be due to a malfunctioning valve or controller. It is important to identify the specific zone that is having issues and inspect the valves and sprinkler heads in that zone.
It is also important to note that a malfunctioning sprinkler system can waste a significant amount of water, which can be harmful to the environment and costly to your water bill. Therefore, it is crucial to address any issues with your sprinkler system as soon as possible.
By understanding the basics of how your sprinkler system works, you can more effectively troubleshoot and address any issues that arise with your sprinklers not turning off.

Leaks can also cause sprinklers not to turn off. If there is a leak in your sprinkler system, then water may continue to flow, causing your sprinklers to stay on. Check your sprinkler system for leaks and fix any that you find.
Finally, defective components in your sprinkler system can cause sprinklers not to turn off. If a solenoid or other component is defective, then your sprinklers may not turn off when they are supposed to. Check the components of your sprinkler system to ensure that they are working correctly.
By identifying the possible causes of sprinklers not turning off, you can troubleshoot and fix the issue quickly.
Checking the Control Panel
If your sprinklers won’t turn off, the control panel is one of the first places to check. The control panel is the device that controls the sprinkler system, and it may be called a timer or a controller.
The first thing to check is the battery. If the battery is dead, the control panel will not work properly. Check the battery and replace it if necessary.
Next, check the controller transformer. The transformer is what powers the controller, and if it is not working properly, the controller will not work either. Check the transformer and replace it if necessary.
Once you have checked the battery and transformer, check the control panel itself. Look for any loose or damaged wires, and make sure all connections are secure. If you find any loose or damaged wires, fix them or replace them as necessary.
Finally, check the programming on the control panel. Make sure the settings are correct and that the sprinklers are set to turn off at the appropriate time. If the programming is incorrect, adjust it accordingly.
By checking the control panel, you can often identify and fix the issue causing your sprinklers to not turn off. If you are still having issues after checking the control panel, there may be a more serious issue with your sprinkler system that requires professional help.
Inspecting the Valves
When your sprinklers won’t turn off, one of the first things you should check is the valves. Valves are responsible for controlling the flow of water through your sprinkler system. If a valve is dirty, faulty, or broken, it can cause your sprinklers to stay on even when they’re supposed to be off.
Here are some steps to inspect your valves:
- Locate the valves: Valves are typically located in a valve box buried underground. Use a shovel to dig around the valve box until you can see the lid. Remove the lid to access the valves.
- Check the valves for trapped air: Sometimes air can get trapped in the valves, preventing them from closing properly. To release the trapped air, turn the bleed screw on top of the valve counterclockwise until water starts to flow out.
- Inspect the valves for dirt: Dirt can accumulate inside the valves, preventing them from closing properly. Use a soft brush to clean the inside of the valve. Be careful not to damage any of the valve parts while cleaning.
- Check for faulty or broken valves: If the valve won’t close even after cleaning it, it may be faulty or broken. You can test the valve by manually turning the solenoid or the bleed screw. If the valve still won’t close, it’s time to replace it.
- Inspect the backflow valve: The backflow valve prevents water from flowing back into your home’s water supply. If the backflow valve is faulty, it can cause your sprinklers to stay on. Check the backflow valve for any signs of damage or wear. If you notice any issues, it’s time to replace the valve.
- Check the main water supply valve: If none of the valves seem to be the problem, it’s time to check the main water supply valve. The main water supply valve is typically located near your water meter. Make sure the valve is fully open. If the valve is closed or partially closed, it can cause your sprinklers to stay on.
Inspecting your valves is an important step in troubleshooting why your sprinklers won’t turn off. By following these steps, you can identify and fix the problem quickly and efficiently.
Dealing with Water Supply Issues
If your sprinklers won’t turn off, it could be due to a water supply issue. Here are some things you can check:
