Sprinklers Won T Turn Off – It’s the height of summer and that means one thing – lawn watering season is in full swing. If you’re like most homeowners, your sprinkler system keeps your lawn green and lush despite the heat. If you’re like most people, you rely on your sprinkler system to keep your lawn green and healthy. But what do you do when your sprinklers won’t go off?
We’ll go over the main reasons why your launchers won’t shut down, and then we’ll get you up and running again.
Sprinklers Won T Turn Off
There are several reasons why a sprinkler system may not go off, such as dirty valves, problems with the timer, or a more complex mechanical problem.
How To Replace A Lawn Irrigation Sprinkler Valve
The first thing you need to do if your launchers won’t go off is check the timer. It’s possible that the timer was set longer than you intended, which explains why the launchers are still working. Check the timer settings to make sure they are configured correctly.
Sometimes the problem can be caused by the main water source. These problems can include improper opening of the valve, debris inside the valve, or a broken valve.
This can be a quick fix depending on the problem. If there is debris inside the valve, it should be flushed. If the valve does not open properly or appears broken, replace it.
How Much Does It Cost To Winterize A Sprinkler System?
One of the most common reasons why nozzles won’t turn off is because the valves are dirty or blocked. Over time, dirt and debris can accumulate in the valves, preventing them from closing properly. This is especially common in systems that use subsurface irrigation.
Clean the valves by turning off the power to your sprinkler system. Next, remove the valve cover and use a wire brush to clean out any dirt that might be blocking the valves. After cleaning the valves, replace the cover and start the system.
The control panel is the “brain” of your sprinkler system. It’s possible that the control panel just needs a reset. Check the control panel for error messages. If you see an error message, it usually tells you what the problem is and how to fix it. If you don’t see any error messages, you can try resetting the control panel.
Shut It Off! Turning Off And On A Well Water Source
Although not that common, it is possible that your controller’s transformer is not working properly. An expert or electrician can check this with a multimeter. Remember that water and electricity do not mix! If you do not know exactly what you are doing, we recommend that you call an expert to help you.
If your valves have been closed for a while, it is possible that they have trapped air. This may cause them to not function properly when restarted. To fix this, simply bleed each valve one at a time by opening the bleed screw until the water comes out.
If you’ve gone through all of these steps and your sprinkler system still won’t go off, it’s time to call a professional. A professional can diagnose the problem and get your sprinkler system back up and running in no time.

Sprinkler System Won’t Turn On
The time-saving sprinkler system you installed will help keep your garden lush, but a broken irrigation system can quickly cause problems for your backyard. Use the watering tips in this guide to learn what to do if your sprinklers won’t turn off.
Whether you have local sprinkler installers install your irrigation system or do it yourself, the basic components are the same. All automatic irrigation systems have:
If your system is stuck, don’t panic. While you may need to hire a professional, there are a few steps you can try to troubleshoot why your sprinklers aren’t going off first.
How To Replace Sprinkler Heads To Avoid Future Breaks
If you close the valve and the jets still work, that means your valve is faulty. The valve may have debris or it may not close properly. You need to change it.
Backflow prevention is another way to disable the system. Locate your backflow prevention program by looking for the green box, which is usually found near your property’s water meter.
If your sprinklers still won’t go off or your backflow prevention system is leaking, it may need to be repaired or replaced.
The Importance Of Irrigation Systems
If water stops flowing from the sprinklers after using the shut-off valve, go to the tester.
If it seems like it’s a particular sprinkler zone that won’t go off, there are a few ways you can troubleshoot.

How To Winterize Your Irrigation System So The Backflow Preventer Won’t Blow
Someone came to my house to winterize the sprinklers. He explained to me what he did: He said he shut off the sprinkler system’s main valve, turned on the compressor, and blew all the water out of the sprinkler lines. Also open the air valve to let air in but not water. After that I noticed that the air valve is slowly leaking water. I called the same guy again and he said the water is leaking because the main valve in the sprinkler system is faulty and I need to replace it.
Can someone tell me if the air valve is leaking water when the main sprinkler valve is closed, it needs to be replaced. Note that when the air valve was in the closed position and the sprinkler main valve was open, no water leakage occurred. Also, when I keep the sprinkler valve closed, if I also close the air valve, water starts coming from something attached above the air valve.
Probably no picture, but it sounds like the “connecting thing above the air valve” is a vacuum switch. The vacuum cleaner prevents water from flowing from the outside back into the main water line (and then into drinking water). It allows water from inside the water mains to pass through it with your home’s water pressure and forces the vacuum switch to open (water traveling in the opposite direction closes the valve and prevents your drinking water from contaminating it).
How To Adjust Orbit Lawn Sprinklers
It sounds like the sprinkler water line is leaking very slowly. And I’m assuming that the slow leak from the sprinkler water line is not enough to open the vacuum switch all the way and it just clears at that point (when the air valve is closed).
It’s not the air valve you have. This is called an anti-siphon valve. Inside there should be a blockage in the pipe coming from the house. Make sure it is closed. Again, this should be located inside your home and is usually a lever valve.
I’m not a plumbing expert or anything, but I have 3 houses and I’ve either built or installed irrigation systems for each house. I learned through the hard knocks of college.
How To Repair A Sprinkler
Consider a situation where a garden hose labeled “air valve” is connected to this spigot and the hose is used to fill the pool and left in the pool. The purpose of the anti-siphon valve is to prevent water from flowing back into the home water supply, which contaminates drinking water.
I think the air noise you are hearing is that you have removed all the water leaving an unbalanced pressure. Some irrigation systems have a “check valve” with a pressure relief screw. If you have one of these, you can release the pressure by turning the screw.
As an update: Next I would make sure the internal lever is still closed and open the opening you marked as the air valve and if you have underground valves for your launchers and they have a manual switch, turn it to see if the “leak” goes away. I’ve had this scenario before. Every year I blow my own sprinklers. But DO NOT leave the mechanical switch open. Do this just to see if the leak stops. If it stops, you have a simple pressure imbalance
