Electric Sprinkler System: Turning Off Made Easy

how to turn off electric sprinkler system

Knowing how to turn off your electric sprinkler system is essential for maintenance, repairs, and winterization. Sprinkler systems are typically controlled by a controller or a switch located in the garage, mounted on an exterior wall, or near the water source. To turn off the system, simply turn the dial, knob, or switch to the off position. If the control panel is digital, it may have a “rain mode” button that can be used to turn the system off temporarily. For a long-term shut-off, the entire system can be powered down. It is important to refer to the user manual or manufacturer's website for specific instructions. After turning off the controller, the next step is to locate and close the shut-off valve, which is usually a ball valve with a lever handle located above or below ground near the water source. This process may vary depending on the type of sprinkler system and the manufacturer's specifications.

Turn off at the controller

Turning off your sprinkler system at the controller is a straightforward process. First, locate the controller. This is typically found inside your garage, mounted to an exterior wall. If you have a digital control panel, it may have a button to turn on "rain mode", which is a simple way to turn your system off while saving your settings. Otherwise, simply turn the dial or knob on the controller to the off position. If you have a faulty controller, it may be malfunctioning due to debris in the line or electrical issues. In this case, you may need to turn off the main water supply to your sprinkler system.

If you are turning off your sprinkler system for the winter, you will need to drain the remaining water from the pipes. This is a crucial step to winterizing your sprinkler system to prevent freezing and pipe damage. To do this, locate the shut-off valve, which is usually a ball valve with a lever handle. It can be located above or below ground. If it is above ground, it is typically found near the water source, which is usually near the house or garage. If the valve is underground, you will need to locate the valve box, which may be buried and could be oval or rectangular. Always call 811 before digging to ensure you do not hit any utility lines.

If your sprinkler system has check valves, you can lift the sprinkler heads to drain the remaining water. Once the system is drained, close the test cocks and valves. If your system does not have check valves, the process for draining the water will depend on the type of system. Some systems may have an automatic draining function.

It is important to note that turning off the controller will not stop the flow of water to the sprinkler system if there is a leak or if the controller is broken. In this case, you will need to shut off the water at the source or the main water supply.

Locate the shut-off valve

Locating the shut-off valve of an electric sprinkler system can be challenging, but it's important to know where it is in case of emergencies or for maintenance and repairs. Here are some tips to help you locate the shut-off valve:

First, understand that the shut-off valve may be located above ground or underground. It is usually installed near the backflow preventer or vacuum breaker. If it's an underground valve, it will likely be inside a valve box.

If you have the layout or documentation of your sprinkler system, refer to it to identify the different zones and the location of important parts, such as the controller and the valve box. The controller, or timer, will have wires connected to different valves, each responsible for a specific zone of the sprinkler system.

To physically locate the valve box, look for a bright green lid in your yard, especially near your home's water source. The lid will be covering the valve box, which houses the shut-off valve. If you can't find the valve box, try probing the ground about 6 to 12 inches deep with a long, flat-head tool.

In some cases, the main shut-off valve may be located inside your house, either in the basement or a crawl space. It is typically within 3 to 5 feet of where the main water pipe enters your home. If you can't find it inside, check outside near an outdoor faucet or water source. Outdoor shut-off valves are more common in warmer climates where freezing isn't a concern.

If you're still unable to locate the shut-off valve, consider contacting a local plumber or sprinkler specialist for assistance. They will be able to help you find the valve and provide guidance on any necessary repairs or maintenance.

Drain remaining water

Draining the remaining water from your sprinkler system is a crucial step in preparing it for winter or repairing it. The process of draining the water will vary depending on the type of sprinkler system you have. Here is a step-by-step guide to help you drain the remaining water from your sprinkler system:

  • Locate the shut-off valve: The shut-off valve is usually located near the water source, which is typically near the house, garage, or water meter. It can be above or below ground. If it is a newer system, the shut-off valve is likely a polyvinyl chloride (PVC) ball valve located in the parkway in front of the house, between the street and the sidewalk.
  • Turn off the water supply: Before draining the pipes, you must first turn off the water supply to the sprinkler system. This can be done by turning the shut-off valve handle perpendicular to the pipe or waterline it is attached to. This will shut off the water flow to the sprinklers.
  • Drain the water from the pipes: Now that the water supply is turned off, you can drain the remaining water from the pipes. This step is crucial to prevent freezing and pipe damage during winter. Some sprinkler systems may have an automatic draining function to simplify this process.
  • Lift the sprinkler heads: If your sprinklers have check valves, you can lift the sprinkler heads to drain any remaining water from them.
  • Close the test cocks and valves: Once the system is completely drained, remember to close the test cocks and valves to ensure that the system remains turned off.

Remember to always wear protective gear, such as gloves and eye protection, when working on your sprinkler system. If you are unsure about any part of the process or encounter any issues, it is best to contact a professional for assistance.

Prevent damage

Knowing how to turn off your sprinkler system is essential to prevent damage and costly repairs. Here are some steps you can take to prevent damage:

Locate the control panel

Most outdoor sprinkler systems have an indoor control panel, usually located in the garage or on an exterior wall. This is the "brain" of your sprinkler system, and turning it off will halt operations. If your control panel is digital, it may have a "rain mode" button, which is a simple way to turn off the sprinklers while saving your settings.

Turn off the water supply

You can turn off the water supply by locating the backflow device, which is usually found in your basement or on the exterior of your house. The backflow device has two valves; turn one of them upwards, and the water supply will be cut off.

Shut off the main water supply

If the above steps do not work, locate the main water supply line for your home, which is usually in the basement, yard, or utility closet. Here, you will find two levers – one for your home and one for your sprinkler system. Turn the lever for the sprinkler system 90 degrees from the pipes to shut off the water supply to the sprinklers.

Drain the pipes

If you are preparing your sprinkler system for winter, it is essential to drain the pipes to prevent freezing and pipe damage. Schedule a time for an expert to come and drain the pipes to ensure it is handled correctly.

Regular maintenance

Regular maintenance of your sprinkler system is crucial to prevent damage. Check for leaks or damage in the spring and begin the winterization process in autumn. Keep sprinkler heads and valve boxes free from debris to prevent clogs and ensure proper water flow.

By following these steps, you can effectively turn off your electric sprinkler system and prevent potential damage.

Prepare for winter

Preparing your electric sprinkler system for winter is essential to prevent water from freezing inside the pipes and damaging the system. Here are the steps you can take to get your sprinkler system ready for the winter:

Locate the Main Water Supply:

The first step is to find the main water supply line for your home, typically located in the basement or a utility closet. This line connects your home to the street water supply.

Identify the Sprinkler System Lever:

Once you've located the main water supply, you'll see two levers – one for your home's water supply and the other specifically for the sprinkler system. The sprinkler system lever is what you'll need to manipulate to control the water flow to the sprinklers.

Shut Off the Water Supply to the Sprinklers:

Turn the sprinkler system lever so that it is perpendicular (at a 90-degree angle) to the pipes. This action will cut off the water flow to the sprinklers. Ensure that the lever is secure and won't accidentally move back to the "on" position.

Drain the Sprinkler System:

To prevent water from freezing and bursting the pipes, it's crucial to drain the system. Some sprinkler systems have automatic flush valves that expel water each time the system is turned off. Check your system's user manual to see if it has this feature and ensure that the valves are working correctly. If your system doesn't have automatic drainage, you can use an air compressor to force the water out of the pipes. Ensure that the air compressor can produce an air volume of 30 to 50 cubic feet per minute (CFM) and a pressure of 40 to 80 pounds per square inch (PSI).

Insulate Above-Ground Components:

Protect any above-ground parts of your sprinkler system, such as spigots, pipes, and faucets, by insulating them with foam covers, pipe insulation, or even pool noodles. This extra layer will help shield them from the cold and potential damage.

Turn Off the Sprinkler Timer:

Finally, remember to switch your sprinkler timer or controller to the "off" setting. This step ensures that no part of the system accidentally activates during the winter, and it's an essential precaution to take before spring arrives.

It is recommended to winterize your sprinkler system in October, but do check your local guidelines to find out when a hard freeze is expected in your area. You can also consult a professional to ensure your sprinkler system is correctly prepared for winter and avoid any potential damage.
