Turning off the water supply to your sprinkler system is an essential task for maintaining its longevity and efficiency. Whether you’re preparing for seasonal changes, performing maintenance, or troubleshooting issues, understanding how to properly shut off the water can prevent potential damage and unnecessary water waste.
In this guide on how to turn off water to sprinkler system, we will walk you through the steps needed to safely and effectively turn off the water in your sprinkler system, ensuring that you have a clear and easy-to-follow process.
Why is it Important to Turn Off the Water to the Sprinkler System?
Before diving into the steps on how to turn off water to your sprinkler system, let’s first discuss why this task is crucial. Turning off the water supply prevents water from flowing through the system, which helps reduce wear and tear on the pipes, valves, and other components. It also allows for any necessary repairs or maintenance work to be done without risking damage from pressurized water.
Moreover, turning off the water supply can prevent potential flooding in case of a malfunction or broken pipe in your sprinkler system. By shutting off the water before performing any work on the system, you can avoid costly repairs and protect your property from water damage.
8 Steps on How to Turn Off Water to Sprinkler System
Step 1: Locate the Main Shut-Off Valve
The first step in turning off the water in your sprinkler system is to locate the main shut-off valve. This valve is typically found near the water source that feeds your irrigation system, often in a basement, garage, or outside near the meter.
Look for a round or oval handle, which may be made of brass or plastic, and ensure it is clearly marked as the irrigation supply. If you’re unsure of its exact location, consult the blueprints of your property or ask a professional for assistance. Familiarizing yourself with the valve will make the process easier when it’s time to turn off the water.
Step 2: Turn Off the Valve
Once you have located the main shut-off valve, turn it clockwise to close it fully. This will stop the flow of water to your sprinkler system. If the valve is tight or difficult to turn, consider using a wrench for better leverage.
Note that some valves may have a lever instead of a handle, which should be flipped into the off position. Whichever type of valve you have, ensure that it is completely closed before proceeding with any work on your sprinkler system.
Step 3: Disconnect Power from Controller
Before working on your sprinkler system, it’s essential to disconnect the power from the controller to prevent any automatic watering cycles from starting. Depending on your specific controller model, this may involve unplugging it or turning off the circuit breaker that supplies power to it.
Ensure that the controller is completely powered off before proceeding.
Step 4: Drain the System
After turning off the main shut-off valve and disconnecting power from the controller, the next step is to drain the system to prevent any water from remaining in the pipes. Begin by locating the drain valves, which are usually situated at the lowest point of your sprinkler system. Open these valves to allow the water to escape. If your system is equipped with an automatic drain feature, it may drain itself once the shut-off valve is closed.
Additionally, if your sprinkler system utilizes a backflow preventer, ensure you open the air relief valve to allow air in, which will facilitate complete drainage. Allow the system to drain fully to avoid potential freezing or damage during colder months. Once you see no water exiting from the drain valves, you can proceed with further maintenance or repairs as needed.
Step 5: Check for Any Remaining Water
After draining the system, it’s crucial to check for any remaining water to prevent potential damage. Begin by checking the main shut-off valve and its surrounding area for any leaks or signs of moisture. If you notice any, ensure that the valve is fully closed and fix any leaks before proceeding.
Next, inspect all sprinkler heads and pipes for water. If you spot any, use a towel or cloth to dry them off completely. It’s essential to remove all water from the system to avoid freezing during colder months.
Step 6: Perform Maintenance or Repairs
With the water turned off and the system drained, now is the ideal time to perform any necessary maintenance or repairs on your sprinkler system. Start by inspecting all components, including sprinkler heads, pipes, and connections, for any signs of wear, damage, or blockages. If you find any broken or malfunctioning parts, replace them to ensure optimal performance when the system is turned back on.
Additionally, take this opportunity to clean the sprinkler heads and filters, removing dirt and debris that might impede water flow. Regular maintenance not only prolongs the life of your sprinkler system but also improves its efficiency, helping you keep your landscape healthy and vibrant. Once all maintenance tasks are complete, you can proceed with the next steps in your shutdown process.
Step 7: Close Drain Valves and Turn on Water
After completing any necessary maintenance or repairs, it’s time to close the drain valves and turn the water back on. Begin by closing all drain valves that were opened previously to allow the system to drain. Once these are fully closed, turn the main shut-off valve counterclockwise to open it and allow water to flow into your sprinkler system again.
Note that some systems may require you to prime the pump or bleed air from the pipes before turning on the water completely. If this is the case for your system, follow manufacturer instructions carefully to avoid damage.
Step 8: Power Up the Controller and Run Test Cycles
Once the water is turned on and flowing freely through your system, it’s time to power up the controller again. Connect the power supply or turn on the circuit breaker to restore power to the controller. Check all settings and ensure that they are back to their original programming.
Finally, run a test cycle by turning on each zone individually and checking for proper functioning. If everything looks good, your sprinkler system shutdown process is complete, and you can enjoy a well-maintained landscape without any risk of water damage or irrigation malfunctions.
Additional Tips
Seasonal Checks:
Regularly inspect your sprinkler system at the beginning and end of each season to catch any issues before they become significant problems. Look for cracks, leaks, or wear and tear in the components.
Winterization Techniques:
In colder climates, consider using compressed air to blow out the system to ensure all water is removed, preventing freeze damage. Always follow manufacturer guidelines for winterizing techniques appropriate for your specific system.
Soil Moisture Awareness:
Monitoring soil moisture levels can help you adjust your watering schedule and prevent overwatering, ensuring your plants are healthy while conserving water.
Adjusting Sprinkler Heads:
Regularly check that your sprinkler heads are adjusted correctly to avoid overspray onto sidewalks or driveways, which can waste water.
Rain Sensor Installation:
Consider installing a rain sensor on your system. This device will automatically skip watering cycles during precipitation, promoting water conservation and efficiency.
Consulting Professionals:
When in doubt, or for major repairs, do not hesitate to contact a professional irrigation technician. Their expertise can ensure that your system is running optimally and efficiently.
Following these steps and additional tips on how to turn off water to sprinkler system will help you properly shut down your sprinkler system for the season, preventing costly repairs and water waste. Regular maintenance and proper winterization techniques are crucial to keep your sprinkler system functioning correctly for years to come.
Frequently Asked Questions
Q: How Often Should I Shut Down My Sprinkler System?
It’s recommended to shut down your sprinkler system at least once a year, ideally before the first freeze of the season. This ensures that any remaining water is drained to prevent potential damage during colder months. It’s also a good idea to shut down the system before any extended periods of inactivity, such as during a vacation.
