Protecting Your Irrigation System This Winter
Irrigation system winterization is crucial for homeowners in cold climates. It prevents costly damage and ensures your system is ready for spring.
Here are the key steps:
- Shut off the water supply and insulate pipes.
- Turn off the timer on automatic systems.
- Drain the water using manual, automatic, or blow-out methods.
- Insulate above-ground components like valves and backflow preventers.
Winterizing your irrigation system protects it from freezing temperatures, which can cause pipes to crack and valves to break. This simple maintenance can save you from expensive repairs and keep your system running efficiently for years. Whether you do it yourself or hire a professional, taking these steps now will help your landscape thrive when the warm weather returns.
Why Winterize Your Irrigation System?
Winterizing your irrigation system is essential for several reasons. It helps prevent freezing, avoid costly repairs, and maintain system longevity. Let’s explore these benefits.
Prevent Freezing
When temperatures drop, any water left in your irrigation system can freeze. Water expands when it freezes, which can cause pipes to crack and sprinkler heads to break. By winterizing your system, you remove this water, reducing the risk of damage.
Avoid Costly Repairs
Repairing a damaged irrigation system can be expensive. Cracked pipes and broken valves often require professional repair services. By taking the time to winterize, you can save money by avoiding these costly repairs.
“Your goal isn’t water removal, it’s room for water expansion when it freezes.” – Reddit
Maintain System Longevity
Regular maintenance, including winterization, extends the lifespan of your irrigation system. A well-maintained system operates more efficiently and lasts longer, providing consistent water to your plants year after year.
Winterizing your irrigation system is a small investment of time and money that pays off in the long run. It’s a crucial step to ensure your system remains in top shape, ready to keep your landscape beautiful when spring arrives.
Next, we will explore the steps to winterize your irrigation system effectively.
Steps to Winterize Your Irrigation System
Step 1: Shut Off the Water Supply
First, shut off the water supply to your irrigation system. Locate the main shut-off valve, usually found near the water meter or the backflow prevention device.
To protect the valve from freezing, wrap it with foam insulation tape and cover it with a plastic bag. This helps to keep the cold air out and prevents any potential damage from freezing temperatures. If you don’t have a main shut-off valve, consider installing one as a preventative measure.
Step 2: Turn Off the Timer
If you have an automatic irrigation system, you’ll need to turn off the timer or controller. Most controllers have a “rain-mode” setting that stops the valves from activating but keeps your programming intact. This means your start times, valve run times, and other settings will remain saved.
For added precaution, if your controller activates a pump, disconnect the wires connected to the Master Valve (MV) and common terminals. This prevents accidental activation, which could cause overheating.
Step 3: Drain the Water
Next, you need to drain the water from the pipes and sprinklers to prevent freezing and expansion, which can damage your system. There are three common methods to do this:
Manual Drain Method:
- Shut off the water supply.
- Open the manual drain valves to let the water flow out.
- Drain the backflow device by opening its valves.
Automatic Drain Method:
- Activate the system to relieve pressure.
- The automatic drain valves will open and release the water.
Blow-Out Method:
- Connect an air compressor to the irrigation system using a coupler.
- Gradually increase the air pressure (do not exceed 80 PSI for PVC pipes or 50 PSI for polyethylene pipes).
- Open each zone one at a time, starting with the farthest from the compressor, until all water is expelled.
Safety Tip: Avoid standing near active sprinkler heads during the blow-out process.
Step 4: Insulate Above-Ground Components
Lastly, insulate any above-ground components such as backflow preventers and valves. Use foam covers or insulation tape to wrap these parts, ensuring they are protected from harsh winter conditions.
Be careful not to block air vents and drain outlets on backflow preventers. Proper insulation helps prevent freezing and extends the life of your irrigation system.
By following these steps, you can effectively winterize your irrigation system and protect it from winter damage.
Next, we will discuss the various methods for draining your irrigation system in more detail.
Methods for Draining Your Irrigation System
When it comes to irrigation system winterization, draining the water from your system is crucial. There are three main methods: manual drain, automatic drain, and the blow-out method. Each method has its own steps and considerations.
Manual Drain Method
The manual drain method is straightforward and involves a few simple steps:
- Shut off the water supply to the irrigation system.
- Locate the manual drain valves at the ends and low points of the piping.
- Open all the valves to let the water flow out.
- Drain the backflow device by opening its valves.
If your sprinklers have check valves, raise the sprinkler heads to allow water to drain out. Once the system is fully drained, close all the valves.
Automatic Drain Method
For systems equipped with automatic drain valves, the process is even easier:
- Turn off the water supply to the system.
- Briefly run one of the sprinkler heads to relieve the water pressure in the system.
- The automatic drain valves will open and release the remaining water.
You may still need to drain the water between the shut-off valve and the backflow device manually. If your sprinkler heads have check valves, empty them separately.
Blow-Out Method
The blow-out method uses compressed air to force water out of the irrigation system. This method is effective but requires caution:
- Shut down the water supply and connect an air compressor to the irrigation system using a coupler.
- Find the sprinkler station farthest from the compressor and turn it on.
- Close the backflow valves.
- Slowly open the valve on the compressor to gradually add air pressure. Do not exceed 80 PSI for PVC pipes or 50 PSI for polyethylene pipes.
- Once you see water coming through, activate each zone one at a time, starting with the farthest from the compressor.
- Shut off each zone when the spray of water ends.
- When all zones are clear, disconnect the compressor and release any remaining air pressure from the system.
- Finally, open and close the valves on the backflow device and manual drain valves to release any pent-up air pressure.
Safety Tip: Always wear safety glasses and avoid standing near active sprinkler heads during the blow-out process to prevent injury.
By understanding and using these methods, you can effectively drain your irrigation system and protect it from winter damage. Next, we’ll explore the benefits of hiring professional winterization services and how to find the right provider.
