As temperatures drop, it's crucial to prepare your irrigation system for the colder months to prevent costly damage and ensure it functions properly in the spring. Winterizing your system helps avoid frozen pipes, cracked valves, and other weather-related issues. Follow this step-by-step guide to safeguard your irrigation system before winter sets in.

1. Shut Off the Water Supply

The first step in winterizing your irrigation system is to turn off the water supply. Locate the main shut-off valve and close it to prevent water from flowing through the pipes during freezing temperatures.

Pro Tips:

• Ensure the shut-off valve is properly insulated to prevent freezing.
• If your system has a backflow preventer, make sure to drain it as well.

2. Drain the Irrigation Lines

Removing excess water from the irrigation lines is essential to prevent freezing and pipe bursts.

Three Common Drainage Methods:

• Manual Drain Method – Open all valves and allow gravity to drain the water.
• Automatic Drain Method – Some systems automatically release excess water when pressure drops.
• Blow-Out Method – Use compressed air to force water out of the pipes (best done by professionals).

3. Protect Valves, Pipes, and Sprinkler Heads

Once the water is removed, take extra steps to protect your system's components from harsh winter conditions.

Protection Tips:

• Wrap exposed pipes with insulation tape or foam covers.
• Remove and store removable sprinkler heads indoors.
• Cover above-ground valves with insulating covers to prevent cracking.

4. Deactivate the Irrigation Controller

If your system has an automatic controller, be sure to turn it off or set it to "rain mode" to prevent unnecessary operation.

Why This Matters:

• Prevents the system from trying to activate during winter months.
• Saves energy and extends the lifespan of the controller.

5. Schedule a Professional Inspection

For best results, consider having a professional inspect and winterize your irrigation system. They can ensure all components are properly prepared and address any maintenance issues before winter arrives.
