Step-by-Step Guide on How to Winterize Your Irrigation System
Step 1: Shut Off the Main Water Supply
Locate and close the irrigation system’s main valve to stop water flow.
Step 2: Drain the Water from the System
Manual Drain Method: Open designated drain valves to release water.
Automatic Drain Method: Utilize self-draining valves if your system has them.
Blowout Method: Use compressed air to force out remaining water (recommended for complete drainage).
Step 3: Turn Off and Protect the Irrigation Controller
Set your irrigation controller to "winter" or "off" mode.
Remove batteries if applicable to prevent corrosion.
