Prepare for the Freezing Season

1. Turn off the Water Supply:

   Shut off the main water supply to the irrigation system. This helps prevent water from freezing in the pipes.

2. Drain the System:

   Open drain valves and drain any remaining water from the system. Use manual drain valves or automatic drain valves if your system has them.

3. Disconnect and Store Hoses:

   Disconnect hoses and store them in a dry place. Water left in hoses can freeze and cause damage.

4. Protect Backflow Preventer:

   If you have a backflow preventer, insulate it using a cover or insulation material to prevent freezing.

5. Insulate Exposed Pipes:

   Wrap exposed pipes with insulation to protect them from freezing temperatures.

6. Clear Irrigation Lines:

   Use compressed air to blow out any remaining water from the irrigation lines. This step is crucial to prevent freezing and damage.

7. Check and Adjust Timers:

   Adjust your irrigation system timers to accommodate seasonal changes. Consider reducing watering frequency during the winter months.

8. Inspect and Repair:

   Inspect the entire system for any leaks, damage, or worn-out components. Make necessary repairs before winter sets in.

9. Cover Valve Boxes:

   If your system has valve boxes, cover them to protect against debris and freezing temperatures.

10. Mark and Map Components:

    Before closing the system, mark the location of various components and map the irrigation system layout. This makes it easier to locate and inspect components in the spring.

Remember, the specific steps may vary based on the type of irrigation system you have. Always refer to the manufacturer’s guidelines for your particular system.
