If you want to ensure that your lawn irrigation system remains in optimal condition through the colder months, winterizing it is crucial. Taking the time to properly prepare your system for winter can help prevent costly repairs come spring. Here’s a detailed guide on how to winterize your irrigation system effectively.
1. Shut Off the Water Supply
The first step in winterizing your lawn irrigation system is to shut off the water supply. Locate the main shut-off valve for your system and turn it off to prevent water from flowing into the pipes.
2. Drain the Water from the Main Line
Next, drain any remaining water from the main line of your irrigation system. This can be done by opening the drain valve and allowing the water to flow out completely.
3. Close the Valves on the Backflow Preventer
Ensure that all valves on the backflow preventer are closed to prevent water from entering the system from the main water supply.
4. Prep the Air Compressor
Prepare your air compressor for use by checking the pressure settings and ensuring that it is in good working condition.
5. Connect the Air Compressor
Connect the air compressor to the irrigation system using the appropriate fittings and hoses.
6. Open Up the Blow-Out Port Valve
If your system is equipped with a blow-out port valve, open it to allow air to flow through the pipes.
7. Blow Out Each Sprinkler Zone Individually
Starting with the zone farthest from the compressor, blow out each sprinkler zone individually to remove any remaining water in the pipes.
8. Release Any Remaining Pressure in the Line
After blowing out all the zones, release any remaining pressure in the line by opening the drain valves or faucets.
9. Insulate Exposed Pipes
To protect your irrigation system from freezing temperatures, consider insulating any exposed pipes with foam insulation or heat tape.
10. Store Hoses Indoors
Don’t forget to disconnect and store any garden hoses indoors to prevent them from freezing and cracking.
11. Schedule a Professional Inspection
If you’re unsure about how to winterize your irrigation system or if you want to ensure that it’s done correctly, consider scheduling a professional inspection and maintenance service.
12. Monitor Weather Conditions
Throughout the winter months, keep an eye on weather forecasts and be prepared to take additional precautions if extremely cold temperatures are expected.
