Winterize Your Hunter Pro-C Sprinkler System: A Step-by-Step Guide to Avoid Costly Repairs
What To Know
- Once all sprinkler lines have been blown out, blow out the main line by connecting the air compressor hose directly to the controller’s test port.
- Bleed the system by opening the bleed valves and running the sprinklers for a few minutes.
- Store the controller in a warm, dry location, such as a basement or garage.
As the cold season approaches, it’s essential to winterize your Hunter Pro-C sprinkler system to protect it from freezing and potential damage. This comprehensive guide will provide you with step-by-step instructions on how to properly winterize your system, ensuring its longevity and optimal performance come spring.
Understanding the Hunter Pro-C Sprinkler System
The Hunter Pro-C sprinkler system is a sophisticated irrigation solution that offers numerous customizable features. It consists of a central controller, valves, sprinklers, and sensors. Understanding the system’s components and their functions is crucial for effective winterization.
Materials Required
Before starting the winterization process, gather the following materials:
- Air compressor
- Blowout plug
- Anti-freeze solution
- Rags or towels
- Screwdriver (optional)
Step-by-Step Winterization Instructions
1. Turn Off Water Supply
Locate the main water supply valve and turn it off to prevent water from flowing into the system.
2. Open Bleed Valves
Open all bleed valves located on the valves and sprinklers to release any remaining water.
3. Install Blowout Plug
Attach the blowout plug to the lowest point of your system, usually the drain valve. This will provide an outlet for compressed air to escape.
4. Connect Air Compressor
Connect the air compressor to the blowout plug and set the pressure to 30-40 PSI.
5. Blow Out Sprinkler Lines
Start blowing out the sprinkler lines one zone at a time. Begin at the farthest zone and work your way back towards the controller. Hold the air compressor hose over each sprinkler head and allow the compressed air to force out the remaining water.
6. Blow Out Main Line
Once all sprinkler lines have been blown out, blow out the main line by connecting the air compressor hose directly to the controller’s test port.
7. Add Anti-Freeze
If desired, pour anti-freeze solution into the bleed valves on the valves and sprinklers to provide additional protection against freezing.
8. Close Bleed Valves
Close all bleed valves to prevent air from entering the system.
Troubleshooting Common Issues
- Frozen Sprinkler Heads: If sprinkler heads freeze despite winterization, manually thaw them using warm water or a heat gun.
- Leaking Valves: If valves leak after winterization, tighten the packing nuts or replace the valve diaphragms.
- Air in the System: If the system does not operate properly in the spring, air may have entered during winterization. Bleed the system by opening the bleed valves and running the sprinklers for a few minutes.
Tips for Successful Winterization
- Winterize the system as early as possible before freezing temperatures occur.
- Use a high-quality air compressor with sufficient pressure.
- Thoroughly blow out all sprinkler lines and the main line.
- Consider using anti-freeze solution for added protection.
- Store the sprinkler controller and any accessories in a warm, dry location.
Re-Opening the System in Spring
When spring arrives, follow these steps to re-open your Hunter Pro-C sprinkler system:
- Turn on the main water supply valve.
- Close all bleed valves.
- Manually inspect the sprinkler heads for damage.
- Run the sprinklers for a few minutes to flush out any remaining anti-freeze or debris.
Takeaways: Preparing Your Sprinkler System for Winter
By following these comprehensive winterization instructions, you can effectively protect your Hunter Pro-C sprinkler system from the harsh effects of winter. With proper care, your system will be ready to provide optimal irrigation performance when the warm weather returns.
Questions You May Have
Q: How often should I winterize my Hunter Pro-C sprinkler system?
A: Winterize the system once a year before freezing temperatures occur.
Q: Can I use a wet/dry vacuum to blow out my sprinkler lines?
A: No, a wet/dry vacuum is not suitable for blowing out sprinkler lines. Use an air compressor with sufficient pressure.
Q: What is the best way to store the sprinkler controller during winter?
A: Store the controller in a warm, dry location, such as a basement or garage. Remove the batteries and store them separately.
