Winterizing your sprinkler system is crucial for preventing costly damage and repairs caused by freezing water. By blowing out your sprinkler system before winter, you can ensure that all the water is forced out of the pipes, reducing the risk of freezing and subsequent damage.
Key Takeaways:
- Blowing out your sprinkler system before winter is essential to prevent water from freezing inside the pipes.
- The blow out method uses high pressure air to force all the water out of the system.
- Start by shutting off the main water supply and draining any remaining water.
- Attach an air compressor with a minimum volume of 30-50 cubic feet per minute (cfm) and pressure at 40-80 pounds per square inch (PSI).
- Blow out the sprinklers starting with the farthest zone from the mainline and gradually increase the pressure to the recommended PSI for your system.
- Close each sprinkler head or zone once the water spray stops, and release any pent-up air pressure from the backflow device valves.
- Insulate above-ground fixtures to further protect your sprinkler system from freezing.
Why Blow Out Your Sprinkler System?
Before winter arrives, it’s essential to winterize your sprinkler system to protect it from freezing temperatures and potential water damage. One of the most effective methods of winterization is blowing out your sprinkler system. By using high-pressure air, this process removes all the water from the system, preventing any residual water from freezing and causing costly damage.
The Risks of Not Winterizing
When winter arrives, the water left in your sprinkler system can freeze, expand, and burst the pipes. This can lead to leaks, pipe ruptures, and extensive damage to your irrigation system. Not only will you have to repair or replace the damaged pipes, but you may also need to address any resulting flooding or water damage to your property. By neglecting to winterize your sprinkler system, you risk expensive repairs and disruptions to your irrigation system in the spring.
The Benefits of Professional Winterization
While you can attempt to blow out your sprinkler system yourself, it is advisable to hire a professional sprinkler winterization service. These experts have the knowledge, experience, and equipment to ensure a thorough and effective blowout. They will have the appropriate air compressors with the correct volume and pressure to safely remove all the water from your system. By relying on professionals, you can have peace of mind knowing that your sprinkler system is properly winterized and protected from winter-related damage.

Steps to Blow Out Your Sprinkler System
To ensure your sprinkler system is winter-ready, follow these steps to effectively blow out your system and remove all water from the pipes.
- Shut off the main water supply: Locate the main valve that controls the water flow to your sprinkler system and turn it off. This will prevent any water from entering the system during the blow out process.
- Drain the remaining water: To remove any remaining water from the pipes, open all the drain valves and drain any underground pipes by loosening the drain caps. Make sure all the water has been drained completely.
- Attach an air compressor: Connect the air compressor to the system using a blow out adapter. The blow out adapter acts as a connection between the compressor and your sprinkler system.
- Set the air compressor: Ensure that your air compressor provides a volume of at least 30-50 cubic feet per minute (cfm) and blows pressure at 40-80 pounds per square inch (PSI). Adjust the pressure regulator on the compressor accordingly.
- Blow out the sprinklers: Begin blowing out the sprinklers starting with the farthest zone from the mainline. Gradually increase the pressure to the recommended PSI for your system. This will help prevent damage to the pipes. As the water spray stops, close each sprinkler head or zone.
- Close the valves: Once you have blown out all the sprinklers, close the shut-off valve on the compressor. Then, open and close the backflow device valves to release any pent-up air pressure.
Insulate the above-ground fixtures of your irrigation system to prevent freezing. Use insulation tape or covers to protect exposed pipes, valves, and connectors. This will help ensure that your system remains in good condition throughout the winter.
Remember: Safety First
When performing a blow out, always keep safety in mind. Wear safety goggles and ear protection when operating the air compressor. Be cautious of any flying debris that can be propelled by the high-pressure air. If you are unsure about any step of the process, it is best to seek professional help to avoid any potential damage to your sprinkler system.
Table: Recommended PSI for Sprinkler Systems
| Type of Sprinkler System | Recommended PSI |
|---|---|
| Rotating Sprinklers | 40-50 PSI |
| Mist Sprayers | 30-40 PSI |
| Pop-up Sprinklers | 30-40 PSI |
By following these steps and properly blowing out your sprinkler system, you can ensure that your irrigation system is protected from the potential damage caused by frozen water during the winter months. Taking the time to winterize your system now will save you time and money on repairs in the future.
Choosing the Right Air Compressor and Pressure
Selecting the right air compressor and pressure settings is crucial for effectively blowing out your sprinkler system and preventing potential damage. The blow out method relies on high pressure air to force out all the water from the system, ensuring no water remains to freeze and cause costly repairs. When it comes to choosing the right air compressor, there are a few key factors to consider.
First and foremost, the air compressor should have a volume of at least 30-50 cubic feet per minute (cfm) to provide sufficient airflow. This volume allows for the quick and complete removal of water from the pipes and sprinkler heads. Without the right volume, the blowing out process may not be effective, leaving water trapped in the system.
In addition to volume, it’s crucial to pay attention to the pressure the air compressor can produce. The recommended pressure range for blowing out a sprinkler system is between 40-80 pounds per square inch (PSI). This range ensures that enough force is applied to expel the water while avoiding excessive pressure that could damage the system.
| Air Compressor Requirement | Volume (cfm) | Pressure (PSI) |
|---|---|---|
| Minimum Requirement | 30-50 | 40-80 |
| Recommended | 50-80 | 50-70 |
Once you have selected the appropriate air compressor, it’s time to set the pressure. Start with the lowest pressure within the recommended range and gradually increase if necessary. It’s crucial to monitor the system while blowing out to ensure optimal results without causing any damage.
By choosing the right air compressor with the correct volume and pressure settings, you can confidently blow out your sprinkler system, safeguarding it against winter freeze damage. Remember to follow the recommended PSI range and take the necessary precautions to protect your above-ground fixtures. With proper winterization, your sprinkler system will be ready to withstand the harsh winter conditions and perform optimally in the spring.
Additional Winterization Tips
In addition to blowing out your sprinkler system, there are a few extra steps you can take to ensure proper winterization and protect your system from potential freezing and damage.
1. Insulate above-ground fixtures:
One of the key areas vulnerable to freezing is the above-ground fixtures of your irrigation system, such as backflow preventers and valves. Insulating them with foam insulation or heat tape can help protect them from freezing temperatures.
2. Close the shut-off valve and backflow device valves:
After blowing out your system, make sure to close the shut-off valve on the air compressor. Additionally, open and close the valves on your backflow device to release any remaining air pressure. This will prevent any potential damage from a build-up of air pressure during the winter months.
3. Remove any sediment or debris:
Prior to winterizing your sprinkler system, it’s important to remove any sediment or debris that may have accumulated in the pipes throughout the season. This can be done by flushing the system with water before blowing it out. This step will help prevent clogs and blockages that could hinder the blow out process.
4. Schedule professional winterization:
If you’re unsure about the winterization process or simply prefer to leave it to the experts, consider hiring a professional sprinkler winterization service. They have the knowledge, experience, and specialized equipment to ensure your system is properly prepared for the winter months.
By following these additional winterization tips, you can protect your sprinkler system from potential freezing and damage, ensuring it remains in optimal condition for the next growing season.
