Save Time and Money: DIY Sprinkler System Blow Out with Air Compressor Explained
What To Know
- One of the most effective ways to do this is to blow out the system with an air compressor.
- Connect the air hose to the air compressor and the other end to the blowout plug.
- The blowout plug is usually a small brass fitting located at the lowest point of the sprinkler system.
As the chilly winter months approach, it’s crucial to winterize your sprinkler system to prevent damage from freezing temperatures. One of the most effective ways to do this is to blow out the system with an air compressor. This process removes water from the pipes and sprinkler heads, ensuring they remain intact during the cold season.
Materials You’ll Need
- Air compressor (at least 30 PSI)
- Air hose (at least 10 feet long)
- Blowout plug
- Safety glasses
- Gloves
Step-by-Step Instructions
1. Shut Off Water Supply
Begin by turning off the water supply to the sprinkler system at the main valve. This is typically located near the water meter.
2. Open Sprinkler Heads
Open all the sprinkler heads on the system to allow water to drain out. This will help prevent water from freezing inside the heads.
3. Connect Air Compressor
Connect the air hose to the air compressor and the other end to the blowout plug. The blowout plug is usually a small brass fitting located at the lowest point of the sprinkler system.
4. Insert Blowout Plug
Insert the blowout plug into the designated port on the sprinkler system. Make sure it is securely fastened to prevent air leaks.
5. Start Air Compressor
Turn on the air compressor and adjust the pressure to around 30 PSI. This pressure is sufficient to blow out the water without damaging the pipes.
6. Blow Out Water
Slowly open the valve on the blowout plug to allow pressurized air to flow into the system. Gradually increase the airflow until water starts to discharge from the sprinkler heads.
7. Continue Blowing
Continue blowing air through the system until all the water has been expelled. This may take several minutes. If you encounter any areas where water is still trapped, use a small brush or wire to clear the obstruction.
8. Disconnect Air Compressor
Once all the water has been blown out, turn off the air compressor and disconnect the air hose. Remove the blowout plug and store it in a safe place.
9. Close Sprinkler Heads
Close all the sprinkler heads to prevent any remaining water from freezing.
Safety Precautions
- Wear safety glasses and gloves when working with an air compressor.
- Never exceed the recommended pressure for your sprinkler system.
- Keep the air compressor away from flammable materials.
- Do not blow out the system if the temperature is below freezing.
Benefits of Blowing Out Sprinkler Systems
- Prevents freezing and damage to pipes and sprinkler heads
- Extends the lifespan of the sprinkler system
- Reduces the risk of leaks and costly repairs
- Ensures the system is ready for use when spring arrives
Conclusion
Blowing out your sprinkler system with an air compressor is a relatively easy and inexpensive way to prepare it for winter. By following these steps and taking necessary safety precautions, you can ensure your system remains in good condition during the cold months.
FAQ
Q: Can I use any air compressor to blow out my sprinkler system?
A: No, you should use an air compressor with a pressure of at least 30 PSI.
Q: How long does it take to blow out a sprinkler system?
A: The time it takes depends on the size and complexity of the system. Typically, it takes around 15-30 minutes.
Q: What should I do if I encounter any frozen water in the sprinkler heads?
A: Use a small brush or wire to gently remove the ice. Do not apply excessive force as it may damage the sprinkler head.
