If you live in a cold climate, you know the dangers of frozen pipes. Water left inside irrigation lines, sprinkler systems, or plumbing can expand when it freezes, leading to burst pipes and expensive repairs. The most reliable way to prevent this is by blowing out water pipes with an air compressor. This process forces remaining water out of the system, leaving it dry and safe for winter.
But here’s the catch: not all air compressors are powerful enough for the job. Choosing the right compressor ensures you can blow out pipes safely and efficiently without damaging fittings. In this guide, we’ll explain how to blow out pipes, what to look for in a compressor, and which models are the best for both homeowners and professionals.
Quick Picks: Best Air Compressors for Blowing Out Water Pipes
- Best Overall: Quincy QT-54 Reciprocating Air Compressor – Strong, durable, and ideal for sprinkler systems.
- Best Budget: Ingersoll Rand 2340L5-V Two-Stage Compressor – Affordable heavy-duty choice for home and light commercial use.
- Best Premium: Atlas Copco GA Series Rotary Screw Compressor – Professional-grade system for contractors blowing out large properties.
Buyer’s Guide: Choosing the Right Compressor
When selecting an air compressor for blowing out water pipes, consider these key factors:
- CFM Output: Sprinkler systems and irrigation lines often require 10–20 SCFM at 50–80 PSI. Large systems may need 30+ SCFM.
- Tank Size: A larger tank (60–80 gallons) provides steady airflow without frequent cycling.
- PSI Rating: Most residential systems don’t need more than 80 PSI. Avoid exceeding recommended pressures to prevent damage.
- Portability: Contractors may prefer tow-behind or portable compressors, while homeowners benefit from stationary shop units.
- Durability: Cast iron pumps and industrial-grade parts ensure long life under seasonal workloads.
⚠️ Important Safety Tip: Never exceed the recommended PSI for your plumbing or sprinkler system—too much pressure can blow out fittings instead of water.

FAQ
What PSI should I use to blow out sprinkler lines?
Most systems recommend 40–80 PSI. Exceeding this can damage fittings or sprinkler heads.
Can I use a small pancake compressor?
No. Pancake and portable compressors don’t provide enough CFM for a proper blowout. A 60+ gallon unit is recommended.
How often should I blow out water pipes?
At least once before the first freeze each year, and after fall irrigation use if temperatures drop.
Is it better to hire a professional?
For small systems, DIY blowouts are simple. For large irrigation networks, contractors with high-CFM compressors save time and ensure complete protection.
Will blowing out pipes damage them?
Not if you use the right PSI. The goal is to remove water—not stress the plumbing.
Conclusion
Blowing out water pipes before winter is one of the smartest ways to avoid costly freeze damage. With the right compressor, the process is simple, safe, and effective. For most homeowners, the Quincy QT-54 or Ingersoll Rand 2340L5-V provide more than enough airflow.
