How to Winterize Your Sprinkler System (and why it matters)
When cold weather hits Tulsa and Broken Arrow, one of the smartest things you can do for your lawn is winterize your sprinkler system. Skipping this step might not seem like a big deal, but one hard freeze can cause pipes to crack, valves to burst, and repairs to pile up fast.
Here’s what irrigation winterization is, why it matters, and what to expect from the process.
What Is Irrigation Winterization?
Winterization (or a “sprinkler blowout”) is the process of clearing water from your irrigation system before freezing temperatures arrive. Even a small amount of water left in the pipes can expand when it freezes, leading to leaks or broken fittings.
A professional irrigation technician will:
Shut off the water supply to your sprinkler system.
Use an air compressor to blow any remaining water out of pipes, valves, and sprinkler heads.
Inspect the system for leaks or damage before it’s shut down.
Set the controller to “off” or “rain mode” so it doesn’t activate during winter.
When done correctly, your system stays safe, dry, and ready to go when spring returns.
Why It’s Important in Oklahoma
In Tulsa and Broken Arrow, temperatures can swing quickly from warm to below freezing overnight. That means even one unexpected cold snap can cause thousands of dollars in damage if water is trapped in the lines.
Winterizing your sprinkler system helps you:
Avoid costly repairs to cracked pipes and valves.
Extend your system’s lifespan, keeping it running efficiently.
Save water and energy by avoiding leaks or broken sprinkler heads.
Enjoy peace of mind knowing your system is protected until spring.
When Should You Winterize?
The best time to schedule your irrigation winterization is late October through early November, before the first hard freeze. Every year is a little different, but it’s best not to wait. Once temperatures drop into the 20s, it may already be too late to prevent damage.

Why Hire a Professional
While DIY blowouts might seem simple, they can actually cause more harm than good if done incorrectly. Too much air pressure can damage sprinkler heads, while too little leaves water behind.
