AZ Irrigation & Maintenance winterizes sprinkler and drip systems in Flagstaff, Sedona and the Verde Valley. Our Irrigation Association certified technicians shut off the water, drain and protect the backflow assembly, and blow out every zone with compressed air before the first hard freeze. One-time service is $165 for the first hour, and AIMazing members pay $135.
Freezing temperatures can cause serious damage to irrigation systems if they aren’t properly shut down. We help Northern Arizona homeowners safely winterize their sprinkler and drip systems to prevent freeze damage, protect equipment, and avoid costly repairs in the spring. We make irrigation simple — diagnose clearly, fix correctly, maintain proactively.
Many systems are damaged each year because winterization is done incorrectly or skipped entirely.
Common risks include:
Proper winterization protects your system and reduces surprises when irrigation season returns.
At AZ Irrigation & Maintenance, irrigation is our specialty — not just one of many services. Our licensed, insured, and Irrigation Association–certified professionals understand the specific freeze risks and seasonal conditions unique to Northern Arizona. We follow structured winterization procedures designed to protect your system long-term.
1. System Evaluation
We inspect your irrigation system and prepare it for shutdown.
2. Professional Blowout & Shutdown
We use proper compressed-air techniques to remove water from irrigation lines and protect components from freezing.
3. Spring Readiness (Optional)
Join our AIMazing Irrigation Package and we’ll automatically schedule seasonal services so your system is protected year after year.
No guessing, no pressure — just reliable irrigation that works.
The goal is simple: protect your system through winter and avoid costly freeze damage.
Your backflow preventer is one of the most vulnerable components of your irrigation system in freezing weather. To avoid costly damage, it’s essential that the backflow device is properly insulated.
If you don’t already have one, we can supply a cover at an additional cost. Or you can follow the steps shown in our backflow protection video guide (available on our website) to prepare your device in advance.
We’re happy to inspect your backflow setup and confirm that it’s protected during our winterization service.
Even after your system has been winterized, we recommend periodically checking your stop-and-waste valve throughout the winter. These valves typically last 10–20 years and may fail with age.
We’ll show you how to inspect your valve and determine if it’s in good condition. If replacement is needed, we’ll provide recommendations and repair options.
It’s always better to complete sprinkler system winterization early and avoid unnecessary risk.
After diagnosing your system, our technicians present structured repair and improvement options:
Critical Repairs — Issues that should be addressed now to prevent damage, system failure, or water loss
Recommended Improvements — Enhancements that improve efficiency, performance, or long-term reliability
We explain what’s necessary, what’s recommended, and what can wait — before any work is performed.
