The winter weather conditions found in the Flagstaff area of Northern Arizona are very attractive, yet harsh. Rather quickly, freezing temperatures could turn a sound investment, such as your automatic sprinkler system, into a financial disaster if not properly winterized.
As a specialist company, AZ Irrigation & Maintenance (AIM), we are aware of the unique risks associated with the freezes of the Arizona climate to underground irrigation. Irrigation winterization blowout is more than a recommendation—a necessary service when it comes to preparing your irrigation system for spring.
Although the primary turnoff valve is turned off, the force of gravity will drain a portion of the water supply. With the depths of most residential irrigation systems being relatively shallow, the remaining water is extremely vulnerable to freezing.
As it freezes, water expands, which creates a lot of pressure. The expansion could potentially rupture the following important components:
The Bottom Line: basic freeze can mean thousands of dollars in sprinkler system repair costs. These costs are apparent at the time when the water is most in demand.
Effective winterization will require specialized, high-volume air compressors, which push each remaining drop of water out of the pipeline and beyond, without actually forcing any more water into the pipeline. Our certified AIM technicians follow a specific procedure to safeguard against freezing:
In Flagstaff, the window for winterizing is critical. Although the end of the irrigation season could vary, it is important to arrange service before the first hard freeze, which could occur starting either in October or November..
