It’s important to ensure that your underground sprinkler system is well-maintained and protected from the elements. It’s not as simple as turning off the water — it’s imperative that you have your home’s irrigation system winterized by a professional each year so you don’t risk a major sprinkler system repair issue.

Winterize your system properly with professional service.

What Can Happen If You Don’t Winterize Your Irrigation System?

Improperly winterized irrigation systems can create issues far bigger than busted sprinkler heads — underground pipes can freeze, leading to much bigger and more costly repairs. Ontario’s winter temperatures regularly drop well below zero. Shutting down your irrigation system in the winter is critical, as freezing temperatures below -15ºC creates a risk of burst pipes. If a system is shut down incorrectly, a sprinkler system will still contain water, even if the water supply is turned off at the control valve.

How To Winterize Your Sprinkler System

We don’t recommend trying to winterize your sprinkler system on your own. Due to the risk of underground pipe bursts, it’s highly recommended that you have this process performed by a professional each year.

Turning Off The Control Valves

Your irrigation system is more complicated than it looks. One of the most common mistakes homeowners make when trying to winterize their own sprinkler systems is to incorrectly turn off the valves and shut off the water. Valves make your sprinkler system work well in the summer, but if your system isn’t properly winterized by a professional, they could be the reason why you need a repair in the spring.

Proper Drainage Of Your Irrigation System

In order to properly winterize your system, it’s imperative that you drain the water correctly. Your system is equipped with a backflow device that prevents water from draining back into your water supply, but it can also make it tricky for your system to drain properly. Backflow preventers require manual draining to remove the remaining water, so it’s not as simple as shutting off the water and using an automatic drain method.

Blowing Out The System With Compressed Air

In order to remove the remaining water after drainage, a fully-winterized system should be blown out with compressed air. This will ensure that no water will remain in the spray heads or underground pipes. A proper air compressor is necessary, but the method is equally important. While you need to open backflow preventers to drain the system, it’s important to close them again in order to make sure that no compressed air is blown through them.

Call The Professionals

It’s common for homeowners to attempt to winterize their irrigation systems themselves, only to call us in the spring when their system isn’t working properly. It’s a job best performed by experienced professionals.

At Arizona Outdoor Solutions, we include winterization as part of our comprehensive year-round maintenance packages. We’ll take care of everything before the first freeze, which is critical in places like Ontario, where the frost depth reaches below the depth of installed piping. You can relax knowing that your system has been maintained properly by qualified professionals and will continue working year after year.

This year I decided to hire Arizona Outdoor Solutions…I’ve dealt with several other companies over the last 13 years that all ended in disappointment, so I was seeking a reliable, honest and friendly company to oversee our sprinkler system needs. After reading their reviews and calling their office to enquire about service, I was impressed!I felt it was important to familiarize them with our older system, and I’ve found both technicians that I’ve met to be very patient, professional, helpful and efficient. The office is prompt in their responses and the ‘tracking’ of appointments, services required and services completed is very detailed which makes it easy to reference when needed. I feel like I’ve finally found a company that I can trust to do what needs to be done. They are all about customer satisfaction! Definitely very satisfied with their service and look forward to annual service!

We are seniors and had realized that an irrigation system is becoming a positive for most people looking to buy a house in our area. We talked to a few installers but Rick patientlytook the time to describe the benefits, costs and process involved. It didn't feel like selling the product was the main aim but that he really cared about all that this summer had taken out of us and knew this would make such an improvement in the quality of the lawn during the season. Hauling the hose around to water this summer was getting more and more difficult and it didn't seem to help the lawn flourish at all! The installation went smoothly and Rick took the time to walk me through my technological hurdles until he was sure that I understood and could use the convenient app. Now I can see which zones are watering, the weekly programs, and water savings, all while knowing that the company is there when I might need them.

Rick of Arizona Irrigation installed our irrigation system well over 10 years ago, and was courteous and professional. The system has run flawlessly from day one! From spring startup to fall shutdown, their technicians show up promptly as scheduled, and are pleasant, efficient and thorough, using only top quality parts.The result is a system that runs efficiently with minimum water use, and keeps our lawn and gardens looking healthy and beautiful, no matter how hot and dry the season is! Well worth the investment.

Having Arizona Irrigation and Outdoor Solutions install our irrigation system was a very smooth and painless experience. The crew was amazing – they worked quickly and efficiently and answered all of the many questions I had about the installation and how to operate the system.

We hired Arizona Irrigation to install our irrigation system over ~6000sf of lawn space. Rick and his crew were awesome, and the final product works flawlessly. The system was installed right before we laid new sod. Initially, I had an issue with a couple of the zones and controller. Rick came out that day to inspect the system, correct the issues, and make some adjustments to the setup -- right in time to ensure the fresh sod got the water it needed.Four weeks later, everything is still operating as expected with no issue -- and the yard looks great! Highly recommend Rick and the Arizona crew for future irrigation needs.

I have been working with Arizona for approx 3 years. They revived an unused front yard sprinkler system, plus we have worked on adding a back yard sprinkler system, and upgrading to a modern digital control box, and now rain sensor. They are well trusted for our system openings and closings. Rick and the team have been good to deal with, offering ideas and advice, and delivering timely, quality installation and service. Thanks Arizona!
