Irrigation Winterization

FREE QUOTE

Protect Your Irrigation System from Freeze Damage.

Winterizing your irrigation system is an essential step in protecting it during the colder months. Water left inside pipes, sprinkler heads, valves, and backflow devices can freeze and expand, causing cracks and costly damage. Even when your sprinklers are turned off, trapped water can remain in the system. Proper winterization helps reduce that risk before freezing temperatures arrive.

Professional winterization protects your investment, helps extend the life of your irrigation equipment, and reduces the chance of unexpected repairs when watering season returns. It also helps prevent leaks and wasted water caused by freeze damage. For homeowners throughout Middle Tennessee, annual winterization is an important part of keeping an irrigation system reliable year after year.

At A&S Outdoors, our winterization process includes shutting off the irrigation water supply, removing remaining water using the appropriate method for your system, and preparing the controller for winter. When a blowout is needed, we use controlled compressed air to clear the irrigation zones while respecting the equipment’s pressure limits. We also address the backflow device and exposed components according to their winterization requirements, helping prepare your system for cold weather and a spring startup.

Frequently Asked Questions

1. When should I schedule irrigation winterization?

Schedule your service in the fall, before the first hard freeze. Booking early helps ensure your system is prepared before freezing weather arrives.

2. Do I need winterization if I’ve already turned off my sprinklers?

Yes. Turning off the controller stops scheduled watering, but it does not remove water trapped inside pipes, valves, sprinkler heads, or the backflow device.

3. What happens if I don’t winterize my irrigation system?

Remaining water can freeze and expand, damaging irrigation components. Some damage may not become apparent until the system is turned back on in spring, when leaks or malfunctioning zones appear.

4. Does drip irrigation need to be winterized, too?

Yes. Drip systems can retain water in tubing, valves, filters, and pressure regulators. These components need to be prepared for winter using methods appropriate for the equipment.

5. Can I winterize the system myself?

Winterization requires knowing how your system drains and how each component should be handled. Incorrect air pressure or blowout procedures can damage equipment. Professional service helps ensure the proper method is used for your system.

6. When should my irrigation system be turned back on?

Schedule a spring startup once the risk of damaging freezes has passed and your landscape needs regular watering. A startup visit allows the system to be checked for leaks, proper sprinkler operation, and appropriate controller settings.
The technical guidance follows Rain Bird and Hunter winterization recommendations.
