Sprinkler Winterization: When & How to Winterize Your System
Sprinkler winterization is the process of removing water from an irrigation system before freezing temperatures arrive. Proper winterization helps protect underground pipes, valves, sprinkler heads, and other components from freeze-related damage.
For homeowners in Sioux Falls, Des Moines, and other Midwest communities, properly winterizing a sprinkler system should be an important part of seasonal sprinkler system maintenance.
Why Does Irrigation Winterization Matter?
Water expands when it freezes. If water remains trapped inside an irrigation system as temperatures drop below freezing, the expansion can place pressure on pipes, fittings, valves, and other components.
That damage may not become apparent until spring, when you turn the system back on.
Weller Brothers recommends winterizing irrigation systems before freezing temperatures arrive and uses the blow-out method to remove excess water from irrigation lines.
When Should You Winterize Your Sprinkler System?
There isn’t one exact calendar date that works for every property. Winterization should be scheduled based on local weather conditions and the likelihood of sustained freezing temperatures.
In the Midwest, that generally means planning irrigation winterization in the fall before the ground and irrigation components are exposed to prolonged freezing conditions.
Waiting until the first major freeze can increase the risk of damage and may also make scheduling more difficult during the busiest part of the season.
How is a Sprinkler System Winterized?
There are several methods for removing water from an irrigation system, including manual draining, automatic draining, and compressed-air blowouts.
The blow-out method uses compressed air to force remaining water out through the sprinkler heads. However, using excessive air pressure or improperly connecting equipment can damage an irrigation system and create safety hazards.
For that reason, homeowners who are unfamiliar with irrigation systems may benefit from having winterization performed by an experienced professional.
Don’t Forget About Your Backflow Device
The irrigation system isn’t the only component that needs attention before winter. Depending on the system, water may remain in the area between the irrigation shutoff and the backflow prevention device.
These components should be handled carefully during the winterization process.
