Sprinkler Winterization
Protect The System Before Freezing Nights
St. George winters are mild, but Washington County still sees freezing nights — and water left sitting in exposed pipes, valves and backflow devices can freeze, expand and crack components. Winterization prepares the system for those nights; spring start-up brings it back into service and checks what winter left behind.
These are the two bookends of the watering year, and they work as a pair. Our family-owned team shuts systems down in fall with the components that need protection, then returns in spring to restore service, review coverage and set the controller for the season ahead.
What’s Included
The Main Parts Of Your Project
Fall Shut-Down
Close the water supply to the irrigation system and prepare the components that hold water. The shut-down scope depends on how your system is built and which parts are exposed.
Draining The System
Drain lines, valves and devices within the agreed scope so standing water cannot freeze and expand. Exposed and above-ground components deserve the most attention.
Spring Start-Up
Restore the water supply, pressurize the system and run each zone to confirm operation. Start-up is the natural moment to spot damage that developed over winter.
Seasonal Controller Review
Set the controller for the coming season at start-up and review it at shut-down. A system that hibernates with the right settings restarts with fewer surprises.
The Process
From First Conversation To Installation
- 01
Book Before The Freeze
Call in fall before freezing nights arrive. Tell us the property location and system size so we can plan the shut-down visit.
- 02
Shut Down & Drain
Complete the agreed winterization: supply shut-off, draining and protection of exposed components.
- 03
Start Up In Spring
Restore service when the watering season approaches, pressurize the system and run each zone.
- 04
Review & Set
Check coverage, note anything needing repair and set the controller for the season. Repair work beyond the start-up is scoped separately.

Project Considerations
The Backflow Device Deserves Special Attention
The backflow prevention device is often the most exposed and most expensive component to freeze. It typically sits above ground where cold air reaches it first, and a cracked device can mean replacement rather than a simple fix.
Winterization should always account for it. If you are not sure what device your property has or where it sits, mention it when you call — our backflow prevention page explains what these devices do and how we approach their installation and repair.

Local Considerations
Winterization In Washington County
Freezing Nights Happen Here
St. George is not a hard-freeze climate, but clear winter nights regularly drop below freezing — especially in Ivins, Santa Clara and higher-elevation areas. One cold snap is enough to crack an unprotected component.
Exposed Components First
Above-ground valves, devices and exposed piping face the most risk. Buried lines are somewhat protected by soil, which is why the shut-down scope focuses on what the cold can actually reach.
Timing The Seasons
Shut-down timing depends on when you stop watering; start-up depends on when the landscape needs water again. We schedule around your property rather than a fixed calendar date.
