Irrigation System Shutdown: How to Properly Winterize to Prevent Damage
A checklist for commercial property managers to safeguard systems
As temperatures drop across the Philadelphia region, commercial property managers have one critical task before winter hits: properly shutting down and winterizing the irrigation system. Neglecting this step can lead to cracked pipes, costly repairs, and water damage come spring.
At C. Caramanico & Sons, Inc., we help property managers protect their landscapes year-round—and a professional irrigation system shutdown is a key part of that protection plan.
💧 Why Irrigation Winterization Matters
When water remains in pipes and components during freezing weather, it expands as it turns to ice. This can cause:
- Burst pipes and fittings
- Damaged valves and backflow preventers
- Costly spring repairs and downtime
- Delayed start-up next season
A professional winterization service ensures your system is cleared, sealed, and safe until temperatures rise again.
✅ Commercial Irrigation Winterization Checklist
Here’s a step-by-step guide to properly shutting down your irrigation system before winter:
1. Schedule Early
Don’t wait for the first freeze. Schedule your shutdown in October or early November to ensure your system is ready before the cold sets in.
2. Turn Off the Water Supply
Locate and shut off the main irrigation water line to prevent new water from entering the system.
3. Drain or Blow Out the System
Using professional-grade air compressors, irrigation technicians blow out all remaining water from lines, valves, and sprinkler heads. This is one of the most important steps in preventing freeze damage.
4. Protect the Backflow Preventer
Your backflow device is especially vulnerable to freezing. It should be:
- Properly drained
- Insulated or covered with a weatherproof wrap
- Tagged and documented for compliance
5. Shut Down the Controller
Switch your irrigation controller to “off” or “rain mode” to stop automatic cycles. For smart systems, disable scheduling but keep power on to retain programming data.
6. Inspect for Wear or Damage
While the system is off, it’s the perfect time to inspect sprinkler heads, valves, and wiring for wear. Making repairs now prevents surprises in spring.
7. Document & Plan Ahead
Keep a record of the service date, technician notes, and any recommended improvements. A winterization report helps you plan maintenance or upgrades for the next season.
