Irrigation sprinkler shutoff

---

As temperatures drop, it’s critical to properly shut down your irrigation system before freezing weather arrives.

Water left in your sprinkler lines can freeze, expand, and crack pipes, valves, and sprinkler heads. This can lead to:

• Costly repairs in the spring 
• Underground leaks you may not notice right away 
• Damage to your backflow preventer and main water line 

A proper winterization protects your entire system and saves you money long-term.

Winterizing an irrigation system involves:

• Turning off the water supply to the system 
• Draining all remaining water from pipes and valves 
• Using compressed air to “blow out” any leftover water (the most important step) 
• Shutting down and securing the backflow preventer 

While it may seem simple, irrigation blowouts require specialized equipment and experience. Using the wrong air pressure or method can:

• Damage pipes or fittings 
• Ruin sprinkler heads 
• Void equipment warranties 

A professional ensures:

• The system is fully cleared of water 
• Proper pressure is used 
• All components are safely shut down
