Sprinkler Blowout & Startup Services

Your irrigation system is a significant investment in your property. In Idaho’s climate, where winter temperatures regularly drop well below freezing, proper winterization isn’t optional—it’s essential.

Fall Sprinkler Blowout

When water freezes, it expands. Water left in your sprinkler lines, valves, and heads can cause:

  • Cracked pipes requiring excavation to repair
  • Broken valves that cost hundreds to replace
  • Damaged heads that spray erratically or not at all
  • Manifold failures that can flood your yard

Our professional blowout service uses high-volume compressed air to push every drop of water out of your system, ensuring nothing is left to freeze.

What’s Included

  • Complete water removal from all zones
  • Proper air pressure calibrated for your system type
  • Backflow preventer protection
  • Controller shutdown and winterization
  • Visual inspection for potential issues

Spring Startup

When the danger of frost has passed, we return to bring your system back to life:

  • Controller programming for the current season
  • Zone-by-zone testing to identify problems
  • Head adjustment for optimal coverage
  • Leak detection at all connections
  • Coverage optimization to eliminate dry spots
