Irrigation Winterization

Irrigation Winterization

Protect sprinkler systems from Raleigh's freeze-thaw cycles

While our winters are mild, sudden temperature drops can burst pipes in un-winterized systems. We use industrial air compressors to blow out all water, focusing on vulnerable backflow preventers common in Morrisville's newer installations.

The ideal time for winterization is mid-October through November, after the last mowing but before consistent freezing begins. We tag each zone as it's completed and provide digital documentation of the service.

For historic homes Inside the Beltline with older galvanized pipes, we recommend additional insulation. Our technicians are trained to identify early corrosion that could lead to spring leaks.

Our Process

  1. 01 Step 1: Shut off and drain main water supply
  2. 02 Step 2: Connect compressor to blow out each zone
  3. 03 Step 3: Manual drain of low-point valves
  4. 04 Step 4: Insulate above-ground components

Benefits

  • Prevents costly pipe repairs come spring
  • Identifies worn valves needing replacement
  • Extends system lifespan by 3-5 years
  • Includes free spring startup inspection

Frequently Asked Questions

Do I need this if we rarely freeze?

Yes. Even one night below 25°F can damage systems. The 2022 Christmas freeze caused $200,000+ in local irrigation repairs.

Can I winterize my own system?

DIY attempts often leave water in lateral lines. Our 100 CFM compressors remove 98% more moisture than consumer models.
