Irrigation systems left with water in the lines will crack when temperatures drop below freezing—common by mid-to-late October on the Western Slope. Professional blow-out using compressed air removes water from pipes, valves, and heads.

Do not rely on simply shutting off the water. Residual water in low spots or valves can still freeze and cause expensive spring repairs. Schedule the blow-out before the first hard freeze.

If you have a backflow preventer, protect it according to manufacturer recommendations or have it winterized as part of the service.

Cooley’s Heating, Cooling & Plumbing provides irrigation winterization for properties in Delta, Montrose, and Mesa counties. Book early to avoid the rush.

Key Takeaways

• Professional blow-out is the reliable method.
• Schedule before mid-October hard freezes.
• Protect backflow devices as well.
