Fall Winterization
& Sprinkler Blowouts
Protect your irrigation system from brutal Montana freeze damage with high-CFM commercial air compressors.
Don't let sub-zero weather ruin your mainline.
When ground temperatures plunge in Gallatin County, water left inside PVC or poly pipes freezes and expands with tremendous force, shattering valves and fracturing mainlines underground.
Lawn Rain uses high CFM (Cubic Feet per Minute) tow-behind air compressors. By prioritizing high air volume over dangerous high PSI, we clear every drop of standing water from heads and backflows without melting or damaging internal components.
Commercial Air Compressors
Full-volume evacuation for every zone
The Blowout Process
Main Shut-off Isolation
Securing the primary water source and pressure vacuum breaker assemblies.
High-CFM Air Hookup
Connecting commercial air regulated precisely to safe 50-60 PSI parameters.
Multi-Cycle Zone Clearing
Cycling every valve multiple times until only fine vapor spray exits the heads.
Backflow Assembly Drainage
Draining test cocks and ball valves on the backflow device to prevent $500+ replacements.
Controller Winterization
Setting timers to rain delay or standby mode to preserve memory settings.
Freeze Protection Warranty
Guaranteed protection against freeze breaks when serviced before October deadline.
