Irrigation Start-Ups

Professional Irrigation Start-Up Services in Woodbury, Rosemount & Stillwater, MN, and Hudson, WI

Get your sprinkler system ready for the growing season with expert spring activation and system testing

When Minnesota and Wisconsin lawns begin emerging from winter dormancy, your irrigation system needs professional attention to deliver reliable watering all season long. LNG Landscapes provides comprehensive irrigation start-up services that safely restore your system to full operation while identifying potential issues before they become costly repairs.

Our technicians follow a meticulous process to bring your system back online, from pressurizing lines and testing zones to programming controllers and verifying rain sensors. Every start-up includes thorough inspection of sprinkler heads, valves, and backflow preventers to ensure optimal performance throughout the growing season.

Our Spring Irrigation Start-Up Process

LNG’s irrigation start-up service runs from April through May, timed perfectly with Minnesota and Wisconsin’s transition out of winter. Our systematic approach ensures your system operates efficiently from day one:

System Pressurization & Testing
We begin by closing all drain valves at sprinkler heads and underground valve boxes, then carefully prepare your backflow preventer for operation. The main water line is turned on gradually, followed by controlled pressurization of the backflow preventer to prevent water surges that can damage pipes and components.

Zone-by-Zone Inspection
Each irrigation zone runs for 2-3 minutes while our technicians check for proper coverage, head alignment, and water pressure. We inspect every sprinkler head for clogs, damage, or misalignment that occurred during winter, making adjustments to ensure even water distribution across your lawn and landscape beds.

Controller Programming & Rain Sensor Testing
Your irrigation controller receives fresh programming based on current weather patterns and seasonal watering needs. We thoroughly test rain sensors to confirm they’ll prevent unnecessary watering during spring storms, protecting both your landscape and water bill.

Why Professional Start-Up Matters

Minnesota and Wisconsin winters are tough on irrigation systems. Even properly winterized systems can develop issues during months of inactivity. Common problems our technicians discover during start-ups include broken or clogged sprinkler heads, leaking zone valves, frozen or burst pipes, misaligned heads, and controller malfunctions.

Attempting DIY start-up risks serious damage from improper pressurization or overlooked leaks. Our trained technicians know exactly how to safely restore water flow while catching problems early. We use systematic testing procedures that prevent costly mistakes and ensure your system delivers consistent, efficient watering.

Backflow Testing & Compliance

Every LNG start-up includes professional backflow testing to protect your home’s water supply from contamination. This annual testing is mandatory in most municipalities and ensures your irrigation system’s backflow preventer functions properly.

Our technicians thoroughly inspect and test the backflow prevention device, checking connections and protective coverings while documenting results for municipal compliance.

For commercial properties, we provide backflow testing year-round as part of our comprehensive irrigation services. Residential testing occurs when temperatures allow safe operation of testing equipment.
