Sprinkler System Spring Startup in Chicago & the North Shore

Get Your Irrigation System Ready for the Growing Season

After a long Illinois winter, your sprinkler system needs a careful, professional startup to ensure everything is working properly before you rely on it to keep your lawn green. American National Sprinkler & Lighting provides comprehensive spring activation services that go far beyond simply turning the water back on.

Our spring startup service identifies any winter damage, calibrates your system for optimal performance, and ensures every zone is delivering the right amount of water to the right places. Starting your system incorrectly can cause water hammer, pipe damage, or flooding — our technicians know exactly how to bring your system online safely.

What Our Spring Startup Service Includes

Gradual System Pressurization

We slowly open the main water supply to your irrigation system, allowing pressure to build gradually. This prevents water hammer — a dangerous pressure surge that can crack pipes, damage valves, and blow sprinkler heads off their risers.

Backflow Preventer Inspection

We inspect your backflow prevention device for any winter damage, test its operation, and verify it is functioning properly before the system goes live. Illinois requires annual backflow testing, and we can handle that at the same time.

Head-by-Head Inspection

Our technicians activate each zone individually and inspect every sprinkler head for proper operation. We check for heads that are stuck, broken, tilted, or blocked by grass growth. Misaligned heads waste water and leave dry spots in your lawn.

Controller Programming

We review and update your irrigation controller programming for the spring season. This includes setting appropriate run times, start times, and watering days based on current weather patterns and your landscape needs. For smart controllers like Hunter Hydrawise and Rainbird, we verify the Wi-Fi connection and weather-based adjustments are working correctly.

Zone Coverage Testing

We run each zone and verify complete coverage with no dry spots, overspray onto hardscapes, or runoff. If we find coverage issues, we adjust head positions, arc settings, and nozzles to optimize water distribution.

Damage Report

After the full inspection, we provide you with a detailed report of any issues found — from minor adjustments to components that need replacement. You will know exactly what your system needs and can make informed decisions about repairs.

When to Schedule Spring Startup

In the Chicagoland area, the ideal time for spring startup is typically mid-April through May, after the risk of hard freezes has passed. Starting too early risks freeze damage to newly pressurized lines, while starting too late means your lawn goes without water during critical early-season growth.

Spring is our busiest season — we recommend scheduling your startup in March to secure your preferred date in April or May.
