Prevent Problems.
Protect Your Property.

Most commercial irrigation systems benefit from scheduled inspections at least four times per year, with additional visits during peak watering months or on large, high-use properties. A consistent maintenance schedule helps Koster Irrigation identify leaks, damaged heads, coverage problems, and controller issues before they cause costly landscape damage or excessive water use.

A typical visit includes a system-wide operational check, sprinkler head inspection and adjustment, leak detection, valve and zone testing, controller review, coverage evaluation, and identification of worn or damaged components. Koster can also document findings and recommend repairs or efficiency improvements based on the needs of your property.

Yes. Correcting hidden leaks, overspray, poor coverage, incorrect run times, and malfunctioning valves can significantly reduce avoidable water use. Preventive maintenance also helps ensure each landscape area receives the appropriate amount of water instead of relying on longer run times to compensate for system problems.

Early spring is ideal for system startup and correction of winter damage. Midseason inspections help optimize performance during hot, dry weather, while fall service prepares the system for cooler conditions and changing watering needs. Commercial properties often benefit from a year-round plan rather than waiting for visible problems.

Yes. Koster technicians can review controller programming, seasonal run times, rain or weather sensor operation, and zone schedules. These adjustments help match irrigation to current landscape conditions, plant needs, sun exposure, soil characteristics, and seasonal weather patterns.

Common warning signs include unusually high water bills, soggy areas, dry or stressed turf, water spraying onto pavement, low pressure, heads that do not rise or rotate, zones that will not shut off, and inconsistent coverage. Prompt inspection can prevent a small malfunction from becoming a larger repair.

Koster Irrigation can provide clear findings, note priority repairs, and recommend practical improvements for system performance and water efficiency. This documentation is especially useful for property managers, facility teams, homeowners associations, municipalities, and organizations responsible for multiple locations.
