Green Guru Irrigation Guide
A healthy irrigation system depends on many mechanical and electrical parts working together. In Rochester Hills homes, some problems show up more often than others, especially as systems age through multiple Michigan seasons.

Common categories are valve issues, damaged heads, uneven coverage, underground leaks, and controller or wiring faults. The right fix depends on which part of the system is causing the symptom.
| What you notice | What usually needs inspection |
|---|---|
| Vibration, clicking, or unstable zone flow | Valve internals, pressure, or debris |
| Broken spray or pooling at one head | Sprinkler body, nozzle, or riser area |
| Dry patches or overwatered areas | Coverage pattern, nozzle choice, or pressure balance |
| Wet ground or pressure loss | Underground pipe leak or damaged lateral line |
| Zones not starting correctly | Controller, wiring, or valve signal path |
A properly functioning irrigation system helps maintain healthy lawns and landscapes throughout the Michigan growing season. However, sprinkler systems contain many mechanical components, and occasional problems can occur over time.
Below are several issues commonly encountered in irrigation systems serving homes throughout Rochester Hills and the surrounding Oakland County area.
Irrigation valves control water flow to each sprinkler zone. Over time, valves may develop problems due to mineral buildup, debris inside the valve, worn diaphragms, or pressure irregularities.
These issues can cause valves to vibrate, chatter, or fail to open fully.
Sprinkler heads are exposed to lawn equipment, foot traffic, and environmental conditions. Common head problems include:
Damaged heads can reduce watering efficiency and create uneven coverage.
Dry patches or overwatered areas may indicate problems with system design or adjustment. Typical causes include misaligned spray patterns, incorrect nozzle selection, pressure differences between zones, and landscaping changes that block spray patterns.
A system inspection can help restore balanced coverage.
Leaks in irrigation lines can occur due to freezing and thawing cycles, aging materials, ground movement, or accidental damage during landscaping work.
Leaks may appear as unusually wet areas or unexplained pressure loss.
Modern irrigation systems rely on electronic controllers and underground wiring. Problems sometimes occur due to damaged valve wiring, controller programming errors, power interruptions, or aging controller components.
Diagnosing these issues typically requires professional testing.
Many sprinkler system problems can be prevented with regular inspections and maintenance. Typical seasonal service includes:
Preventative maintenance helps ensure reliable operation throughout the watering season.
Sprinkler systems are an important part of maintaining healthy landscapes. When problems arise, early diagnosis helps prevent more extensive repairs.

There is no single cause on every property, but valve issues, damaged heads, uneven coverage, leaks, and controller or wiring faults are common categories.
Yes. A stuck or chattering valve may affect a single zone, while some pressure or controller issues can affect multiple zones.
Misaligned spray patterns, incorrect nozzles, pressure differences, and landscaping changes are all common causes.
Wet areas, pressure loss, or unexplained water use can all point to an underground line leak.
Seasonal service catches valve, head, leak, and performance issues earlier so they are less likely to turn into larger repairs.
