How Often Should Irrigation Systems Be Inspected in Arizona?
Arizona's extreme heat, hard water, and intense UV exposure accelerate irrigation system wear. Regular inspections prevent costly repairs, water waste, and landscape damage.
Recommended Inspection Schedule
Arizona's climate is uniquely harsh on irrigation systems. Summer temperatures exceeding 115°F, intense UV radiation, hard water mineral buildup, and monsoon storms all contribute to faster component degradation than in milder regions. A proactive inspection schedule saves money and protects your landscape investment.
Professional Inspections: Twice Yearly
Schedule professional inspections in early spring (March) and fall (October). Spring inspections prepare your system for peak summer demand, while fall inspections address wear from heavy use and prepare for winter dormancy.
What's included: Zone testing, leak detection, pressure measurement, valve inspection, controller programming review, head cleaning/adjustment, and coverage analysis.
Homeowner Visual Checks: Monthly
Between professional visits, run each zone monthly and look for obvious problems: broken heads, leaks, dry spots, overspray onto hardscapes, or zones that won't activate. Catching issues early prevents minor problems from becoming expensive repairs.
Quick checklist: All zones activate, no visible leaks, spray patterns cover intended areas, no pooling water, controller displays correct time/date.
After Major Weather Events: Immediate
Monsoon storms, high winds, or rare freezing temperatures can damage exposed components. Inspect your system within 24 hours after severe weather to identify broken heads, shifted risers, or debris-clogged nozzles before the next watering cycle.
System Startup and Winterization: Annually
While Phoenix rarely freezes, higher-elevation areas (Carefree, Cave Creek, North Scottsdale) may need winterization. Even in the Valley, reducing watering frequency in winter requires controller adjustments. Professional startup in spring ensures optimal performance for the demanding summer ahead.
Why Arizona Systems Need More Frequent Inspections
Compared to cooler, wetter climates, Arizona irrigation systems face unique challenges:
- Extreme heat: Plastic components become brittle, seals dry out, and UV radiation degrades materials faster.
- Hard water: High mineral content clogs nozzles, builds up in valves, and reduces system efficiency.
- Heavy usage: Systems run daily for 6-8 months, accumulating wear much faster than in regions with natural rainfall.
- Desert landscaping: Drip systems for native plants require frequent emitter cleaning due to dust and debris.
- Monsoon damage: Sudden storms can shift heads, flood valve boxes, or wash away soil around risers.
What Professional Inspections Catch
DIY visual checks are valuable, but professional inspections identify hidden problems that cost hundreds or thousands to fix if left undetected:
Cost of Neglecting Inspections
Skipping regular inspections may seem like a cost savings, but the consequences are expensive:
- A single undetected mainline leak can waste 10,000+ gallons per month ($100+ in water bills)
- Dead turf or plants from coverage gaps cost hundreds to thousands to replace
- Valve failures that could have been caught early require emergency repairs at premium rates
- Overwatering from controller errors promotes fungus, root rot, and weed growth
- Mineral buildup left unchecked eventually requires full system replacement

Frequently Asked Questions
How often should irrigation systems be inspected in Arizona?
In Arizona's harsh climate, professional inspections should occur twice yearly - once in early spring before peak watering season and once in fall before winter dormancy. Monthly visual checks by homeowners help catch problems early.
What happens during a professional irrigation inspection?
A thorough inspection includes testing each zone, checking for leaks, measuring water pressure, inspecting valves and controllers, cleaning or replacing clogged heads, adjusting spray patterns, and verifying proper coverage and run times.
Can I inspect my own irrigation system?
Yes, monthly visual inspections are recommended. Run each zone, look for broken heads, leaks, dry spots, or overspray. However, professional inspections catch hidden problems like underground leaks, pressure issues, and valve malfunctions that aren't visible.
How much does an irrigation system inspection cost?
Basic inspections typically range from $75-$150, often waived if repairs are needed. This small investment prevents costly water waste and landscape damage from undetected problems.
