How to Maintain Your Irrigation System in Arizona

Why Irrigation Maintenance Matters in Arizona

In Gilbert's desert climate, a well-maintained irrigation system is essential for keeping your landscape healthy while conserving water. Arizona's extreme temperatures, low humidity, and infrequent rainfall make proper irrigation critical for plant survival. Regular maintenance prevents costly repairs, ensures your plants receive the right amount of water, and helps you comply with local water conservation regulations.

A poorly maintained irrigation system can waste hundreds of gallons of water monthly, leading to higher utility bills and potential fines during water restrictions. Additionally, broken or misaligned sprinklers can create dry spots that kill plants or overwater areas, leading to disease and water waste. Regular maintenance ensures your system operates efficiently, saving water and money while keeping your landscape beautiful.

Monthly Maintenance Tasks

Perform these tasks monthly to keep your system running smoothly and efficiently:

Inspect Sprinkler Heads: Check all sprinkler heads for damage, misalignment, or clogging. Look for heads that are broken, tilted, or not popping up properly. Clean any debris from the heads and adjust direction as needed.
Check for Leaks: Walk your irrigation zones and look for signs of leaks, including soggy areas, unusually green patches, or water pooling. Leaks can waste significant amounts of water and damage your landscape.
Test Each Zone: Run each irrigation zone manually and observe coverage. Ensure all areas are being watered evenly and that there are no dry spots or overspray onto sidewalks and driveways.
Clear Debris: Remove grass, dirt, and debris from sprinkler heads that may block water flow. Trim grass around sprinkler heads to ensure they can pop up fully.
Adjust Schedules: Modify watering schedules based on season, weather conditions, and plant needs. Arizona's climate changes significantly between seasons, requiring schedule adjustments.
Monitor Water Pressure: Check that water pressure is consistent across all zones. Low pressure may indicate leaks or clogs, while high pressure can damage sprinkler heads.

Seasonal Maintenance

Different seasons in Arizona require different maintenance approaches:

Spring (March-May): Perform a full system inspection, replace damaged components, adjust for increased watering needs as temperatures rise, and reprogram controllers for spring schedules. This is also a good time to upgrade to smart controllers if you haven't already.
Summer (June-August): Monitor for increased water needs during extreme heat, check for heat-related issues like cracked pipes or damaged heads, ensure adequate coverage during peak watering times, and watch for water restrictions that may require schedule adjustments.
Fall (September-November): Prepare for reduced watering as temperatures cool, inspect the entire system before winter, clean filters and screens, and adjust schedules for reduced plant water needs. This is also the time to winterize if you're in an area that experiences freezing.
Winter (December-February): Protect from freezing if temperatures drop below 32°F, reduce watering schedules significantly, monitor for any freeze damage, and plan for spring maintenance and upgrades.

Common Irrigation Problems and Solutions

Watch for these common issues and know how to address them:

Clogged Sprinkler Heads: Mineral deposits, dirt, and debris can clog sprinkler heads. Clean by removing the head and flushing with water, or soak in vinegar to remove mineral deposits. Replace severely clogged heads.
Broken or Damaged Pipes: Look for signs of leaks, including wet spots, reduced water pressure, or unusually high water bills. Professional repair is usually needed for pipe issues.
Controller Malfunctions: Controllers can fail due to power surges, age, or programming errors. Test all programs regularly and replace outdated controllers with modern smart controllers.
Water Pressure Problems: Low pressure may indicate leaks or clogs, while high pressure can damage equipment. Install pressure regulators if needed and check for blockages.
Uneven Water Distribution: This can be caused by misaligned heads, pressure issues, or incorrect head spacing. Adjust heads, check pressure, and consider adding or relocating heads for better coverage.
Overspray: Sprinklers watering sidewalks, driveways, or streets waste water and can create hazards. Adjust head direction and consider switching to drip irrigation in narrow areas.

When to Call a Professional

While some maintenance can be DIY, consider professional help for:

System Design and Installation: Professional design ensures proper coverage, efficient water use, and compliance with local codes. New installations should always be done by licensed professionals.
Major Repairs or Replacements: Significant repairs, pipe replacements, or system upgrades require professional expertise to ensure proper installation and prevent future problems.
Controller Programming and Optimization: Smart controllers can be complex to program correctly. Professionals can optimize schedules for maximum efficiency and water savings.
Water Efficiency Audits: Professional audits identify inefficiencies, recommend improvements, and can help you qualify for water conservation rebates in some areas.
Complex Troubleshooting: If you can't identify the source of problems after basic checks, professionals have specialized tools and knowledge to diagnose issues quickly.
Backflow Testing: Many areas require annual backflow device testing by certified professionals to ensure safe drinking water.

Water Conservation Tips

Maximize water efficiency with these strategies that are especially important in Arizona:

Water Timing: Water during early morning hours (4-8 AM) when evaporation is lowest and water pressure is typically highest. Avoid watering during windy conditions.
Drip Irrigation: Use drip irrigation for plants, trees, and shrubs. Drip systems deliver water directly to roots with minimal waste and are ideal for Arizona's climate.
Hydrozoning: Group plants with similar water needs together and water them on the same zone. This prevents overwatering some plants while underwatering others.
Rain Sensors: Install rain sensors to prevent unnecessary watering during monsoon season. Modern sensors can also detect humidity and adjust accordingly.
Weather-Based Controllers: Upgrade to smart controllers that adjust watering based on weather conditions, soil moisture, and plant needs.
Regular Schedule Adjustments: Adjust schedules based on weather, season, and plant maturity. Newly planted areas need more water than established landscapes.
Mulch Application: Apply mulch around plants to retain soil moisture and reduce irrigation needs by up to 25%.
Regular Maintenance: Keep your system well-maintained to prevent leaks and ensure efficient operation. A single broken sprinkler head can waste hundreds of gallons monthly.
