Irrigation & Sprinkler System Repair in Chandler, AZ
We diagnose and repair the valves, timers, and lines that keep Chandler yards watered correctly through the summer heat. That covers everything from drip irrigation for xeriscape landscaping to traditional sprinkler zones.
Common Irrigation Problems We See in Chandler
A zone that won't turn off or a valve stuck open or closed are common calls. So are a timer that's stopped communicating with the controller, or a drip line with a blown emitter. These are the calls we get most often. In Chandler's climate, a broken irrigation system isn't just an inconvenience. It can mean landscaping stress within days during summer months, when plants depend on a working schedule to survive the heat.
Drip Irrigation and Xeriscape Systems
Many Chandler homes, especially in newer HOA communities that require desert-adapted landscaping, run drip irrigation rather than traditional spray sprinklers. It waters individual plants through a network of tubing and emitters, instead of covering a whole lawn area. Drip systems are efficient, but the small emitters are prone to clogging. Mineral buildup in Chandler's hard water and sun-degraded tubing after years of Arizona summers are the main culprits.
We repair and replace damaged drip lines, clogged or blown emitters, and the pressure-reducing valves that drip systems typically need. Drip tubing runs at much lower pressure than a standard sprinkler zone. A failed pressure regulator can blow out an entire line.
Diagnosing Zone and Controller Problems
When a specific zone won't turn on or won't shut off, the issue is usually the solenoid valve for that zone, not the whole system. We test each valve individually to isolate the problem, instead of replacing the whole valve manifold unnecessarily. A zone that runs constantly is often a valve stuck open by debris. Sometimes that debris can be cleared rather than the valve replaced.
Timer and controller issues are increasingly common, especially with smart or Wi-Fi-connected irrigation controllers, as more Chandler homeowners upgrade their systems. We troubleshoot whether the problem is the controller itself, the wiring to a specific valve, or the valve hardware. That way you're not replacing equipment that isn't actually the problem.
Adjusting Irrigation for Chandler's Seasons
A watering schedule that works in Chandler's mild winter is significantly undersized for July and August. Desert landscaping and lawns need substantially more frequent watering then, to survive daytime temperatures well over 100 degrees. We help homeowners adjust controller schedules seasonally, not just fix what's broken. A technically working system on the wrong schedule still leads to plant stress, or on the other end, wasted water and higher bills.
We also check for pressure problems that only show up seasonally. One example is a valve that struggles to fully open when the whole neighborhood's irrigation systems are running heaviest during peak summer watering windows. That can look like a failing valve, when it's really a shared-pressure issue affecting the whole street.
Diagnosing the Problem
| Symptom | Likely Cause | Typical Fix |
|---|---|---|
| Zone won't shut off | Solenoid valve stuck open, often by debris | Clean or replace the valve |
| Zone won't turn on at all | Failed solenoid, wiring issue, or controller fault | Diagnose and repair the specific component |
| Drip emitters clogged or not watering evenly | Mineral buildup or sun-degraded tubing | Clean, replace emitters or line sections |
| Timer or controller not running schedule | Controller fault or wiring problem | Troubleshoot and repair or replace controller |
Questions Chandler Homeowners Ask
Mineral buildup from Chandler's hard water is the most common cause, along with sun-degraded tubing after years of Arizona summer exposure. We clean or replace affected emitters and lines as needed.
We test and repair individual zones and valves rather than replacing the whole system unnecessarily, unless the system as a whole is genuinely failing.
Yes, we troubleshoot smart controllers along with traditional timers, and help determine whether an issue is the controller, the wiring, or the valve itself.
It's worth addressing quickly during summer months, since desert landscaping can show heat stress within days of an irrigation failure.
Yes, if a system is watering unevenly or wasting water on areas that don't need it, we can recommend adjustments to zones, emitters, or head placement rather than just repairing what's broken.
It depends on where it is and whether it changes when the irrigation system is off. A wet spot that stays wet even with the irrigation system shut off points toward the home's main water line instead, which our water line repair page covers.

Irrigation systems require a working backflow preventer, and many Chandler properties are required to have it tested annually. See our backflow testing and prevention page for what that involves.
