Frequently Asked Questions
How much does irrigation valve repair cost in Phoenix?
Irrigation valve repair in Phoenix typically costs $75–$175 per valve, depending on the type (solenoid, ball, gate, or anti-siphon) and whether the manifold or wiring needs replacement. Diagnostic fees are usually $65–$95 and applied toward the repair. Arizona Irrigation Repair LLC provides upfront pricing before any work begins.
How do I know if my irrigation valve is bad?
Six common signs of a failing irrigation valve: (1) one zone stays on even when the controller is off — stuck-open valve; (2) one zone never activates — stuck-closed valve or failed solenoid; (3) water seeps from the valve box — diaphragm leak; (4) chattering or buzzing noise from the valve box — solenoid voltage issue; (5) water hammer when zones cycle — faulty check valve; (6) zone activates only manually but not automatically — wiring or solenoid fault.
How long does an irrigation controller last?
A quality irrigation controller typically lasts 8–15 years. Factors that shorten lifespan include power surges, direct sun exposure, moisture intrusion, and outdated firmware. Smart Wi-Fi controllers (Rachio, Hunter Hydrawise) tend to last 7–12 years before hardware limitations make replacement more cost-effective than repair.
Why is my sprinkler timer not working?
The seven most common causes are: (1) power failure or tripped breaker; (2) programming lost after power outage; (3) dead or weak backup battery; (4) rain sensor override active; (5) wiring fault between controller and valve; (6) controller circuit board failure; (7) smart controller Wi-Fi or app connectivity issue. Most can be resolved without replacing the entire controller.
Can I replace an irrigation valve myself?
Replacing a solenoid (the top portion of the valve) is a DIY-friendly repair — it costs $15–$40 in parts and takes about 20 minutes. Replacing the full valve body requires shutting off the main water supply, cutting into the manifold, and solvent-welding PVC — a job best left to a licensed irrigation technician to avoid leaks and code violations.
What is the difference between a solenoid valve and a ball valve in irrigation?
A solenoid valve is an electrically-operated valve that opens and closes automatically based on signals from the irrigation controller — used for zone control. A ball valve is a manual shutoff valve used to isolate sections of the system for maintenance. Most residential irrigation systems have both: solenoid valves at each zone manifold and ball valves at the main supply line.
How do I reset my irrigation controller after a power outage?
Most controllers retain programming if the backup battery is fresh. If programming is lost: (1) replace the 9V backup battery; (2) set the current date and time; (3) re-enter your zone run times and start times; (4) check that the seasonal adjustment is set to 100%; (5) run a manual cycle to confirm all zones activate. Smart controllers (Rachio, B-Hyve) automatically restore programming from the cloud after reconnecting to Wi-Fi.
How often should irrigation valves be inspected?
Arizona Irrigation Repair LLC recommends inspecting irrigation valves twice per year — once in spring before the summer watering season begins (March–April) and once in fall after the monsoon season ends (October–November). Annual inspections catch diaphragm wear, solenoid corrosion, and manifold leaks before they cause water damage or landscape loss.
What brands of irrigation controllers do you repair?
We repair and replace all major irrigation controller brands including Rain Bird, Hunter, Orbit, Toro, Irritrol, Weathermatic, Rachio, RainMachine, B-Hyve, and Netafim. We stock common replacement parts for Rain Bird and Hunter systems and can typically complete same-day repairs for most controller issues in the Phoenix Metro area.
Is it worth repairing an old irrigation controller or should I replace it?
If your controller is under 8 years old and the repair cost is under 50% of a new unit, repair is usually the better value. If it's over 10 years old, consider upgrading to a smart Wi-Fi controller — they typically save 20–50% on water bills through weather-based scheduling, pay for themselves in 1–2 seasons in Arizona's climate, and qualify for SRP and APS rebates of $25–$100.
