To fix a smart sprinkler system, call a licensed irrigation contractor, also known as a sprinkler repair company. Irrigation contractors service every part of a smart system: the Wi-Fi controller, the low-voltage wiring, the valves and solenoids, the pipes, the sprinkler heads and drip lines, the backflow preventer, and the watering schedule. Call the controller manufacturer’s support line only for app, account, Wi-Fi pairing, or firmware problems. Call an electrician only if the outlet or circuit that powers the controller is dead. Call a plumber only if the leak is on your home’s main water line rather than on the irrigation system. In Las Vegas, the right call is a Nevada-licensed C-10 landscape irrigation contractor who services smart controllers such as Rachio, Rain Bird, Hunter Hydrawise, and Orbit B-hyve.
The reason is simple. A smart sprinkler system is a conventional sprinkler system with a connected controller on top. The app and the weather-based scheduling are new, but the water still moves through the same valves, wires, pipes, and heads that irrigation technicians have repaired for decades, and that is where most failures happen. This guide explains who to call to fix a smart sprinkler system for each type of problem, what to check before you pick up the phone, and why systems in Las Vegas, Henderson, North Las Vegas, and Summerlin break in ways that systems elsewhere do not.
In this guide:
A smart sprinkler system is an irrigation system run by a Wi-Fi-connected controller that you program and monitor from a phone app. Instead of running fixed start times, the controller adjusts watering using local weather data, seasonal evapotranspiration rates, and inputs from optional sensors such as a rain and freeze sensor, a soil moisture probe, or a flow meter that detects leaks. Common residential brands include Rachio, Rain Bird, Hunter Hydrawise, Orbit B-hyve, and Toro.
Everything downstream of the controller is standard irrigation hardware:
When something goes wrong, the controller usually reports the symptom, but the cause is almost always in one of these components. That is why the answer to who to call to fix a smart sprinkler system is nearly always the same professional who fixes a traditional one.
An irrigation contractor, sometimes listed as a sprinkler repair company or sprinkler technician, is trained on the whole system from the controller to the last emitter. In Nevada, irrigation work is performed under a State Contractors Board C-10 landscape contracting license, and companies in that classification routinely diagnose smart controllers, replace failed solenoids and valves, trace and splice broken wires, locate underground leaks, repair backflow preventers, and reprogram schedules to match the Southern Nevada watering seasons. Call an irrigation contractor when:
A good contractor also carries the parts that fail most often in the desert, so most smart sprinkler repairs are completed in a single visit. See our overview of irrigation repair services for the full list of what a technician can handle.
Rachio, Rain Bird, Hunter, Orbit, and the other controller brands all run support lines and online help centers for their apps. They are the right call when the hardware is fine but the software is not:
Manufacturer support cannot send someone to your yard, and they cannot tell you whether a zone failed because of a solenoid, a cut wire, or a stuck valve. If support confirms the controller itself is faulty and it is out of warranty, an irrigation contractor can replace it and re-wire the zones in the same visit.
Smart controllers plug into a standard 120-volt outlet through a small transformer, usually in the garage or on an exterior wall. If the controller is completely dark and the reset button on the GFCI outlet does not bring it back, test the outlet with another device. A dead outlet, a breaker that keeps tripping, or a damaged exterior receptacle is a job for a licensed electrician. If the outlet works and the controller is still dark, the transformer or the controller has failed, which is back in the irrigation contractor’s territory.
Plumbers work on the pipes that carry water to and inside your home. Irrigation contractors work on everything after the irrigation shut-off valve, and in Las Vegas that includes the backflow preventer. Call a plumber when the water meter keeps moving with the irrigation shut-off valve closed, when there is a wet spot between the meter and the house, or when the leak is at a hose bib, on the main line, or indoors. If you are not sure which side the leak is on, our guide to telling an irrigation leak from a main water line leak walks through the test.
Many lawn maintenance crews will straighten a tilted head, swap a nozzle, or clear a clogged emitter while they are on site, and that is fine. Diagnosing a smart controller, replacing valves, or repairing wiring is a different trade. Unless your landscaper holds an irrigation contractor license, they are limited to small handyman-level jobs, and a crew that guesses at an electrical or valve problem can leave you with a bigger repair bill. For anything beyond a head or an emitter, hire an irrigation contractor.
Garages and side yards are often at the edge of a home’s Wi-Fi range, and stucco walls and metal garage doors block signal. If the controller drops offline repeatedly and manufacturer support has ruled out the device, the fix is a mesh node or range extender near the controller, or moving the controller closer to the router. Most irrigation contractors can relocate a controller; the network itself is a job for your internet provider or a home network installer.
If you rent, or if the sprinkler system waters common areas, check your lease or CC&Rs before scheduling anything. Many Las Vegas HOAs own the irrigation on front yards and shared landscapes and contract their own irrigation company, and some require that repairs be approved before work starts. Report the problem to the manager with a photo of the controller screen or a screenshot of the app alert so the right company is dispatched.
Use this table to decide who to call to fix a smart sprinkler system based on what you are seeing.
| What you see | Most likely cause | Who to call |
|---|---|---|
| Controller screen is dark and the app shows it offline | Tripped GFCI outlet, failed transformer, dead outlet | Reset the GFCI first; then an irrigation contractor for the transformer or controller, an electrician for the outlet or circuit |
| Controller has power but the app says offline | Wi-Fi dropout, router change, weak signal in the garage | Manufacturer support to re-pair the controller; a Wi-Fi extender if the signal is weak |
| One zone will not run | Failed solenoid, broken wire, bad zone terminal | Irrigation contractor |
| No zones run but the controller works | Closed shut-off valve, master valve failure, broken common wire, active rain sensor | Irrigation contractor |
| A zone will not shut off | Debris under the valve diaphragm, failed solenoid, stuck master valve | Irrigation contractor, same-day if the yard is flooding |
| Weak spray, dry spots, heads not popping up | Leak, cracked lateral line, clogged filter, too many heads on one zone | Irrigation contractor |
| Water bill jumped with no visible leak | Underground leak, slow-seeping valve, zone running unnoticed at night | Irrigation contractor for leak detection |
| Water spraying or dripping at the backflow preventer | Freeze damage, worn seals, failed poppet | Irrigation contractor (PVB repair) |
| Meter keeps moving with the irrigation shut-off closed | Main line or house-side leak | Plumber |
| System waters on the wrong days or ignores the schedule | Weather skip settings, wrong time zone, overlapping programs, outdated seasonal schedule | Manufacturer support for app settings; irrigation contractor to program the SNWA schedule and verify run times |
| Repeated high-flow or leak alerts from a flow sensor | Broken head, line break, miscalibrated sensor | Irrigation contractor |
| App login, account transfer, or firmware errors | Software | Manufacturer support |
Five minutes of checks can save a service call fee or help the technician arrive with the right parts.

The Mojave Desert is hard on irrigation equipment, and smart controllers add a few new failure points of their own.
An irrigation contractor who works in Las Vegas every day recognizes these patterns quickly, which is a strong argument for hiring locally rather than relying only on manufacturer support.
A professional smart sprinkler system repair in Las Vegas usually follows the same sequence:
Many smart sprinkler repairs are completed in one visit of one to two hours. Underground leak detection, wire tracing, and multi-valve replacement take longer.
Prices vary with the brand of controller, the number of zones, and how far a leak or wire break is from the valve box, but these are typical ranges for smart sprinkler system repair in the Las Vegas Valley:
| Repair | Typical cost |
|---|---|
| Diagnostic or service call | $75 to $150, often credited toward the repair |
| Solenoid replacement | $85 to $175 per valve |
| Control valve replacement | $150 to $350 per valve |
| Wire tracing and splice repair | $100 to $300 |
| Transformer or power supply replacement | $75 to $150 |
| Smart controller replacement (parts and labor) | $200 to $450 |
| Backflow preventer (PVB) repair or rebuild | $150 to $450 |
| Underground leak location and pipe repair | $200 to $600 |
Because a service call costs less than most of the repairs it prevents, the earlier you call when a zone misbehaves, the smaller the bill. For a complete installation price breakdown, see how much a new sprinkler system costs in Las Vegas.
The controller is the one component where replacement often beats repair. Consider replacing a smart controller when:
A WaterSense-labeled smart controller typically cuts outdoor water use by 15 to 30 percent compared with a fixed-schedule timer, and the Southern Nevada Water Authority has offered rebates and coupons on qualifying controllers through its conservation programs, so ask your contractor what is currently available. When the controller is healthy and the fault is in a valve, a wire, or a head, repairing is almost always the right choice.

Call a licensed irrigation contractor. Sprinkler repair companies diagnose controllers, valves, wiring, pipes, and heads in a single visit, which is faster and usually cheaper than calling a plumber, an electrician, and the manufacturer separately. Call a plumber only if the leak is on your home’s main water line, and an electrician only if the outlet that powers the controller is dead.
Generally no. Plumbers work on the water supply to and inside the house. Irrigation systems, including the backflow preventer, valves, wiring, and controller, are a separate trade handled by licensed irrigation contractors. The exception is a leak on the main line before the irrigation shut-off valve, which is plumbing work.
An electrician can restore power to the outlet or circuit that feeds the controller, but most do not service irrigation controllers, zone wiring, or valves. If the outlet works and the controller is still dead or misbehaving, call an irrigation contractor.
The manufacturer’s support team handles app, account, Wi-Fi pairing, and warranty issues. A local irrigation contractor handles everything physical: installation, replacement, wiring, valves, sensors, and programming to the local watering schedule. Most contractors service all major brands.
For anything beyond a small handyman-level job, yes. Landscape irrigation work in Nevada falls under the State Contractors Board’s C-10 classification, and a licensed contractor is bonded, insured, and accountable for the work. Unlicensed repairs can also void warranties and create problems with your HOA or a future home sale.
Yes. A valve stuck open wastes hundreds of gallons an hour, floods the yard, can undermine walkways and foundations, and may lead to water-waste fines. Close the irrigation shut-off valve at the backflow preventer, then call for same-day sprinkler repair.
Most smart sprinkler repairs in Las Vegas fall between $100 and $450, depending on whether the fix is a solenoid, a valve, a wire splice, or a controller replacement. Underground leaks and multi-zone problems cost more. A diagnostic visit is typically $75 to $150 and is often credited toward the repair.
Often, yes. Experienced local contractors carry common solenoids, valves, wire, heads, emitters, and controller transformers on the truck, so most single-zone problems and controller swaps are completed on the first visit. Leak location in caliche soil or special-order parts can require a second trip.
