Yes. Texas law requires anyone who installs, alters, repairs, or services an irrigation system for compensation to hold a TCEQ irrigator or irrigation technician license. Eldorado Sprinkler Repair & Irrigation is owned and operated by a Texas Licensed Irrigator, LI0026061 — ask any company for their LI number before they touch your system.

Yes. Much of our Allen work is on systems installed decades ago by companies that no longer exist. We service all major brands — Rain Bird, Hunter, Toro, Irritrol, Weathermatic — and can match or retrofit parts on older systems.

Yes. We repair and replace double check valve assemblies and other backflow preventers that fail Allen's required annual test. We're not a testing company; we're the licensed irrigator who fixes what the testers flag, usually within a day or two — and we coordinate the retest with your tester so you close out compliance in one cycle. Details on our backflow repair & replacement page.

If your system was installed since 2009, Texas rules required it to include rain/freeze shut-off technology — and Allen goes further: running sprinklers during rain or a freeze is a violation whether you have a sensor or not. A working sensor is the cheapest insurance against that, and we can add a wireless one to most controllers in a single visit.

We offer same-day or next-day service for most Allen calls — our shop is in east Plano, about 12 minutes away, so you're not waiting on a crew crossing the Metroplex. Call (469) 970-2715 and describe the problem; we'll give you an honest arrival window.

Allen assigns watering days by neighborhood, not by even/odd address. From April through October you may water up to twice a week on the days shown for your home on the city's watering map — search “Find My Watering Day” at cityofallen.org. From November 1 through March 31, watering drops to once weekly on your Primary Watering Day. No sprinkler use between 10 a.m. and 6 p.m. April through October, and running sprinklers during rain or freezing weather is a violation. We set your controller to your assigned days on every visit.

A single dead zone usually means a failed solenoid, a cut or corroded field wire, or a bad controller station — the valve itself is often fine. We test the wiring path with a multimeter before replacing anything, which is how we keep repairs to the part that actually failed. See sprinkler wiring & controller repair.

A zone that runs until you kill the water at the backflow valve is a stuck valve — debris lodged in the diaphragm or a diaphragm worn through. On old Allen's 1970s–80s originals we often find the whole manifold at end of life, and we'll tell you honestly whether one valve or a rebuild is the cheaper path over five years. See sprinkler valve repair & replacement.

Same-day or next-day for most Allen calls — we're about 12 minutes from our east Plano shop. In peak summer season the schedule fills by early afternoon, so call in the morning if you can. Either way, you get an honest arrival window when you call, not a four-hour maybe.

The service call fee covers a full system diagnosis and is applied to your repair — so if we do the work, the diagnosis effectively costs nothing. We quote a flat price after diagnosis and you approve it before any work begins. What we do not do: free estimates that turn into pressure to sign on the spot.

Most single repairs are finished the same visit — a head replacement or solenoid swap takes 30–90 minutes after diagnosis. Bigger jobs like a manifold rebuild or a deep lateral-line repair usually take a half day. We tell you the time along with the flat rate before we start.

Usually not. If we can reach the controller (or it is a smart controller we can access with your permission) and the gates are open, most repairs happen without you. We send photos of the finished work, and you are welcome to a walkthrough by phone after the system test.

Not the full blowouts northern states need — DFW systems stay charged year-round. What matters here is protecting the above-ground backflow assembly before hard freezes and having a working freeze sensor. Every February we repair the split backflows and burst manifolds of homeowners who skipped both; an insulated cover costs almost nothing by comparison.

Repair, in most cases — even 1970s old-Allen systems usually have sound pipe, and replacing components as they fail costs far less than a new system. We recommend full replacement only when the pipe itself is failing in multiple places or the layout no longer fits the landscape. If that is your situation, we will say so plainly. See sprinkler system installation.

Yes. Decades of mulch, sod, and landscaping bury valve boxes on older Allen properties — old Allen east of US-75 especially. We locate them electronically by tracing the valve wiring — no exploratory digging across your lawn — then raise the boxes to grade so the next repair does not require a search party.

Yes — and Allen will help pay for it. The city offers rebates on water-saving upgrades like smart controllers, plus free residential sprinkler system evaluations. A Rachio or Hunter Hydrawise holds your neighborhood's assigned days, switches to your Primary Watering Day for winter, and skips watering when rain or freeze is coming — which in Allen also keeps you clear of the no-watering-during-rain rule. We install and program them to your address's schedule.
