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 Richardson 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 Richardson'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. Most 1955–75 originals in Richardson Heights, Canyon Creek, and Duck Creek long predate that rule and will happily run through a storm — the kind of waste Richardson's ordinance treats as a violation. We can add a wireless rain/freeze sensor to most controllers in a single visit.

We offer same-day or next-day service for most Richardson 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.

From April 1 through October 31, Richardson limits sprinkler watering to two days a week: even-numbered addresses water Tuesdays and Saturdays, odd-numbered addresses water Wednesdays and Sundays, with no sprinkler use between 10 a.m. and 6 p.m. From November through March you keep the same two days but may water at any time of day — a freeze-safety allowance so overnight runs don't ice the sidewalks. We set your controller to your correct schedule 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 Richardson's 1955–75 originals the culprit is often a seized brass valve with no rebuild parts left, 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 Richardson calls — we're about 12 minutes away, straight down US-75 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 Richardson's 1950s–60s originals 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. Six decades of mulch, sod, and landscaping bury valve boxes on older Richardson properties — Richardson Heights and Canyon Creek especially. We locate them electronically by tracing the valve wiring — no exploratory digging across your lawn — then raise the boxes to grade and document the system so the next repair does not require a search party.

Yes — Richardson's ordinance makes a misbehaving system a violation, and a smart controller is the cheapest compliance officer you can hire. It holds your Tuesday/Saturday or Wednesday/Sunday days, skips watering when rain or freeze is coming, and satisfies the rain/freeze shut-off requirement in one device. On Richardson's older systems we often pair it with fresh wiring in the same visit. We install and program them to your address's schedule.
