A sprinkler that keeps running after the controller is off, or a zone you cannot stop at the timer, comes down to one thing: a bad valve. Whether it is blasting at full pressure or just weeping and refusing to fully close, the valve is the culprit.
It is one of the most misdiagnosed problems in irrigation. Homeowners see water at a head, assume the head failed, and unplug the controller hoping that stops it. It does not, because the controller is not what is holding the valve open. By the time most people call Brandon, they have already cut power to the timer and the zone is still running.
The real cost here is water, and it adds up fast at full flow. The good news is the fix is well understood: get the water shut off at the backflow so it stops wasting, then have the specific valve rebuilt or replaced. Everything below walks through why it happens, how to stop it right now, and exactly how Brandon repairs it in Plano.
What is actually going on
A valve stuck open at full pressure
Grit or debris under the diaphragm holds the valve wide open, so a zone runs at full flow even with the controller unplugged. The controller is not the problem. The valve is.
A valve that will not fully close
Just as common: the zone will not shut off all the way and keeps weeping or trickling from the heads. A worn diaphragm or seat keeps the valve from sealing. Still the valve, not the head.
Unplugging the timer does not fix it
Most people have already cut power to the controller before they call, and it keeps running anyway. That confirms it is mechanical, at the valve. Controllers do not get stuck on.
How Brandon fixes a sprinkler that will not shut off
It is always the valve, so that is where Brandon starts. He isolates the specific valve feeding the zone that will not stop, then opens it up to see what is keeping it from seating. Usually it is grit or a torn diaphragm holding it open, sometimes a failed solenoid.
From there it is a rebuild or a replacement. If the valve body is sound, he rebuilds it with new internals and it seals like new. If it is cracked, corroded, or too worn to trust, he replaces the whole valve so you are not back to the same problem in a season.
The work itself is where experience matters in Plano. Builder-grade valve boxes here are cramped, often with two valves crammed in one box and the solenoid wire buried under the pipe during backfill. The boxes fill with dirt over the years because they were never lined with rock. Getting a valve out and back in cleanly without nicking a wire or a fitting is careful work, not a quick parts swap.
You get an upfront flat-rate quote after the diagnosis, before any work begins. If Brandon opens the box and finds more going on than expected, he stops and tells you what he found before he proceeds. No surprise invoices, and the same technician who diagnosed it does the repair.
Honest, flat-rate pricing
No hourly clock, no surprise invoices. You know the number before any work starts.
Priced upfront, flat-rate
Brandon diagnoses the actual problem first, then quotes a fixed price. You approve it before a shovel touches the ground. No meter running, no padding the hours.
If it turns out worse, you decide
If the box comes open and there is more going on than expected, Brandon stops and tells you what he found before proceeding. You are never surprised by the invoice.
Break a pipe digging? Price stays the same
Digging in shifting clay near roots and old fittings carries risk. If something breaks getting to the repair, that is on Brandon, not your bill. Time-and-materials shops charge you for the accident. He does not.
Same tech, 3-year warranty
Brandon shows up himself, every visit, so your system gets diagnosed once and remembered. Repairs are backed by a 3-year warranty on the work.
Sprinkler Won't Shut Off in Plano
Plano's Blackland clay expands and contracts hard with the seasons, and that constant ground movement is tough on valve boxes, fittings, and diaphragms. It is a big part of why valves here fail earlier than the box on the shelf would suggest.
The older systems in Willow Bend, Stonebriar, Deerfield, and West Plano are where Brandon sees the most stuck-valve calls. Many of those systems have original valves with 15 to 20 years on them, sitting in builder-grade boxes that have slowly packed with dirt. When the diaphragm finally gives up, the zone will not shut off.
Brandon shows up himself, every visit. Same technician means your system gets diagnosed once and remembered, not rediscovered from scratch on every call. He services Plano across 75023, 75024, 75025, 75075, and 75093.
