Sprinkler Valve, Wiring and Controller Repair in Plano
Valve rebuilds from $150; controller replacement quoted by model
The valves and the controller are the brain and the muscles of your sprinkler system. When a zone refuses to come on, runs when it should not, or the controller screen goes dark after a storm, the problem is almost always one of three things: a solenoid, a wire, or the controller itself.
Valve problems
Each zone has a valve, usually in a green box at ground level. Inside is a diaphragm and a solenoid. A torn diaphragm or debris under it makes the zone leak or stay on. A dead solenoid makes the zone never start. We rebuild valves with manufacturer kits when the body is sound, and replace the whole valve when it is cracked or an obsolete brand with no parts available. Valve boxes that have filled with dirt and roots get cleaned out so the next repair is not an excavation.
Wiring faults
Irrigation wire runs underground from the controller to every valve. It gets cut by edgers, fence posts, new plantings, and gophers. Splices made without waterproof connectors corrode within a couple of years in Collin County soil. We locate breaks with a wire tracer rather than digging up the yard, then repair with gel-filled connectors rated for direct burial.
Controller replacement and upgrades
Lightning and power surges kill a lot of controllers in Texas. If yours is dead, we can replace it with a like-for-like unit or upgrade you to a Wi-Fi smart controller such as a Rachio or Hunter Hydrawise. Smart controllers let you run zones from your phone, skip watering when rain is forecast, and hold your city's watering days without you touching them.
Rain and freeze sensors
Texas has required a rain or moisture shutoff sensor on every new automatic irrigation system since the 2009 TCEQ rules, and Allen, Wylie, Sachse and Murphy also require a freeze sensor or smart controller on new systems. If yours is missing, stuck, or wired around, we install a working one and verify the controller responds to it.
Call (972) 585-6256 and describe the symptom. A licensed tech will have the right valve kits, wire and a replacement controller on the truck.
