Sprinkler Valve Repair

A zone that will not come on, one that keeps running after the controller stops, or one that dribbles water all day. Those are almost always valve problems. Call 469-208-4222.

How a zone valve works

Each zone has an electric valve, usually in a green box in the lawn. The controller sends a small voltage to the solenoid on top, the solenoid lets water off the top of a rubber diaphragm, and line pressure pushes the diaphragm open. When the signal stops, the diaphragm closes. Dirt, wear or a bad solenoid breaks that cycle.

What usually goes wrong

Zone will not turn on: dead solenoid, cut or corroded wire, or a controller problem.
Zone will not turn off: debris holding the diaphragm open, a torn diaphragm, or the manual bleed left open.
Zone runs on its own or weeps: a worn seat or diaphragm that does not seal.
Cannot find the valve: boxes get buried under sod and mulch over the years. We locate them and bring them back to grade.

Repair or replace

Many valves can be rebuilt with a new diaphragm or solenoid. Old valves with cracked bodies or no available parts get replaced. We tell you which and why. More in what to do when a zone will not shut off.

Questions people ask us

Water keeps running after I turn the controller off. What do I do?

Close the irrigation shut-off valve near the backflow device or meter, then call us. That is a valve stuck open.

Why does one zone never come on?

Most often a failed solenoid or a cut wire. We test the circuit at the controller and at the valve to find which.
