Valve Repair in Grogan's Mill

Grogan's Mill is the oldest village. That means big pines, original PVC, and fittings that have been glued more than once. Roots lift laterals. Valve boxes disappear under thirty years of needles. A dead station here is often a solenoid in a buried box, not a new clock.

A diaphragm that will not seat keeps a zone running after the clock shuts off. A burned solenoid keeps it dead. Valve boxes in The Woodlands fill with needles and mud, so we locate the box, test the coil, and rebuild or replace on the spot. This page is the valve repair path for Grogan's Mill.

What we look for

• A zone that will not shut off
