Valve Repair & Replacement in Houston

Stuck, leaking, and weeping valves rebuilt or replaced.

A failing solenoid valve is the most common reason a zone runs when it shouldn't or refuses to shut off. We locate buried valves, rebuild diaphragms where it makes sense, and replace valve bodies and manifolds that have reached end of life.

Signs you need this service

  • A zone that keeps running after the controller shuts down
  • Constant trickle from the lowest head on a zone
  • Humming from the valve box with no water flow
  • Standing water or erosion around the manifold

How we handle it

  1. 1 Locate buried valve boxes with a wire tracer
  2. 2 Test solenoid resistance and controller output
  3. 3 Rebuild or replace the valve and clean the manifold
  4. 4 Pressure-test the zone under full flow

What customers say about our work

4.9 average from 12 customer reviews
“Two zones had quit on us and another company told us the whole manifold had to be replaced. The tech from Reliable traced it to a bad solenoid and a nicked wire, fixed both, and ran every zone with me before he left. Straight answers the whole way through.”
Marcus D. Katy, TX · Valve Repair & Replacement · June 9, 2026
“Our water bill nearly doubled and we could not find the cause. They located a cracked lateral under the side yard in about forty minutes, repaired it, and put the sod back so neatly you cannot tell where they dug.”
Priya S. Sugar Land, TX · Leak Detection & Repair · May 28, 2026
“Eleven heads replaced and every arc reset. The shade zones under the oaks were drowning and the sunny strip was burning up — they rebalanced the whole thing and the lawn evened out within two weeks.”
