Zone valves are the hydraulic heart of an irrigation system. When a diaphragm tears, a solenoid fails, or grit seats incorrectly, you get zones that won’t open, won’t close, or weep water into the landscape.
Our technicians open valve boxes, test solenoids, rebuild or replace valves, and correct common manifold issues found on aging Houston systems.

Houston-specific notes
Harris County clay and construction sediment are hard on valve seats. We clean manifolds carefully and recommend filters where repeated debris failures appear on commercial sites.

Valve Repair & Replacement FAQs
Should I replace the valve or just the solenoid?
If the valve body and diaphragm are sound, a solenoid often fixes an electrical no-open. If the valve weeps or fails manual operation, a rebuild or full replacement is the durable fix.
Can you find buried valve boxes?
Yes. We use wiring paths, as-built clues, and probe techniques to locate lost boxes common after landscape renovations.
