When a zone in San Antonio will not run right, we trace the fault instead of guessing at heads. Most calls are a solenoid, a buried head, a leak, or a controller output — sometimes two of those stacked.
Citywide coverage on limestone and clay soils. San Antonio irrigation lives with limestone, caliche, pockets of black clay, Edwards Aquifer hard water, and long hot summers. Those conditions scale nozzles, walk heads out of grade, and punish weak valves.
Sprinkler System Repair in San Antonio
This is a Bexar County route we run weekly. We do not treat San Antonio like a generic Texas suburb — the soil, the water, and the HOA clock on this street are what set the repair.
How the visit goes
1) Run every zone and mark the fault.
2) Test controller output and solenoid resistance.
3) Repair the failed part with a matched replacement.
4) Re-run and arc-adjust the affected zone.
Local conditions
Hard water in Bexar County scales nozzles. Limestone and clay shift heads. If you want the neighborhood page, see sprinkler repair in San Antonio.
What you can do before we arrive
Write down the station number, whether it fails only after rain, and whether the controller shows an error. Those three notes cut diagnostic time.
Parts and brands
Rain Bird, Hunter, Toro, Irritrol, Weathermatic, and K-Rain parts are not always interchangeable. On San Antonio systems we document what is in the ground and match precipitation rates so one head does not drown a bed while another dusts the turf.
If a model is discontinued we install the closest hydraulic match and tell you what changed. We do not leave a mixed zone that cannot be scheduled honestly.

Quick question
Why did only one zone die? Because each zone has its own valve and wire. A dead station is usually that circuit, not the whole irrigation system.
When to call
Call Sprinkler Repair Tech if a zone will not shut off, water is pooling toward a foundation, or half the yard is offline in San Antonio heat. Those are same-week jobs. Tune-ups and audits book on the next route day.
We are a call-first repair company. Technicians carry solenoids, diaphragms, spray bodies, rotors, and nozzle trees so most San Antonio repairs finish in one visit. You get a plain-language explanation of what failed and how to water the soil you actually have.
Photograph the controller program before any upgrade. Label the valve box once we find it. Those two habits prevent a lot of repeat San Antonio calls after the next landscaper or freeze.
