Annual backflow tests in Shavano Park go to SAWS or the local water utility. We test, repair failed checks, and file the report.
North central estates with complex systems. 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.
Backflow Testing & Repair in Shavano Park
This is a Bexar County route we run weekly. We do not treat Shavano Park 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) Certified test with a calibrated gauge.
2) Rebuild checks if the assembly fails.
3) Retest and document.
4) File with the local water utility.
Local conditions
Hard water in Bexar County scales nozzles. Limestone and clay shift heads. If you want the neighborhood page, see sprinkler repair in Shavano Park.
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 Shavano Park 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

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 Shavano Park 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 Shavano Park 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 Shavano Park calls after the next landscaper or freeze.
