Texas requires annual testing of irrigation backflow assemblies tied to a public water supply. In greater San Antonio that usually means SAWS or a suburban water utility.
Helotes properties in Bexar County file with whichever purveyor serves the meter. We test, rebuild if it fails, and submit the report.
What the tester is checking
RPZ and double-check assemblies have check valves that must hold. A relief port that weeps, a frozen bonnet, or a failed check means the test fails and the assembly has to be repaired before it can be certified.
Freeze damage is the winter version of this call. Exposed brass on the side of a {city} house splits when a hard north wind sits on it overnight.
Paperwork
We complete the certified test with a calibrated gauge and file it with the correct Bexar County authority. Details live on our Backflow Testing & Repair page.
Keep a photo of the assembly and last test on your phone. Realtors and HOAs ask for it.
San Antonio conditions that change the repair
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.
Helotes is in Bexar County. Hill Country edge lots with rocky soil and long laterals. That is why a generic statewide watering guide fails here — the soil does not take water the same way, and the mineral load is different.
Twice-yearly checkups (spring startup and a pre-freeze look at the backflow) catch buried heads and weak solenoids before they brown a lawn in July.

Quick question
Who gets the test report in San Antonio? SAWS or your suburban water utility. We file with the purveyor on the meter.
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 Helotes 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 Helotes 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 Helotes calls after the next landscaper or freeze.
