High static pressure in some San Antonio neighborhoods turns sprays into fog. PRS heads or a master regulator stop the mist and the waste.
Citywide coverage on limestone and clay soils. In San Antonio (Bexar County) that shows up on real systems, not in a generic statewide handout. 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.
What we do on the San Antonio visit
We start with a zone run test and a look at pressure. Then we repair the actual fault — wire, valve, head, or leak — with parts matched to the brand in the ground.

Safe DIY vs licensed work
Safe: note the station number, clear a nozzle screen, confirm the rain sensor and backflow handles. Not safe: digging a mainline, cutting poly under pressure, or wiring a new solenoid without a meter.
Local water and soil
Hard water scales nozzles in Bexar County. Limestone and clay walk heads out of grade. We reset on swing joints and match precipitation so the schedule you set actually reaches the roots.
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.
San Antonio is in Bexar County. Citywide coverage on limestone and clay soils. 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
Can you mix Hunter and Rain Bird heads on one zone? Only if precipitation rates match. Mixing a 1.5-inch spray with a rotor on the same valve makes a brown stripe.
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.
