If the Hollywood Park system still runs in the rain, the sensor is dead or bypassed. We install or rewire the interrupt and prove it shuts down.
North SA residential with shade zones. 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.
Rain & Freeze Sensor Installation in Hollywood Park
This is a Bexar County route we run weekly. We do not treat Hollywood 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) Pick a mounting point with sky exposure.
2) Wire into the controller interrupt.
3) Test shutdown and restart.
4) Set sensitivity for local storms.
Local conditions
Hard water in Bexar County scales nozzles. Limestone and clay shift heads. If you want the neighborhood page, see sprinkler repair in Hollywood 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 Hollywood 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
My system still runs in the rain. Is the sensor broken? Either the disc is worn out or someone jumpered the interrupt. We test the circuit, not just the plastic disc.
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 Hollywood 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 Hollywood 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 Hollywood Park calls after the next landscaper or freeze.
