Why homeowners call us
We diagnose before we dig
San Antonio limestone, caliche, hard water, and heat cycles are hard on irrigation. Most systems we see have three or four small problems compounding into one big symptom. We test every zone, check controller output, trace field wiring, and confirm the fault before a shovel comes off the truck.
- Zone-by-zone run test on every visit
- Wire tracing to locate buried valve boxes
- Parts matched to your existing heads and nozzles
- Arcs, radius, and schedule corrected before we leave

Common questions
How do I know if my sprinkler system has a leak?
The most common signs are a spike in your water bill, a section of lawn that stays soggy between cycles, and a drop in pressure across multiple zones. If the meter's low-flow indicator moves while every zone is off, water is escaping somewhere in the system.
Why is one zone not turning on?
Nine times out of ten it is a solenoid valve, a broken field wire, or a bad controller output. A technician can isolate which of the three it is in a few minutes by testing resistance at the controller terminal.
How often should a sprinkler system be inspected?
Twice a year is ideal for the San Antonio area: once at spring startup and once before the first hard freeze. An annual audit at minimum will catch buried heads, misaligned arcs, and slow leaks.
Is backflow testing required in Texas?
Yes. Irrigation systems connected to a public water supply must have their backflow prevention assembly tested annually by a licensed tester, and the results filed with the local water authority.
How long should each zone run?
It depends on head type, soil, and sun exposure. Rotor zones on clay typically need longer cycles split into two shorter runs so water can soak in, while spray zones on beds usually need much less. We set this during a tune-up.
Can you find a valve if I don't know where it is?
Yes. We use a wire tracer to follow the field wiring from the controller to the valve, which locates buried boxes without trenching across the yard.

What San Antonio homeowners say
“They found a bad solenoid in under twenty minutes and had the zone running before lunch.”
“Three heads were buried under clay. They reset everything and the brown patch greened up within a week.”
“A zone would not shut off overnight. They rebuilt the valve, checked the manifold, and it held pressure.”
