Why should I inspect my sprinkler system after a Houston freeze?
Short answer: Freeze damage may not become obvious until water pressure returns and the affected component begins leaking. A cracked backflow preventer, a split above-ground fitting, or a damaged valve can look fine all winter — and only show itself the first time the system is pressurized again in spring.
Houston freezes are usually short, which makes them easy to underestimate. But a single night in the twenties is enough to crack an exposed backflow assembly or a bare PVC fitting that still had water in it. The damage is invisible while the system is off and drained. It only becomes a leak when the supply is turned back on — and by then, water may be running into a wall, a bed, or the ground for hours before anyone notices.
The inspection is simple: turn the water on slowly, walk the system, and look at every above-ground component first — the backflow preventer, exposed pipe, valves, and fittings. Run each zone and watch the heads, the valve boxes, and the ground around the lines. A zone that will not pressurize, a head that barely rises, a valve box full of water, or a wet spot that was not there before the freeze are all signs something cracked.
If the system was shut down and drained properly before the freeze, the risk is much lower — but it is still worth checking. The cost of an inspection is small next to the cost of a cracked backflow assembly leaking unnoticed, or a mainline break washing out soil under a walkway.
What we check in Atascocita
This is a common call in Atascocita, and it is the kind of problem we test in the yard instead of guessing at from the driveway. We run the system, watch how the water is actually moving, and check the parts that cause this — before anything gets replaced. That is the same approach in the full Sprinkler Repair service page.

Frequently asked questions
What is the most common freeze damage on a sprinkler system?
The above-ground backflow preventer. It is the most expensive single component to replace and the easiest to forget, because it sits outside in the open while the rest of the system is buried and protected by the soil.
Should I turn the system on myself after a freeze?
You can, but turn the water on slowly and stay with it. Watch the backflow preventer and the valve boxes as the system pressurizes, and shut the supply off again right away if you see water spraying or pooling where it should not be.
