Sprinkler Leak Detection and Repair in Round Rock, TX
Sprinkler leaks divide neatly between what you can see and what you cannot. A leaking head or riser shows itself while the zone runs. A break in the buried lateral feeding the heads stays hidden until the water finds its way up.
Leaks you can see versus leaks underground
The sprinkler hardware you see above ground, pop-up heads and rotors, can fail at the seal inside the head or at the riser that screws into the lateral below. A lateral tee connection to the supply is another common spot. Run a zone and walk it. A head that geysers around its base has a bad wiper seal. A riser that weeps at the connection has a cracked or overtightened joint. A head that does not pop up in a low corner points at the lateral below. Those are all above-ground or shallow repairs.
What you cannot see is a split in the buried lateral between the zone valve and the heads. That type leaks whether the zone is running or off, and it shows as a soggy strip across the lawn rather than a single wet head.
Running each zone to find the source
We run each zone in turn and walk every head, watching for water at the base of the body, around the riser, or pooling at the tee. A head with a bad seal or a cracked body shows quickly. A zone that runs wet in one strip regardless of head position points us to the lateral below. We also check the zone valve itself, since a solenoid that sticks open lets the zone run unscheduled, inflating the bill without any head obviously misbehaving.
If a zone is always wetter than it should be, or a strip stays soggy, call (512) 737-6168 and we can isolate it.
Head, riser, and tee repairs
Most visible sprinkler repairs are quick. A head with a worn seal gets a new body or just the internal capsule replaced, depending on the brand. A cracked riser is swapped out. A leaking tee in the shallow lateral gets dug to and rejoined with the right fitting for that pipe type. We match parts to the existing brand and nozzle type so zone coverage stays what it was designed to be, rather than swapping heads at random and leaving dry spots.
Solenoid and valve repairs
A zone valve that will not close drains the lateral every time the zone finishes, and a valve that sticks open runs the zone constantly against the schedule. We test each solenoid and diaphragm while the system is running and replace failed components individually, rather than swapping the whole manifold when one valve is the culprit. Sonoma Ridge and Round Rock Ranch, where original irrigation systems went in with the neighborhood, have manifolds old enough that diaphragms and solenoids now fail regularly.
Replacing only the failed component rather than the full manifold keeps the cost proportional to the problem and leaves the working valves in place. A manifold that is otherwise sound does not need to come out because one solenoid gave up.
Why fixing a sprinkler leak matters during restrictions
With outdoor watering limited to assigned days in 2026, a leaky zone running off-schedule is both wasteful and a potential violation. Texas summers heat a lawn fast enough that a soggy zone is hard to miss, but a lateral weep in a low-coverage corner can run unnoticed for months. The hard water here scales up inside sprinkler heads over time and makes seals stiffen and fail sooner. Catching a wet zone early keeps the repair at a head or a riser, not a torn-up lawn. Call (512) 737-6168 if a zone is behaving wrong.

📞 (512) 737-6168Frequently Asked Questions
How do I know if it is the head or a buried pipe?
Run the zone and walk it. A wet head or a riser that weeps is above-ground hardware. A soggy strip across the lawn that persists between heads usually points at the buried lateral below.
Why does one zone run even when not scheduled?
Usually a stuck solenoid or a worn diaphragm in the zone valve. It lets the zone stay open after the controller shuts it off. We test and replace the failed valve component.
Do you match replacement heads to the existing system?
Yes. We match the brand, nozzle type, and arc to the existing heads so coverage stays as designed, rather than introducing dry spots or over-spray by mixing incompatible parts.
