Water Line Leak Detection and Repair in Round Rock, TX
One pipe brings all your water from the city meter to the house. When that main service line leaks, the whole home feels it through weak pressure and a bill that climbs.
When the main water line fails
The service line is the single pipe carrying every gallon from the meter into the house, so a leak there hits everything at once. Pressure sags at the farthest fixtures, the bill jumps without a change in habits, and the meter keeps turning after dark. A bad enough break shows as water bubbling up near the meter box or along the path to the house. A smaller one gives no surface sign at all, only the steady creep of the meter.
In Paloma Lake and similar newer neighborhoods, these lines are often poly or PEX and run a fair distance from the street, so a small split can quietly waste water for weeks.
A failing main shows up in subtler ways too. Air or sputtering at a faucet when you first turn it on, a faint hiss near the meter box, or hot and cold sides that no longer balance can trace back to the service line. None of these prove a leak alone, but with a moving meter they build the case. The sooner the main is checked, the smaller the bill that has been quietly climbing.
Tracing the service line
We confirm the loss at the meter first, then trace the service line to map its exact route and depth. Listening equipment follows the run and peaks over the break, and a pressure test on the isolated line proves whether the main is the culprit or whether the leak sits elsewhere. That tells us where to open and, just as important, where not to.
If your pressure has dropped across the whole house and the bill climbed with it, call (512) 737-6168 and we can check the main line directly.
Spot repair or full line replacement
A single break in a sound line gets repaired at the marked spot with a small dig. When the line is old, undersized, or already patched, replacing the whole run is the honest fix. A trenchless pull installs a fresh line along the old path with access pits at each end, which spares the yard and driveway. We walk you through both, with the cost of each, before any digging starts.
Pressure, hard water, and the main
The main line takes a steady beating. Full city pressure pushes on it constantly, and Round Rock water near 15.2 grains per gallon leaves scale that narrows older lines over time. A line that has carried hard water for decades, or one stressed by shifting clay soil, is the one that finally splits. The repair restores both the pressure and the flow the rest of the house depends on.
How to tell the main from a fixture
Before assuming the service line, we separate it from a leak inside the house. With the home shut off at the main valve, a meter that keeps moving means the loss is upstream, on the buried service line itself. A meter that stops means the leak is somewhere past the valve, inside the walls or under the slab. That one test decides where we focus.
It matters because the two repairs are different jobs. A service-line fix happens out in the yard, often trenchless, while an interior leak is found and opened inside the house. Getting the split right the first time keeps you from paying to chase the wrong pipe. If your pressure dropped across the whole house at once, call (512) 737-6168 and we will start at the main.

📞 (512) 737-6168Frequently Asked Questions
Why is my whole house low on pressure?
A leak or a scaled, narrowed main service line drops pressure everywhere at once. We test the main directly to confirm before recommending a repair or replacement.
How can a main line leak if I see no water?
The line is buried, so it can leak underground for weeks while only the meter and the bill show it. Tracing finds the break without digging blindly.
Is replacing the line better than repairing it?
One break in good pipe is a spot repair. An old, scaled, or repeatedly patched line is usually better replaced, often trenchless, so you are not back at it next year.
