The High-Water-Bill Mystery: How Round Rock Homeowners Find Hidden Leaks Fast
The water bill is the first detective
A water bill that jumps without a change in household habits is almost always telling you something. When the checklist runs out, electronic leak detection finds what the eye cannot. The meter records every gallon that passes through it. If the total is higher than the same month last year, either someone in the house is using more water or the supply system is losing water without any fixture being open. The second scenario is a leak, and it is more prevalent than most homeowners expect.
Round Rock Utilities provides a usage comparison on the bill that shows this month versus the same month a year ago. An increase of 20 percent or more with no obvious explanation, no new family members, no pool refill, no irrigation enlargement, is worth investigating. The meter can tell you whether there is a leak right now in about two minutes.
The two-minute meter test
Switch off every fixture and water-consuming appliance in the house, including the ice maker, the sprinkler controller, and any tankless water heater that might cycle. Go to the water meter and read the dial. Wait five to ten minutes without running anything. Read the dial again. If it moved, water is leaving the system while nothing is turned on. You have a pressurized seep somewhere between the gauge and the fixtures.
Narrowing it down: inside or outside
If the meter verifies a leak, the next step is determining whether the loss is on the supply side of the main shutoff or inside the house on the fixture supply lines. Locate your main shutoff valve, turn it off fully, and then go back to the meter. If the meter indicator stops, the leak is inside the house, downstream of the shutoff. If it continues to spin, the leak is between the meter and the shutoff valve, which means it is in the buried service line under the yard.
A buried service line leak in a Round Rock yard may never surface as a apparent wet patch if the home is on the limestone west side, where water drains into the rock quickly. On the clay east side, a line leak eventually produces a soft strip in the yard, but it can take weeks to appear. The meter test is faster and more reliable than watching the yard.
Common hidden leak locations in Round Rock homes
Once you know the leak is inside the house, the most probable locations depend on the age and construction of the home. In homes from the 1980s and 1990s with copper supply under the slab, the most common source is a pinhole in the buried copper. In two-story homes, a supply leak between floors shows as a ceiling stain in the room below. A leaking toilet produces a silent loss that the meter test catches but that produces no visible water. An irrigation system with a stuck-open valve or a broken lateral loses water whenever the controller runs a cycle, sometimes invisibly in the soil.
A methodical check covers the toilets first with a dye test, then every sink cabinet for moisture. The water heater connections come next. If the obvious locations check out and the meter is still moving, the leak is likely in the slab or in an in-wall supply line, and detection tools are needed. Call (512) 737-6168 for a systematic examination that finds the source without guesswork.
When to stop investigating and call a plumber
The do-it-yourself investigation described above can confirm whether a leak exists and roughly whether it is inside or exterior the house. Beyond that point, locating a slab leak, an in-wall supply leak, or a buried yard line leak requires acoustic equipment, thermal imaging, and pressure testing tools that most homeowners do not have. Attempting to find these leaks by opening walls or breaking concrete without confirming the location first creates additional repair costs without necessarily finding the origin.
If the meter test confirms a leak and the visible check of common locations turns up nothing, call a technician with detection equipment before opening anything. A precise locate before the first hole is cut is always less expensive than an exploratory investigation. Call (512) 737-6168 and we can find where the water is going.
What happens after you call a plumber
In a Paloma Lake home or any Round Rock neighborhood, when the visible checklist does not find the source of a high water bill, calling a plumber for slab leak detection is the right subsequent step. Here is what a thorough investigation looks like so you know what to expect.
The first step is the meter test confirmation. We run it ourselves at the start of every investigation, because the result tells us whether the leak is active at that moment or intermittent. An active meter turn means a pressurized supply leak is running right now. An intermittent turn means the meter only moves during certain conditions, like when the irrigation runs or when the hot water heater cycles, which narrows the search significantly.
The second step is the isolation test: close the main shutoff and recheck the meter. Inside versus outside tells us which detection tools to deploy first. For an inside leak with no visible source, we set up acoustic equipment on the floor to listen for vibration from a slab breach. Thermal imaging then identifies the temperature contrast of a wet area behind a wall or ceiling. For an outside leak, we EM-trace the service line and acoustic-correlate along the path before any shovel touches the yard.
The third step is the locate. By the end of the detection phase, we typically have a confirmed source or a short list of candidates to verify. For a slab leak, we confirm with helium if the acoustic signal is ambiguous before the core goes in. For an in-wall leak, we confirm with an ultrasonic contact probe before the drywall opens. The repair only starts after we are certain of the location.
Most Round Rock hidden leak investigations take two to three hours for a single-source problem. Multi-source problems typically resolve in the same visit when the detection equipment can relocate across the property. A two-source invoice costs more than a single-source visit. It is far less than the alternative: a separate service call, a second access cut, another month of charges, and the structural damage that accumulated while the second source ran undetected. A two-source investigation on the same day eliminates that risk. Multi-source problems take longer but are manageable within one visit in most cases. Call (512) 737-6168 when the checklist has run out and you still have an unexplained bill.
