FAQs
What signs indicate I might have a leak in my main water line?
Common indicators include a sudden spike in your water bill, the sound of running water when fixtures are off, soggy or unusually green patches in the yard, reduced water pressure inside the home, and visible cracks or potholes in your driveway or sidewalk. In Chattanooga’s clay-rich soil, leaks can also create small sinkholes because water erodes the ground more rapidly.
How does professional leak-detection equipment find hidden main-line leaks?
Our certified technicians use a combination of acoustic listening devices, ground-penetrating radar, thermal imaging, and tracer gas technology. Acoustic sensors pick up the distinct sound frequencies produced by escaping water, while thermal cameras reveal temperature changes in the soil. Tracer gas (a safe mix of hydrogen and nitrogen) can be introduced into the line; sensitive detectors then locate where the gas escapes, pinpointing the leak without excavation.
Is leak detection in Chattanooga disruptive to my landscaping or driveway?
No. Modern leak-detection tools allow us to locate leaks to within a few inches, greatly reducing or eliminating exploratory digging. Once the leak is pinpointed, only a small, targeted excavation is needed for repair. This minimally invasive approach protects your lawn, hardscapes, and mature trees, which are common features in many Chattanooga neighborhoods.
How long does a typical main-line leak detection and repair take?
Most residential leak-detection visits are completed in 1–2 hours. If a repair is needed, many can be finished the same day, depending on pipe depth, soil conditions, and permitting requirements. For larger or deeper lines, or if extensive tree-root intrusion is found, repairs may extend to the next business day, but we always provide a clear time estimate before work begins.
Will Chattanooga’s high water-table and heavy rainfall affect the accuracy of leak detection?
Our equipment is calibrated for local conditions, including the Tennessee River’s influence on groundwater levels. Advanced filtering algorithms in acoustic gear distinguish between leak noises and background water movement. Additionally, tracer gas and thermal imaging are not affected by saturated soils, ensuring reliable results even after heavy storms.
What should I do while waiting for a professional if I suspect a main-line leak?
Locate and shut off your home’s main water valve to prevent further water loss and property damage. Document any visible signs of the leak (wet spots, foundation cracks) with photos. Avoid using plumbing fixtures until we arrive, and contact your utility provider to report unusually high meter readings if applicable. Prompt action reduces repair costs and helps protect Chattanooga’s water resources.
