Sewer line problems announce themselves in unpleasant ways: a rotten smell in the yard, a patch of ground that stays wet, drains that gurgle or back up, or dampness creeping along the foundation where the line exits the house. By the time you notice, the line has usually been failing for a while.
Finding the problem used to mean digging up the yard along the suspected route and hoping. We do it differently. A camera goes into the line through a cleanout, travels the full run to the street, and shows us the pipe's interior on a monitor in real time. A locating transmitter on the camera head then tells us exactly where that defect sits underground, so we can mark it on the surface. One hole, in the right place.
What Are the Signs of a Sewer Line Leak?
- Sewer odors indoors or in the yard. A persistent rotten-egg or sewage smell, especially near drains or in one area of the yard, means wastewater is escaping the pipe.
- Soggy or sunken ground along the sewer route. The line usually runs fairly straight from the house to the street. Wet, lush, or sunken patches along that path are a strong indicator.
- Slow drains or gurgling fixtures. When several fixtures drain slowly at once, or toilets gurgle when the washer runs, the main line may be partially blocked or collapsed.
- Moisture along the foundation. Where the sewer exits the house, a leak can keep the soil against the foundation constantly wet.
- An unusually green strip of grass. Wastewater is fertilizer. A stripe of thick green grass tracing the sewer route is a classic sign.
If sewage is actively backing up into the house, that is an emergency. Call (972) 945-2293 now and see our emergency leak detection page.
How Does Sewer Camera Inspection and Locating Work?
The visit follows a straightforward sequence.
Access through the cleanout. Most homes have a cleanout, usually a capped pipe near the house or in the yard. The camera enters there, so there is no digging to start the inspection.
A full video run. The camera head, with bright lights, travels the line to the city connection. You watch the same monitor the technician watches. We record the run so you have video evidence of the pipe's condition.
What we look for. Cracks and fractures in the pipe wall, separated or offset joints, bellies (low spots where waste collects), scale buildup, and root intrusion. Each defect gets noted with its distance from the cleanout.
Locating from above ground. The camera head carries a transmitter. The technician walks the yard with a receiver that picks up the signal and pinpoints the defect's position and depth. That spot gets marked with paint or flags.
A written report. You get the video file or a link to it, still images of each defect, the marked locations, and our findings in plain language. Hand it to a sewer contractor for a repair quote, or keep it as documentation.
Why Do Sewer Lines Fail in Flower Mound?
- Tree roots in wooded lots. This is the big one locally. Flower Mound's mature trees send roots hunting for moisture, and a sewer line is a constant water source. Roots enter through tiny joint gaps or cracks, then expand and break the pipe further. Older clay or concrete pipe is the most vulnerable, but roots can exploit any joint.
- Expansive clay soil movement. Wet-dry soil cycling shifts the ground around the pipe, stressing joints until they separate or offset. A separated joint is both a leak and a root invitation.
- Age. Many Flower Mound homes are old enough that their original sewer lines are reaching the end of their service life. Corrosion, scale, and simple material fatigue accumulate over decades.
- Bellies from poor original bedding. Some lines were laid with low spots that collect solids. A belly does not leak on its own, but the standing waste accelerates corrosion and blockage at that point.
What Happens After We Locate the Defect?
Your report and video give any sewer contractor everything needed to quote the repair: the defect type, its exact location and depth, and the pipe's overall condition. Common fixes include a spot repair at the marked location, a trenchless liner for cracked but intact pipe, or a full replacement for collapsed lines. Because the location is marked, the contractor digs once.
If your symptoms turned out to be a water supply issue rather than a sewer issue, our water line leak detection covers that side. And if the moisture is under the slab rather than in the yard, start with slab leak detection.
