Common issues found during a sewer inspection

A sewer line problem is not always obvious until the warning signs become hard to ignore. Slow drains, recurring clogs, unpleasant odors, or backups can all point to issues deeper in the system. A sewer inspection helps identify what is happening below the surface so homeowners can make more informed decisions before a smaller issue becomes a more expensive one.
Understanding the kinds of problems often found during a sewer inspection can help you know when it may be time to schedule one.
Blockages and buildup
One of the most common things found during a sewer inspection is blockage. Grease, debris, paper buildup, and other materials can restrict flow over time and increase the risk of drainage problems or backups.
Even if water is still moving, a partial blockage can cause drains to slow down and create recurring issues throughout the home. That is one reason professional evaluation matters when clogs keep coming back.
Cracks or broken pipe sections
Sewer lines can develop cracks, fractures, or broken sections as they age. Shifting soil, ground movement, wear, and past damage can all contribute to pipe deterioration. These issues may allow waste or water to move where it should not, and they can interfere with proper system performance.
A sewer inspection can help reveal whether the line is structurally sound or whether repairs are needed.
Corrosion or aging pipe wear
Older sewer lines may show signs of corrosion, scale, or general wear. As materials deteriorate, the line may become more vulnerable to blockage, leaks, or collapse. Aging infrastructure is not always obvious from inside the home, which is why an inspection can be helpful when plumbing issues seem repetitive or hard to explain.
Bellies or sagging sections
A sewer line should maintain proper flow, but sometimes parts of the line sink or sag. These low spots, sometimes called bellies, can allow waste and water to collect rather than move cleanly through the system. Over time, that can lead to repeated clogs, slow drains, and performance problems.
This type of issue is not always visible without an inspection, but it can have a major effect on drainage.
Root intrusion
Trees and landscaping can affect underground plumbing lines. Root intrusion happens when roots find their way into small openings or weak spots in the sewer line. Once roots enter, they can continue growing and create more serious restrictions or damage.
Homeowners may first notice the problem as recurring drain issues or backup symptoms. An inspection can help confirm whether root intrusion is present and how serious it has become.
Misaligned or separated joints
Sewer lines made of multiple connected sections can develop problems at the joints. Misalignment, separation, or loose connections can interfere with flow and create opportunities for leaks or intrusion. This is especially important in older systems or in areas where ground conditions have shifted over time.
Why early inspection matters
A sewer line issue that goes undiagnosed can continue getting worse. What starts as a drainage inconvenience may eventually lead to backups, property disruption, or larger repair needs. A professional sewer inspection helps identify the source of the problem more accurately, which can lead to a more effective solution.
