A sewer line gives you warning before it fails completely. The trick is reading the signs early, while you still have options, instead of waiting for sewage in the basement. Here are the seven that matter most in Kansas City.
The seven signs
- Slow drains all over the house. One slow sink is a local clog. Every drain slow at once points to the main line.
- Gurgling toilets. Air bubbling back through the toilet when you run water or flush means the main line is partly blocked.
- Sewage backing up into a basement floor drain or the lowest tub. That is the clearest sign of a main-line problem.
- A sewage smell in the yard or around the foundation, even faint, suggests the line is cracked or leaking.
- A soggy or unusually green patch of lawn. A leaking sewer line fertilizes and waters the grass above it, so one bright green strip can mark the break.
- Frequent clogs. If you are snaking the line every few months, something structural is catching, often roots.
- Foundation or yard settling in a line over the sewer run can mean soil is washing into a cracked pipe.
What to do next: get a camera in the line
Here is the single most useful step, and it is the one we always start with. A sewer camera inspection sends a camera down the line so you can see exactly what is wrong and where, instead of guessing or digging blind. It tells you whether the pipe is clogged, cracked, root-filled, bellied, or collapsed, and that diagnosis decides the repair. Never agree to a major dig before someone has actually looked inside the pipe.
The bottom line: these signs rarely improve on their own. Catching them early usually means a no-dig fix is still on the table. A camera inspection is the cheap, decisive first move.
The good news on the repair
If the pipe is cracked or root-filled but not collapsed, it can usually be fixed without trenching your yard. Pipe lining forms a new pipe inside the old one. For a line too far gone to line, pipe bursting replaces it without a full-length trench. Either way, see our sewer line repair page for how the diagnosis leads to the fix.

What are the first signs of a sewer line problem?
The earliest signs are usually slow drains throughout the house at once and gurgling toilets. As it worsens you may see sewage backing up into a floor drain, a sewage smell outside, or a soggy, unusually green patch of lawn over the line.
Why is one patch of my lawn greener than the rest?
A leaking sewer line releases water and nutrients into the soil above it, so the grass directly over a break often grows greener and faster, or the ground stays soggy. It is a common sign of a cracked underground line.
Should I get a sewer camera inspection?
Yes, before any major repair. A camera inspection shows exactly what is wrong and where, so you fix the real problem and avoid an unnecessary dig. It is the standard first step for diagnosing a sewer line.
Can a failing sewer line be fixed without digging up my yard?
Often, yes. If the pipe is cracked or root-filled but still structurally in place, trenchless pipe lining repairs it through small access points. A collapsed line may need pipe bursting, which also avoids a full-length trench.
