10 Signs of Sewer Line Damage

These signs mean "look at the lateral," not "buy a full replacement today." A lateral is the pipe from your house to the city main. The sewer line replacement cost page prices that work after you know what failed. A camera inspection, at $100–$500, is the step that sorts a clog from a broken pipe.

Ten signs worth a closer look

1. Several fixtures drain slowly at once. One sink can be a local clog. A tub, a toilet, and a floor drain together point at the shared line.
2. A toilet or tub gurgles when another fixture drains. Air is moving because the line is restricted.
3. A sewage smell indoors, especially near a floor drain or in a basement.
4. A sewage smell in the yard, stronger after you do laundry or run a shower.
5. A soggy strip, or a patch of grass that is much greener than the rest, over the path of the lateral.
6. A dip or soft hole in the yard along that same path.
7. Backups into a tub, shower, or floor drain, even if they recede.
8. Roots in a cleaned-out clog. Roots enter at joints. Clay pipe is known for that, with a published life of 50–60 years.
9. Recurring clogs a few weeks after snaking. The snake cleared a symptom and left the crack or the sag.
10. A known Orangeburg, cast iron, or clay lateral plus any of the signs above. Age is context. Orangeburg's published life is 30–50 years, and cast iron's is 50–75 years. The camera is the test.

None of these signs, alone, names the repair. Two or three together are a reason to stop repeat snaking and film the pipe. More symptom detail and the price of the visit are on the camera inspection page.

What the fix can cost

A belly is a sag that holds waste. The repair cost page is the decision table in longer form. If sewage has entered the house, cleanup is an extra $500–$10,000.

What the signs do not prove

A smell does not prove the city owes you a repair. A dip in the yard does not prove insurance will pay. Wear is not covered by a standard homeowners policy. The responsibility guide and the insurance guide are the next reads if the video shows a real break. A service line endorsement, if you already have one, runs about $30–$40 a year in the published data and is not something you can usually buy after the failure to cover that failure.

Do not start excavating because the grass is green. Tree roots and irrigation can green a lawn too. The camera is cheaper than a trench you did not need.

Worked example

You notice gurgling and a slow floor drain. You pay the low camera fee, $100, or as much as $500.

If the video shows a sound pipe and a single clog, you have spent the inspection fee and avoided a replacement you did not need. For a 40-foot line on a suburban lot in the Mountain / Southwest region, bursting would have been about $6,200–$10,000 with a permit.

If the video shows a collapse, that bursting range becomes the plan, not a surprise. The inspection did not create the cost. It stopped you from buying lining at $135–$150 per foot for a pipe that cannot hold a liner.

How to save money

• Note which fixtures misbehave, and when, before you call.
• Book a camera instead of a third snake if the clog returned.
• Ask for the video file the same day.
• Do not approve a replacement from a phone description of the video.
• Match the method to the picture: line a round pipe, replace a collapsed one.
• Ask the city and your insurer only after you know there is a break.
