Your sewer lateral is the pipe that carries waste from the house out to the public sewer. Nobody thinks about it until it fails. In Fayetteville, where the median home was built in 1984 and 44.1% of homes date from before 1980, many laterals have been underground for forty years or more, and age, roots and heavy rain all take a toll.
Why sewer lines fail
Tree roots.
Roots look for water and find it at small gaps in old joints. Once inside, they grow and catch paper and waste.
Older pipe materials.
Depending on when a house was built, the lateral may be clay, cast iron or an early plastic. Each ages in its own way: clay joints shift, cast iron corrodes from inside.
Settling and sags.
Soil settles over time, leaving low spots where waste collects.
Heavy rain and flooding.
Fayetteville averages about 44.58 inches of rain a year, and Hurricane Helene brought severe flooding to parts of the city. Saturated soil puts extra water into a cracked line and can shift damaged pipe.
Past patch jobs.
Older lines often have repairs made with mixed materials.
Warning signs
- More than one drain slow at the same time.
- Toilets bubbling or gurgling when another fixture runs.
- Water backing up into a tub or shower, especially after rain.
- A sewage odor in the house or yard.
- A wet, sunken or unusually green strip of lawn between the house and the street.
- The main line needs clearing again and again.
Start with a camera inspection
Before anything is dug up, ask for a sewer camera inspection. The plumber feeds a small camera through a cleanout and records the inside of the line. You can see the problem for yourself, whether it is roots, a crack, a sag or a collapsed section, and how far it is from the house. Ask for a copy of the video. It makes quotes easier to compare and is useful paperwork if you sell.
Repair options
What the plumber recommends depends on what the camera shows:
Clearing and root cutting
when the pipe is sound but blocked. Roots often grow back, so ask how long the fix is likely to last.
Spot repair,
digging down at one broken section and replacing it.
Full replacement
when the line is cracked or sagging in several places.
Trenchless methods
such as lining the old pipe from inside, where the line is suitable. Not every line is.
Ask what the price includes: digging, backfill, restoring the yard or driveway, and any permit. Inside city limits, the City of Fayetteville Development Services office handles permits, and outside the city Cumberland County does.
Buying or selling in Fayetteville
With Fort Bragg next door, many Fayetteville homes change hands on short military timelines. A standard home inspection usually does not look inside the sewer line. For a house built before 1990, a camera inspection before closing is a modest cost compared with finding a broken lateral after you move in.
Landlords
Repeat backups in a rental are frustrating for everyone. A camera inspection settles whether the problem is something tenants are flushing or a failing pipe that needs repair, and gives you a record to keep with the property.
Common questions
How can I tell if my sewer line is damaged?
Look for several slow drains at once, gurgling toilets, backups after rain, or a sewage smell. A camera inspection is the only way to be sure.
Do roots really break sewer pipes?
Roots get in through small gaps at joints, then grow and widen them. Over time they can crack pipe and block it completely.
Will my yard be dug up?
Not necessarily. A camera pinpoints the problem. A single break may need one small dig, and some lines can be lined from inside without a trench.
