Sewer line cleaning clears the main pipe that carries all of your home's wastewater to the public sewer or septic tank. It's needed when several drains back up at once. A plumber typically works through an outdoor cleanout using a heavy cable machine with root-cutting heads or a hydro jetter, and often follows up with a camera inspection.
Signs of a main sewer line problem
- Water or sewage comes up in the tub or shower when you flush a toilet
- Several fixtures are slow or clogged at the same time
- The basement or lowest floor drain backs up
- Gurgling toilets after running the washer or dishwasher
- A sewage smell inside or around the yard
- Soggy, sunken or unusually green patches over the sewer line route
Sewer backups are among the most urgent plumbing calls because untreated wastewater can enter the living space. If it's happening now, stop running water and call 123456789 — we'll connect you with a provider offering emergency plumbing services in Maryville.
What causes sewer line blockages?
Tree roots
Roots are drawn to the moisture in sewer pipes and enter through joints and small cracks. Older clay and cast-iron lines with more joints are especially vulnerable, and established Maryville neighborhoods with mature trees see this often.
Grease, wipes and buildup
Everything that goes down every drain passes through the main line. Over years, grease and "flushable" wipes combine into blockages that a fixture-level fix can't reach.
Sagging or damaged pipe
A section of pipe that has settled — called a "belly" — holds water and solids. Shifting clay soils and age can cause sags, offset joints or cracks. Cleaning helps temporarily, but repeat clogs usually mean a camera inspection is worthwhile.
Heavy rain
Some homeowners notice slow drains after heavy storms. Groundwater can enter cracked lines, and an overloaded public system can make problems worse. If backups only occur during storms, mention that to the provider and your sewer utility.
How sewer cleaning works
- Locate the cleanout. Most homes have a capped pipe outside near the foundation or in the yard. Without one, access is through a toilet or roof vent — and some providers will recommend installing a cleanout.
- Clear the line. A sectional or drum cable machine with cutting heads breaks through clogs and cuts roots. For grease and sludge, jetting scours the pipe walls.
- Inspect. A sewer camera shows roots, breaks, sags and the condition of the pipe, and can locate problem spots from the surface.
- Recommend next steps. That might be nothing more, routine maintenance cleaning, or a repair if the camera finds damage.
Sewer clean-out service
A cleanout is the access point that lets a plumber reach your main line without pulling a toilet. If yours is buried, broken or missing, ask the provider about locating or adding one — it makes every future drain cleaning call faster and easier.
Who's responsible for the sewer line?
Generally, the property owner is responsible for the private sewer lateral running from the house toward the public main, and the utility maintains the public sewer. Exactly where that responsibility changes depends on your utility and property. In Maryville, Alcoa and other parts of Blount County, your water and sewer provider can tell you where their responsibility begins. Homes outside city sewer service often use a septic system, which has different maintenance needs — tell the plumber if you're on septic.
What affects the cost of sewer service?
Each provider sets their own prices. Typical factors include cleanout access, line length, whether roots must be cut, jetting versus cabling, camera inspection, excavation if repairs are needed, and after-hours timing. Ask for a clear explanation of what's included before work starts.
