Understanding Sewer Line Repair Services
Your home’s sewer line is one of the most critical components of your plumbing system. When it fails, the results can be messy, smelly, and expensive. Understanding your options for sewer line repair can help you make informed decisions and find the right plumber for the job.
This guide covers everything you need to know about sewer line problems, repair methods, and how to find a qualified sewer line specialist in Chattanooga.
Signs of Sewer Line Problems
Sewer line issues often develop gradually, but catching them early can save you thousands in repairs. Watch for these warning signs:
- Multiple slow drains – When several drains in your home are slow simultaneously, the problem is likely in your main sewer line.
- Sewage backups – Water or sewage coming up through floor drains or toilets indicates a serious blockage.
- Gurgling sounds – Strange noises from toilets or drains when using water elsewhere suggest sewer line issues.
- Foul odors – Sewage smells in your yard or home indicate a leak or break in the sewer line.
- Lush patches in your yard – Unusually green or fast-growing grass over the sewer line may indicate a leak fertilizing the soil.
- Soggy areas in your yard – Wet spots or sinkholes near the sewer line suggest a break.
- Foundation cracks – Severe sewer leaks can undermine your foundation, causing cracks.
- Pest problems – Rats and insects are attracted to sewer line breaks.
- Mold growth – Excess moisture from sewer leaks can cause mold in your home.
Causes of Sewer Line Damage
Understanding what causes sewer line problems can help you prevent them:
Tree Root Intrusion Tree roots are the most common cause of sewer line damage in Chattanooga. Roots seek out moisture and nutrients, and your sewer line provides both. Even small cracks allow roots to enter, where they grow and eventually block or break the pipe.
Aging Pipes Older homes in Chattanooga may have sewer lines made of clay, cast iron, or Orangeburg (tar paper) that deteriorate over time. These materials have a lifespan of 50-75 years and may need replacement.
Ground Shifting Tennessee’s clay soil expands and contracts with moisture changes, putting stress on underground pipes. This can cause joints to separate or pipes to crack.
Grease Buildup Grease poured down drains solidifies in sewer lines, gradually restricting flow until complete blockage occurs.
Flushing Inappropriate Items Flushing anything other than toilet paper and human waste can cause clogs. “Flushable” wipes are a major culprit despite their marketing.
Bellied Pipes When a section of pipe sinks due to soil conditions, it creates a low spot where waste collects and causes recurring blockages.
Sewer Line Services Explained
Video Camera Inspection Before recommending repairs, professional plumbers use waterproof cameras to inspect the inside of sewer lines. This allows them to:
- See the exact location and nature of the problem
- Identify multiple issues in one inspection
- Provide accurate repair estimates
- Show you the problem on video
Sewer Line Cleaning For clogs and minor buildup, plumbers offer professional sewer line cleaning using:
- Motorized drain snakes for breaking up blockages
- Hydro jetting for thorough cleaning and root removal
- Root cutting tools for tree root intrusion
Traditional Sewer Line Repair For severe damage, traditional excavation may be necessary. The plumber digs down to the damaged section, replaces it with new pipe, and restores your yard. While more invasive, this method is sometimes the most cost-effective option for extensive damage.
Trenchless Sewer Repair Many plumbers now offer trenchless repair methods that minimize disruption to your property:
Pipe Lining (CIPP): We insert a resin-coated liner into the existing pipe, which hardens to create a new pipe within the old one. This is ideal for pipes with cracks, small holes, or joint separation.
Pipe Bursting: A new pipe is pulled through the old one, breaking apart the damaged pipe as it goes. This is effective for severely damaged pipes that need complete replacement.
Sewer Line Replacement When repair isn’t feasible, complete sewer line replacement may be necessary. A good plumber will help you understand your options and choose the best solution for your situation and budget.
The Typical Sewer Line Repair Process
- Initial Assessment – The plumber discusses your symptoms and schedules an inspection.
- Camera Inspection – The entire sewer line is inspected to identify all issues.
- Diagnosis & Options – You receive an explanation of the problem and repair options with pricing.
- Repair Work – Once approved, the repair is completed using the agreed-upon method.
- Final Inspection – The line is re-inspected to ensure the repair was successful.
- Cleanup & Restoration – The property is restored and the work area cleaned up.
Preventing Sewer Line Problems
- Don’t plant trees near sewer lines – Keep large trees at least 10 feet from your sewer line.
- Dispose of grease properly – Never pour grease down drains.
- Only flush appropriate items – Toilet paper and human waste only.
- Schedule regular inspections – Camera inspections every few years can catch problems early.
- Consider root treatment – Chemical root treatments can slow root growth in your sewer line.

- Equipment – Ensure they have camera inspection and appropriate repair equipment
- Experience – Sewer work requires specialized skills; ask about their experience
- Methods – Ask if they offer trenchless options
