Signs Your Sewer Lines Need Professional Attention
Sewer line problems rarely fix themselves. These are the warning signs — from early indicators to urgent situations that need immediate attention.
Multiple slow or backed-up drains
When more than one drain is slow or backing up simultaneously — especially on the lowest floor — the problem is almost certainly in the main sewer line, not individual drains.
Sewage backing up into tubs or drains
Raw sewage coming up through your bathtub drain, floor drain, or lowest toilet is the clearest sign of a complete main line blockage. This is a health hazard — call immediately.
Wet or sunken areas in the yard
A cracked or broken sewer line leaks into the surrounding soil. This creates unusually green grass, soggy ground, or sinkholes in a straight line from your house toward the street.
Sewage smell inside or outside
A persistent sewage odor inside your home or in your yard — especially in the area between the house and the street — indicates your sewer line may be cracked or broken.
Gurgling sounds from multiple fixtures
When you flush a toilet and hear gurgling from a sink or tub, air is being pushed back through a partial blockage in the main line. An early warning sign before a full backup occurs.
Recurring drain clogs throughout the house
If you’re dealing with repeated clogs in multiple fixtures despite professional drain cleaning, the problem is likely a structural issue in the sewer line — not something clearing will permanently fix.
Common Water Quality Problems and What Actually Fixes Each One
Understanding what damaged your sewer line matters — because the cause affects the right repair approach. Here are the most common causes we see in Putnam County homes.
Tree root intrusion
Roots seek moisture and naturally grow toward sewer lines. Once they find a joint or crack, they expand inside the pipe over years — eventually causing complete blockage or structural damage. Very common in Cookeville neighborhoods with mature trees.
Ground shifting and bellied pipe
Tennessee soil conditions cause ground movement over time. When the ground beneath a sewer line shifts, sections of pipe can sag and create a “belly” where waste accumulates instead of flowing freely. A camera inspection shows this immediately.
Offset or separated joints
Ground movement, freeze-thaw cycles, and settling can cause sewer pipe joints to shift out of alignment. Offset joints trap debris, restrict flow, and allow root intrusion at the gap — and are invisible without a camera inspection.
Age and pipe material
Homes built before 1980 in Cookeville often have clay or cast iron sewer lines. These materials deteriorate over decades — clay becomes brittle and cracks, cast iron corrodes. If your home is 40+ years old and has never had a sewer inspection, schedule one.
Grease and buildup accumulation
Years of grease, food debris, and non-flushable wipes accumulate in sewer lines and eventually cause partial or complete blockages. Annual sewer cleaning prevents this from becoming a major repair — especially for older homes.
Flushing non-flushable items
“Flushable” wipes, paper towels, feminine products, and other items do not break down in sewer lines. They accumulate, catch grease and debris, and form blockages that a standard snake often can’t fully clear. Hydro jetting is usually needed.
Sewer Line Repair Methods — What Each One Means for Your Home
Not all sewer line damage requires the same repair. We explain every option honestly — including what each one involves, what it costs relatively, and when each makes the most sense.
Hydro jetting
High-pressure water clears blockages, grease, and root intrusion without excavation. Not a repair for structural damage — but the best way to clean and restore flow in a structurally sound line with buildup or partial root growth.
Best for: Buildup, partial root intrusion, preventive maintenance
Spot repair
When the camera pinpoints a single damaged section — an offset joint, a specific crack, or a section of root intrusion — we excavate only at that point and repair or replace just the damaged section. Targeted and cost-effective.
Best for: Isolated damage in an otherwise sound sewer line
Pipe lining (CIPP)
A resin-saturated liner is inserted into the damaged pipe and cured in place — creating a new pipe inside the old one. Trenchless — minimal digging required. Works for cracks, small collapses, and root intrusion without full excavation.
Best for: Cracks, root intrusion, corroded sections without full collapse
Full line excavation & replacement
When the entire sewer line is deteriorated beyond lining or bursting — severe collapse, multiple failure points, wrong pipe material — full excavation and replacement is the right call. We’ll tell you honestly when this is and isn’t necessary.
Best for: Severely deteriorated lines with multiple failure points
Pipe bursting
A bursting head is pulled through the old pipe, fracturing it outward while simultaneously pulling a new pipe into place. Replaces the full line with minimal surface excavation. Good for severely deteriorated or undersized lines.
Best for: Full line replacement where lining isn’t enough
Pre-purchase inspection
Not a repair — but the most valuable sewer service for home buyers. A camera inspection before closing reveals what the standard home inspection misses. A broken sewer line found before purchase is a negotiating point. After closing it’s your problem.
Best for: Anyone buying a home in Cookeville or Putnam County

Here’s What Our Happy Homeowners Think About Knauss Plumbing
Gas Line FAQ — Cookeville, TN
How much does sewer line repair cost in Cookeville?
Sewer line repair costs vary widely depending on the type of damage, the length of line affected, and the repair method used. Hydro jetting and spot repairs are significantly less expensive than full line replacement. We give you a flat price for each option after the camera inspection — so you can make an informed decision based on what your line actually needs. Call us and describe what you’re experiencing and we can give you a general range before we come out.
What is trenchless sewer repair and is it right for my home?
Trenchless sewer repair refers to methods that repair or replace a sewer line with minimal surface excavation — mainly pipe lining and pipe bursting. Pipe lining installs a new pipe inside the old damaged one. Pipe bursting fractures the old pipe and pulls a new one into place simultaneously. Both require only small access points rather than digging a trench the full length of the line. Whether trenchless is right for your situation depends on what the camera shows — the type of damage, the pipe material, and the condition of the surrounding area all factor in. We assess this and explain your options after the camera inspection.
How often should I have my sewer line cleaned?
For most Cookeville homes, annual sewer line cleaning is a good preventive schedule — especially for homes with large trees in the yard, older clay or cast iron pipes, or a history of frequent clogs. Homes without these risk factors may be fine every two to three years. We’ll give you an honest recommendation based on what the camera shows about your specific line’s condition.
Is a sewer camera inspection worth it when buying a home?
Absolutely — especially for homes built before 1985 in Cookeville. Standard home inspectors do not inspect sewer lines. A broken or root-invaded sewer line is a $5,000–$15,000 repair that is completely invisible to a visual inspection. A camera inspection before closing either gives you peace of mind or gives you a documented problem to negotiate with. We’ve had buyers save many times the inspection cost by finding problems before they owned them.
What should I do if sewage is backing up right now?
Stop using all drains and toilets immediately — every flush pushes more sewage into the backup. Do not try to plunge a toilet when the main line is blocked. Call us at (931) 239-4345 — sewage backup is a same-day priority call. While you wait, stay out of the area where sewage has backed up, as it is a health hazard. If the backup is significant or has reached flooring or walls, call your homeowner’s insurance company as well — sewage backup is often covered.
My yard has a wet spot near the sewer line — what does that mean?
A wet or unusually green area in your yard in a line from your home toward the street is a strong indicator of a leaking sewer line. Sewage leaking into the soil is both a property damage issue and a health hazard. The longer it goes unaddressed, the more soil contamination occurs and the more the surrounding ground softens — which can create sinkholes. Call us and we’ll come out, run a camera, and show you exactly what’s happening.
