A sewer line is the buried pipe that carries waste out of your house. When it clogs, cracks or collapses, waste has nowhere to go. It backs up into the drain closest to the floor, often in the basement. Older homes face this more often, because old clay, cast iron and tar-paper pipe wear out.
Priestfeaturing Plumbing is a referral service. We do not repair pipes. We connect St. Louis homeowners with independent providers in our network who handle camera inspections, emergency drain clearing, spot repairs, pipe lining and full replacement. This page walks you through the first steps, the warning signs, the repair choices and the questions to ask. Request a callback to check provider availability, or request an estimate if the problem can wait a little.
Sewage Coming Up? Shut It, Then Breathe
Take a slow breath. The next ten minutes are simple.
- Stop all water use. No flushing, showers, laundry or dishwasher.
- Keep kids and pets away from the wet spot.
- Do not touch sewage with bare hands.
- Open a window if the smell is strong.
Sewage carries germs, so treat it with care.
When to Step Outside
A strong rotten-egg smell, dizziness or a headache means you should leave the room. Go outside for fresh air. If you smell gas like a stove leak, leave the house and contact your gas utility or emergency services.
Signs Your Sewer Line Is Failing
The sewer line is the buried pipe that carries waste from your house to the street main or a septic tank. Watch for these signs:
- Slow drains in more than one spot
- Gurgling when you flush or run water
- Water or waste in the basement floor drain
- A soggy patch or small sinkhole in the yard
- A sewer smell outdoors
- A strip of extra-green grass over the pipe path
One slow sink is often a small clog. Several trouble spots at once point to the main line.
Why the Basement Tells You First
Waste flows downhill. In a house with a full basement, the floor drain sits at the bottom of the plumbing system. When the main line blocks, the mess shows up there first. A sump pump handles groundwater, not sewage, so keep sewage out of the sump pit.
Old Pipes, New Surprises
Frame houses from many decades ago often have old pipe in the ground. Some is clay tile, which cracks at the joints. Some is cast iron, which rusts from the inside. Some is Orangeburg, a pipe made of pressed tar paper. It sags and collapses with age.
Past repairs can hide surprises too. An old patch may use a mismatched pipe. A bungalow or ranch may have had an addition, with a new bath tied into the old line in an odd way. A careful provider checks all of this before giving a quote.
What Damages Sewer Lines
- Tree roots. They slip into tiny joint gaps and grow into thick mats.
- Deep frost. Frozen ground shifts and can crack or pull pipe apart.
- Storms and spring flooding. Soaked soil moves, and heavy rain can overload the system.
- Age. Old pipe wears thin and breaks.
- Wipes and grease. Even wipes sold as flushable can pile up.
- Heavy loads. Driveways and trucks can crush shallow pipe.
Quick Clear or Real Repair?
Emergency drain clearing can get water moving again. A cable or water jet cuts through the blockage. But if roots or a break caused the clog, it will likely come back. Ask the provider if the clearing is a short-term fix. Blocked pipe services give longer-lasting results when the cause is also checked.
How Sewer Problems Are Diagnosed
A provider feeds a small camera on a cable into the line. You can watch the pipe on a screen. The camera shows cracks, roots, breaks and sags. A sag is also called a belly. A locator tool then marks the spot and depth above ground.
Ask to see the video. Ask how deep the problem is and how far it sits from the house.
Sewer Line Repair Options
The right fix depends on what the camera shows.
Spot Repair
A short section is dug up and replaced. It suits one break in an otherwise sound pipe.
Pipe Lining
A resin-soaked sleeve goes inside the old pipe and hardens into a new pipe. It limits digging. It does not suit every pipe, especially badly collapsed ones.
Pipe Bursting
A new pipe is pulled through the old path while the old pipe breaks apart. It needs only small access holes.
Full Replacement
The old line is dug out and new pipe goes in. This is common for collapsed tar-paper pipe or badly damaged clay.
Permits and Property Lines
Many towns require a permit for sewer work and an inspection after. Ask the provider who handles the paperwork.
Also learn who owns which part of the pipe. Often you own the line from the house to the property line, and sometimes to the main. The city may own the rest. Check with your local utility.
Insurance and Paperwork
Some policies may cover sudden damage, but many do not cover wear or roots. Check your policy. Providers can often help document damage for a claim. Take photos before cleanup and keep the camera video.
Questions to Ask the Provider
- Can I see the camera video?
- What caused the problem?
- Which repair options fit my pipe, and why?
- Does the quote include digging, permits and yard cleanup?
- Will the work be inspected?
- Can I get the price in writing?

What's Included
Camera Inspection
A small camera runs through the line so you can see cracks, roots and sags.
Emergency Drain Clearing
Providers can cut through a main line blockage so waste stops backing up.
Spot Repair
One broken section is dug up and replaced when the rest of the pipe is sound.
Pipe Lining
A new pipe is formed inside the old one, with far less digging in your yard.

Questions
Sewer Line Repair FAQ
How do I know if my sewer line is broken or just clogged?
A clog in one drain is usually local. If several drains are slow, the basement floor drain backs up, or the yard is wet, the main line may be blocked or broken. A camera inspection shows the real cause.
Can I use my toilet if the sewer line is backing up?
No. Stop using all water in the house. Flushing or running a sink sends more waste into a blocked line, and it can come up in the drain closest to the floor. Wait until a provider checks the pipe and clears it.
Does homeowners insurance cover sewer line repair?
Some policies may cover sudden damage, but many exclude wear, age and roots. Sewer backup coverage is often a separate add-on. Check your policy and ask your insurer. Providers can often help document damage for a claim.
