Should I repair or replace my sewer line?

Let the camera decide. A collapse or break means replacing that run. A clear line after one backup means cleaning. Roots or an offset joint can be a spot repair or a liner, depending on how many there are.

Do I need a camera inspection first?

Yes, for any decision beyond one cleaning. Ask for the recording and a written list of findings by distance, so a second company can bid on the same list.

What do I do if sewage is backing up now?

Stop using all water in the house and keep people and pets away. Call a plumber who handles sewage backups, and your insurer if it reached living space.

Is lining the same as replacing?

Lining puts a new pipe inside the old one without a trench. It follows the old shape, so a sag stays. Ask how any method handles each finding on the footage.

Does an old sewer line need replacing?

Not because of age alone. Clay, cast iron and other materials fail in different ways. The camera shows the condition; the year does not.

What is the 50% rule?

A rule of thumb: if a repair costs half or more of replacing the run, replacing can make more sense. It is one input, not a standard.

Sewer line: repair or replace?

Pick what the camera showed and how often the line has backed up, then type the two bids. Nothing is stored or emailed.

Camera first before anyone prices a new sewer The finding decides the method: a clear line after one backup is a cleaning; a collapsed section is a replacement of that run. Ask for the footage.

Replace a sewer line where the camera shows a collapse, a break or defects along the run; clean and watch where it shows a clear line after one backup. Roots at a joint lean repair with a plan. Repeated backups and a repair costing half a replacement lean replace.

Work out repair or replace

A check on a camera report and two bids, not a diagnosis of your line.

If sewage is backing up now

Stop using water. Every sink, toilet, shower, dishwasher and washer adds to it. Keep people and pets away from the sewage.

Then call a plumber who handles sewage backups, and your insurer if it reached living space. This page is for the decision after the backup is cleared.

Worked examples

Three camera reports, run through the tool

Clear camera, one backup

Lean clean and watch. A blockage was cleared; the pipe is sound. Note the date.

Roots at a joint

A $400 cleaning against an $8,000 replacement: lean repair with a plan. Clear the roots, then repair or line that joint.

Offset joint, repeated backups

A $3,000 spot repair against a $5,000 replacement is 60%: lean replace for that run.

The bids are examples; type yours. 50% is a rule of thumb, not a standard.

What each camera finding shows, and what it does not

Ask for the footage and a written list of findings by distance from the cleanout.

Finding	What it shows	What it does not show
Clear line	The backup was a blockage that has been cleared	That it will never recur
Grease or soft blockage	The line needs cleaning; something may be helping waste collect	A broken pipe
Roots at a joint	An opening at that joint that roots can return through	That the whole line is failing
Scale in cast iron	The bore is narrowing; the camera shows how much	That it will fail soon
Offset joint	Something moved; a defect at a known distance	That the whole run is bad
Belly (a sag holding water)	The pipe has lost its slope over a section	How urgent it is: ask how the method fixes it
Crack, break or missing section	A structural failure at that point	How far the replacement should extend

What each repair method can and cannot fix

Each method answers a different finding. Match the method to the footage.

Cleaning: cable, cutter or water jet

Clears blockages, roots and grease in a sound pipe.

Cannot: close the opening roots came through or fix a sag.

Spot repair

Digs at one known distance and replaces that section. Fits a single break or offset.

Cannot: fix defects spread along the run.

Lining or pipe bursting

Trenchless: a cured liner inside the old pipe, or a new pipe pulled through it. Avoids a full trench.

Cannot: a liner follows the old shape, so a sag stays. Ask how the method handles any belly on the footage.

Open-cut replacement

Digs the run and lays new pipe on new bedding, which restores slope and alignment.

Adds: restoring the driveway, lawn or street. Ask for it as its own line.

Who owns which part of the sewer line

It is set locally. The line from your house to the public sewer can be split between you and the city at the property line, the cleanout or the main. Ask your public works department.

Before you price a street-side section, confirm it is yours, and whether the city needs a permit for work in the right of way.

On a septic system, the tank and drain field are a separate job from the pipe that feeds them.

What a sewer bid should state

The camera findings by distance
With the footage, so a second company can bid on the same list.
Which sections are priced, and where the work stops
Your side only, or into the street.
The method, and how it handles any belly
By distance on the footage.
Restoration of what is dug up
Driveway, lawn, planting or street surface, itemized.
Permit and inspection
Who pulls it, and whether the city inspects the connection.
A camera after the work
So you can see the finished line.
“It’s shot” with no footage
A verdict without a recording is not a finding.
