Trenchless Pipe Repair in Greenville, TX: Can a Camera Inspection Save Your Yard?
A camera has found a crack or roots in your sewer line, and the repair quote involves a trench across the yard and the driveway. Lining the pipe from the inside is sometimes an alternative, but only for some pipes. This page shows what the camera has to show, how the methods compare and what to ask before you choose.
Does your pipe qualify? What the camera has to show
A liner needs a pipe that is still roughly in line and holds its shape. Ask the plumber to show you the footage and say which of these your pipe falls into.
Usually a good fit
- Cracks and small holes
- Roots entering at joints
- Leaking joints
- Rough or scaled walls on a pipe that is still straight
Usually a poor fit
- A collapsed section
- A joint pushed far out of line
- A sag that holds water
- A pipe that has lost its shape
A sag, which plumbers call a belly, matters most. A liner follows the shape of the old pipe, so it will hold the same pool of water. Ask directly whether the camera shows a belly and how deep it is.
Lining, pipe bursting or digging: how the three compare
Each method suits a different problem. This is how they compare, and none of them is better in every case.
| Method | How it works | What it disturbs | Best when |
|---|---|---|---|
| Lining | A resin-soaked liner is pulled into the old pipe and cured, forming a new pipe inside it. | Small access pits at each end. | A pipe that is intact enough to hold a liner. |
| Pipe bursting | New pipe is pulled through as a tool breaks the old pipe outward. | An entry pit and an exit pit. | A line that cannot be lined but can be replaced along its path. |
| Open trench | The yard is opened along the line and the pipe is replaced. | The widest: lawn, plants, sometimes a driveway or slab. | A collapse, a belly or a joint far out of line. |
The excavation route is covered on the page about traditional sewer line excavation, including collapses and offsets.
The day of the repair
- The plumber locates the access points and has utilities marked before any digging, even for small pits.
- The pipe is cleaned, often by jetting, and a camera confirms the condition.
- The liner is placed and cured, and the plumber reopens the branch connections.
- A final camera pass shows the new surface and the connections.
- The pits are filled and the surface is restored. Ask who restores it.
Ask for the finishing footage. It is your proof that the liner is smooth, the connections are open and the ends are sealed.
Questions that separate a good quote from a vague one
A vague trenchless quote hides the details that decide whether the repair lasts. Ask each plumber for these:
- Where the liner starts and ends, and what part of the line is left unlined.
- What the liner is made of and how it is cured. The plumber should be able to explain it in plain words.
- Whether the pipe gets smaller. A liner reduces the inside diameter slightly, so ask whether it affects flow.
- How branch connections are reopened and checked.
- What happens if the camera finds a belly. The quote should say so before work begins.
- The finishing footage and a written summary.
- Warranty terms in writing, from the plumber, covering the liner and the labor.
Access pits, permits and where your line ends
Even small access pits mean digging, so Texas811 applies: call at least two business days ahead, homeowners included. See Texas811 for how the call works.
The city's permit pages list plumbing as a permit type in general and say nothing specific about lining a sewer line. Ask the plumber whether a permit applies, and check with the Permits and Inspections office at (903) 457-3100 if you want it confirmed. Under the city's sewer code, a direct connection to the public sewer is at the owner's expense, so ask the plumber to mark where your line ends and the city's begins, and put that in writing.
Rule out a plain blockage before you commit to lining
A backup does not always mean a damaged pipe. A grease plug or a wad of wipes can back up a sound line, and clearing it costs the homeowner far less disruption than any repair. Before you commit to lining, ask whether the camera found damage or only a blockage, and whether the line was cleaned before it was recorded.
Footage taken through a partly blocked pipe can hide the true condition of the wall. Ask for a second look after the line has been cleaned. If it comes back clean, you may not need a repair yet. If it shows cracks or roots in the cleaned pipe, you have a stronger case for lining, and a clearer footage record to compare quotes against.
Living in the house while the line is lined
Lining takes the sewer line out of service while the work is done. Ask the plumber how long that is expected to last and what you can use meanwhile. Toilets, showers and washing machines all drain to that line, so plan around the answer.
Ask where the plumber will stage equipment and whether a truck will block your driveway or the street. Move cars, and mark sprinkler heads and any buried lines you know about before the pits are dug.
The limits of lining, and where else the idea applies
Lining stops roots from entering at the repaired joints. It does not remove a tree, and roots can try other places, so ask what maintenance the plumber expects. If the pipe was clogged before lining, jetting the line clean first is part of the job. If clogs are what brought you here, a recurring clog is worth reading before you commit to a repair.
The same idea is sometimes used under a floor slab, where a plumber routes new pipe without opening the floor. That case, with its own cautions, is covered under slab leak repair options.
