A belly holds waste and water. We measure the sag and choose between lining and replacement.

- ResultA fix built to last
A belly, or sag, is a low spot where the pipe has settled. Water and waste pool there instead of flowing, leaving solids to build up, odors to develop and clogs to return. A camera shows standing water in the pipe and a level check shows the depth. The fix depends on how deep the sag is: shallow ones can sometimes be lined, deeper ones need the pipe corrected with replacement.
We run a camera and use locating and level tools to measure the sag. For minor sags with good pipe, lining or cleaning can restore adequate flow. For larger bellies, trenchless replacement along a corrected grade is more effective. We explain the difference and why a liner cannot lift a sagging pipe.

Sagging Sewer Line Repair: answers
Can lining fix a belly?
A liner follows the pipe, so a deep belly remains. Small sags may be acceptable, and the measurements decide.
How deep is too deep?
When water stands deep enough to hold solids, correction is advised. We explain with your video.
Will a new pipe fix it?
Yes, if the new line is laid on a proper grade.
Can I live with a belly?
Many people do for a while, with periodic cleaning, but it often gets worse.
