When several drains back up at once, or sewage comes up in the lowest shower or floor drain, the problem is usually in the main sewer line between the house and the street. In Las Vegas that line is often ABS or PVC, and failures come from root intrusion near trees, offset joints, sagging sections in shifting caliche soil and damage from past construction.
Our sewer line service starts with clearing the line and running a video camera from the cleanout. We record the footage, locate the problem from the surface and mark its depth, so you know exactly where the damage is and what it will take to fix it before any digging begins.
