Camera Inspection is a small specialized camera attached to a cable that the technician runs through sewer lines. The scope picks up issues before they become problems. With sewer video cameras and locating equipment, no exploratory holes or trenches need to be dug. If you own an older home and have not had your sewer lines scoped before, you should especially get one. Shifting of soil, tree roots, grease build up, deterioration of older type lines and home settling puts pressure on sewer lines.
