A sewer scope is a video inspection of the lateral sewer line from the house at or near the foundation to the city/HOA tap or septic tank.
The purpose of a sewer scope is to discover visible defects within the pipe, such as root intrusions, cracks/collapse, sag/bellies, offsets, warpage, blistering, blockages, etc.
A full drain replacement can cost upwards of 10 grand! Can you really afford not have your sewer line inspected?
