A sewer scope is a service that is designed to check the condition of a sewer system and tell if it is functioning as designed. This process has become a standard component of the pre-purchase inspection for properties.
In this process, a technician inserts a miniature video camera into a sewer through the sewer cleanout, checking for root intrusion, holes, pooling, cracks and pipe separation. A sewer may have one of these problems and still be functioning, as not all of these affect performance. So this process is not only useful for determining the functionality of a sewer, but also serves in preventing unexpected emergencies in the future.
