Find my pathAbout this term
In many jurisdictions, the homeowner is responsible for maintaining the sewer line from the house to the city connection point, while the city is responsible for the main line. Sewer line problems can include blockages, root intrusion, or collapse. A sewer line inspection using a camera can identify problems. Some sellers offer sewer line warranties or the buyer may negotiate credit for potential issues.
Pro Tip
If on municipal sewer, ask the city about sewer line history. Frequent breaks indicate aging infrastructure.
Example
A home inspection reveals potential sewer line issues; the buyer negotiates for the seller to pay for a sewer line camera inspection, which confirms there is root intrusion, and the seller agrees to pay for root removal.
