A sewer backup is a disgusting and expensive event that can be costly when you own a home. Sewer line repair can also be extremely expensive, as it can require excavation and potentially foundation/street/sidewalk repairs. A sewer camera inspection before you purchase the home will help ensure that the main sewer line is free of problems that can cause headaches after you move in. The inspector inserts a flexible rod with a specialized high-resolution camera, up to 100 feet into your main sewer line. Real-time image transmission allows the inspector to determine the condition of the inside of the pipe and understand any existing or potential problems.
