Because our plumbing has stopped up numerous times we had a camera video made. The last time it stopped up I ran the washer and sewer came up through toilet and flooded the bathroom. What a mess! It shows no breaks but a significant belly. Our sewer line is under the slab and the estimate to repair is $11,500. Since there are no breaks do we need to spend this kind of money to fix or just have the sewer line cleaned each time it stops up. The house was built in the mid 1960s. Do you think this is a reasonable price. The tunneling will be approximately 20 feet under the house and then a line ran to the side clean out that connects to the sewer line. About 80 to 90 ft.
