I recently discovered a dip in the line or "belly" of my sewer line which is in the slab of my house. The house is 5 years old. I've had a plumber run a snake and twice they have confirmed I have about 3 or 4 dips. I've owned this house for 3 years and the previous owner had the same problem. I found this out from the neighbors. This was not disclosed in my closing. I discovered the problem once my toilet backed up into my tub. Do I have any options on who is responsible for paying for repairs? The original plumber is coming to inspect his work and has admitted he originally fixed the same problem 4 years ago but he seems to think, with out looking, that there are other dips now. One the seller should have disclosed this information (Arkansas is the State this is in). Second the plumber should also be responsible. These are my thoughts. Anyone have any suggestions on what I can do to get help pay for the repairs? Or do you have any suggestion on what I should do besides sucking up and paying it all myself? I assume this will end up costing 10 to 20 thousand, which would include cosmetic repairs after the dips are fixed.
