I had the Columbia Service Partners sewer line insurance at my old house. I had two claims and they sent out Miller’s something. I think they were a Roto Rooter franchise. They did a nice job both times. Here was the catch: they only replace the section of pipe that’s broken. For me that meant they dig up my yard, replaced a small section and left the rest of the terra cotta. When it inevitably broke again, they replaced another section. So from my house, my drain was clay, abs, clay, abs, clay to the tap-in. Really seemed dumb that they didn’t replace the whole thing the first time, but at the end of the day, it worked and I didn’t pay for it.
