We have a sensitive clay main line and carry sewer insurance because we know that there will be annual back-ups and eventually a serious break. Our sewer insurance sent Quality First Plumbing to clear the line and our plumber, Kris Grimes, did an amazing job of clearing the line efficiently. Because of our insurance, I have no idea how much the service would have cost out of my pocket, but Kris was worth every penny. In 14 years of life with our special main line, Kris has been the most complete, thorough, and knowledgeable person who's cleared it.
