I was having some foundation problems, and the person who was out here recommended I use Benjamin Franklin Plumbing of Tyler, Texas. I live pretty far away, but setting up the appointment was easy, and their tech, Clint, was very good. He came out to do a hydrostatic test on my plumbing and said everything was OK. He was courteous, polite, knowledgeable, and he knew what he was doing because he did it well. It was kind of expensive because of the distance, but I would consider using them again.
