I've been using Benjamin Franklin Plumbing of Duncanville for a few years now, and recently needed their help with a toilet that was running. The plumber they sent found out he needed to replace all of the parts from the inside of the tank. He was very thorough and diligent; he did a good job. Benjamin Franklin Plumbing has always been knowledgeable, and do a great job of explaining everything to me. They always leave things clean before they leave. I will call them again if I have any further plumbing issues.
