DFW Pipe & Plumbing is just an excellent company. I called them almost on the spur of the moment and they were very responsive. They came out to test for leaks and they were very thorough. They did a complete isolation test as well. They even went up onto the roof to test for leaks. The young technician who came was so knowledgeable about plumbing in terms of how everything worked. It was a good experience and I was happy with the service they provided.
