The tech who came out from Plumbing Express was very thorough. David was his name. I absolutely recommend this company. They are knowledgeable and professional. David was also extremely courteous. Plumbing Express did a significant amount of work when we moved in here many years ago. They replaced all the plumbing and the water heater. I spent eight or nine thousand dollars with them. So when it's related to plumbing, I know who to call. Five stars for Plumbing Express.
