We had a failing hot water tank and decided to replace it with a tankless unit. We interviewed several plumbers, and we selected 49er Plumbing. The owner, Jeff, demonstrated outstanding knowledge of natural gas tankless technology. He said that he and his employees were factory trained and very experienced with Navien, the unit we selected, and it showed during the installation. Once Jeff and his employees had completed the project, he took the time to answer all of our questions. Jeff's wife, Shannon, who runs their office operation, was a pleasure to work with. Simply put, our experience is that Jeff is an honest, hardworking, highly knowledgable, and reliable plumbing contractor who employs people with his values for top-quality work and excellent customer service. And we are now enjoying endless hot water!
