I have to tell you that the installation of a water softener/filter by ABACUS PLUMBING was one of the best experiences I have ever had with a service company. At our first meeting Jason was professional and knowledgeable in testing the quality of my water and evaluating my needs. My first impression of ABACUS was good. At installation Jason did everything to code and took no shortcuts. His plumbing of the equipment and drains was expertly done. I was very satisfied with the job and will recommend ABACUS to anyone.
