Attached are some pictures of the finished installation of the Terminator and Water Softener System in my house. I want to take the time to mention that everyone that I have dealt with thus far was very knowledgeable and helpful. Sergio spent a lot of time answering questions and working with me thru several phone conversations and emails to figure out a system that would work the best. One of the attached pictures is of the Lakos water filter. I am noticing black material on the screen and was wondering if this is the result of the air contact with the iron? That filter is great!
