I really appreciate the team at Water Group 7. They have been great about contacting me and following up, answering all of my questions with patience and honesty. They came for a free consultation, were upfront with everything, and I have never felt pushed to purchase any of their products. I have only had this filter for 1 day, but it seems to be working well. There are no signs of cloudiness in the water after the initial flushing. I have no doubt that should a problem ever occur, I could depend on them to fix it.
