We moved to a home in Edina that had an old, inefficient Surge water softener. It would run for hours, and it used so much salt. We wanted a more complete system that would give us clean water, and also something that was not so wasteful. We love the DMT and Reverse Osmosis system. Our rust and sediment problems are gone. The water tastes great – the entire system works very well. I highly recommend you to others.
