Customer in Hendersonville North Carolina just got an install this morning of our water softener for the hard water issues and a neutralizer , for a low ph water balance. They were experiencing a whitish residue left in the shower,and sinks. Two weeks ago they brought in their sample bottle of water, and the test results indicated a very low pH balance and also hardness in the water. Mountain Water Systems water softeners and all filtration systems we sell are American Made and really are a just a set-it-and-forget-it system. The customers were jubilant with the results after we finish the installation.
