This customer in Weaverville, North Carolina, had an old iron filter, and it was time for replacement and upgrade. We tested the water and also found high levels of water hardness. This test result led to a new softener for the hard water issue. An upgraded new iron filter as well. This combo will provide the household with the best water possible. Not only great-tasting water but also this water filtration system protects your plumbing; water heater, refrigerator (ice cube maker), clothes washer, and dishwasher. Happy in Weaverville!
