I purchased a US Water System for my home after submitting required water testing results required to custom fit our needs. I was assured in writing and on many phone calls our water issues would be resolved with this system. I hired professional installers not trusting ourselves despite their claim it s easy diy for homeowners because I wanted everything to go perfectly. I trusted the system would do as the sales man promised and resolve our water issues so I replace my homes 4 baths toilets and hardware. The system did nothing, remove no iron or tannins and I was left with severe staining and all brand new fixtures. The company refused to return the product even after I did further testing in with patient for a resolution.
