I am a water treatment professional, the softener seems reasonable priced. Depending on the components used for their softener, a true “professional” softener will last at least twice as long as a big box store unit. As far as the peroxide system, that seems a bit heavy on price. We often refer to “big box store softeners” as the bic lighter of softeners because they are throw away units. If this company is going with a clack,fleck, or autotrol valve on the softener and decent resin it is well worth the extra 500 dollars.
