The difference between the WATERBOY System and a salt-based system is that the WATERBOY system does not require any salt or chemicals. The disadvantage of a salt or potassium water softening system is that it addresses only one problem, and that is the hardness of the water. It does not filter the water. Salt based systems remove calcium and magnesium minerals and exchange them for sodium chloride or potassium chloride. The result is that there is salt throughout the house, which you have to shower or bathe in, as well as the additives the city puts in the water. Drinking the salt water is not recommended, so a reverse osmosis unit is usually installed to remove the salt. A salt system requires lugging bags of salt or potassium and/or having an exchange unit that requires service people to enter your property on a regular basis.
Another disadvantage that we hear from our customers, who have had salt systems, is that they have to replace their hot water tank every 3-5 years, due to corrosion. In addition, most softeners are being banned throughout California due to environmental issues. A water softener has to use salt to “regenerate” or flush out the built-up minerals in the resin tank sending high content sodium levels down the drain.
