A modern and efficient water softening system from Scheopner's Water Conditioning eliminates hard water problems. It removes calcium and magnesium from your water supply by filtering it through a resin softening medium. Salt is used to revitalize the system to provide soft water for your daily needs. As stated above, salt is needed to revitalize or clean the resin inside the softener so that it is ready to pull more hardness materials from the water. This salt can be either Sodium Chloride or Potassium Chloride.
Any water softener can use either one.
We prefer to use Sodium Chloride for several reasons. The cost is the main reason. Potassium is usually about 20 cents per pound, compared to Sodium at 7 cents per pound. Some companies will sell Potassium based on health issues. We don't feel that it is a major concern as we usually plumb your home so that the cold water in the kitchen is on hard water for drinking.
