Adele ring. In mathematics, the adele ring (also adelic ring or ring of adeles) is defined in class field theory, a branch of algebraic number theory. It allows one to elegantly describe the Artin reciprocity law. The adele ring is a self-dual topological ring, which is built on a global field.
Real softeners generally last 20+ years EVEN on ludicrously hard water while the service life on a pre-built softener seems to be under 5 years (if you're lucky) on really hard water and lasting longer than that is a rare exception.
Most good softeners today, recharge based on how many gallons of water you use, and how hard your water is to start with. However, most of our customers today are adding salt once or twice a year, on average. Unfortunately, no. A water softener is designed to remove hardness (calcium and magnesium) from water.
