You read about both and it sounds like why am I carrying those bags of salt?
Be careful do your research completely and do not stop at what you want to hear, first let’s explain how they work.
A softener that uses salt has an ion exchange process, this means as the water passes through the resin one calcium ion is exchanged for one sodium. The calcium sticks to the resin bead and does not enter your plumbing coming into your house. When the resin beads are coated in calcium and can no longer hold any more calcium the unit goes into regeneration. This is when the unit pulls the brine water into the water softener, the brine water makes it to where the calcium lets go of the resin bead and is washed down the drain beside the softener to where only soft water has come into your house.
Usually a water softener will bring 20 grains per gallon the average in San Antonio down to a 1 or less per grain entering your house. Only soft water water enters into your house. During regeneration the resin beads are cleaned and should be able to go about a week before this process happens again usually in the middle of the night around 2 A.M.
