Where do you think salt comes from? Outer space?
Ours comes from evaporation plants around the Great Salt Lake, and when it gets flushed through our softener systems, it drains back to...Great Salt Lake.
Yes but first, it go's through your septic system if you have one, and it screws up your concrete septic tank and concrete distribution box. So if one must use salt it is best to have poly tank and box, otherwise expect to replace both tank and box as the salt destroys them pretty quick.
