Hardness is calcium and magnesium, which a softener removes and they
also remove ferrous iron, manganese, lead, copper, radium etc.. All
positive changed ions.
Scoot, this build up can be caused by a number of things that a
softener does not remove. Like high TDS (total dissolved solids),
sulfates, chlorides, sodium etc.. But not "sulfur". I think the guy
probably said sulfate or sulfates and you heard "sulfur". Most of
those things are negative charged ions and you would use an anion
resin in a softener regenerated with softener salt to remove them.
That can be expensive and the TDS will not be reduced or removed.
Water is either soft, meaning 0 gpg of hardness (in industry it is
measured in ppm or mg/l and it takes 17.1 of them to make 1 gpg) or
the water is hard, meaning there is 1 or more gpg of hardness in the
water.
Alkalinity is not removed by a softener, nor is the pH changed by ion
exchange softening. The TDS may be increased slightly depending on the
amount of ion exchange that is done.
