My water is from a 100 foot well drilled 40 years ago. A multitude of
tests over that time is 36 to 60 grains hardness. Presently with 2 in
the house and the whole house connected through both an iron filter
and water softener I use 50 pounds of salt in 2 weeks and regen every
3rd day. I can smell, taste, feel, and also see a lack of soapsuds,
all of which proclaim that the water needs regeneration.
