We run a Kinetico self regenerating, two cylinder water softener. It is approximately 10 years old. We run two 80# bags of Morton System saver salt through our system and then 1 80# bag of rust remover through the system. Our water source is bored deep well 100 FT deep), located out side of a town.
Every 3-4 months we may get a strange oder from the water for a week or two. Our hard water does not have an oder at all. At other times 8-9 months apart, we may get a REAL fine black sand like material from faucet.
