As long as I’ve had a water softener I never seem to have consistent softwater. Maybe a day or two then it’ll be gone. I do see the salt decreasing...slow, but it does go down. Seems like the only real setting is the hardness setting. I got my water tested for free via mail by a company called aqua science and my water came back saying 6 grains hardness and no iron. I remember calling a plumbing company and he said for our water in San Diego, I should have it set to like 17. Don’t really know too much on how a softener works. Do I need to drain my water heater then regenerate the softener to make sure the heater is filled with softwater? I recently have been seeing what I think is calcium deposits in my toilet, if that means anything.
