I had a girlfriend like that.

But seriously folks; I've seen a lot of softener systems in my day; wish there was a better way. It's like a machine designed to use up salt and make an income for somebody else.
I used to go up to my brother's house in rockaway, NJ all the time when the kids were little; to fix pinholes in his plumbing copper pipes. They would get tiny tiny pinholes with almost invisible miniture pressurized jets of water. A puddle would appear and then I would locate the leak, drain the pipe, and just torch a little dab of solder on the pinhole and wait for the next one to show up.
That area has really acidic water. The next door neighbors too, pipes always leaking. I've replaced pipes that were literally paper thin! I've heard you can go the pvc pipe route, but also heard that highly acidic water can leach chlorine out of pvc pipe. My brother got all kinds of fancy neutralizer equipment etc. I would never drink the neighbors tap water because I could taste copper in it. They laughed at me when I refused coffee, but I swear that whole family has mental problems; I pointed out they might all have copper poisoning hahahahahha.
I've seen a few houses where the water softener system is plumbed in to the outside spigots, what a total waste of salt. I've seen the salt residue or something white after power washing patio furniture in preparation for repainting at the one place. See that white residue on the cedar steps I just fixed up for the one guy, who has an irrigation sprinkler system.
My brother's ex-wife eventually got a reverse osmosis water filter for the kitchen sink, seems to remove anything harmful.
Even here with the relatively deep well, it seems the water has been getting more mineralized over the years. I get a rusty/mineral buildup on the toilet bowl, have had good results using Zep acidic toilet bowl cleaner. Similar to Lime-Away or CLR. Spritz it in and let it sit overnight- does the trick.
