I bought my house 18 months ago. There was a water softener unit (GE brand). Turns out it hasn't been working for a bit and I have noticed more hard water stains on my dishes. Well the estimate I got was $450 to fix it and it looks like new ones are around $4-500. So I'm obviously not going to get it fixed. But my question is should I replace it or not? Pretty much everyone I know around here has one so I guess the city water is pretty hard. Can I just get a softner for the kitchen and not get a whole house unit? Anyone have any experience with this?
