With all of the talk of stinky water and such, let me throw this one out to the folks. Our new home in Kentucky has the hardest water we've ever experienced. Interestingly, the water is delicious but it leaves marks and rings on everything it touches. I don't know if it's coincidental, but the clothes don't get as clean and the dishes coming out of the dishwasher (DW is brand new) aren't as clean as our Joisey home. For those of you who have used hard, hard water, is this your experience? I'm beginning to think a water softener is in our future.
