No I had no idea. Only time I've lived in a place with really hard water was when I was just a wee thing. For the past 25 or so years every where I've lived has either had soft, or medium water. Never had to mess with a softner.
I'd say it can be quite the pain. Nothing more than spinning your wheels and going no where fast.
Twisted- do you have the testing kits so you can test you water so we know more what your working with?
Wayne- Since the traditional methods of testing are not going to be accurate, is there any other way to tell about how hard or soft the water really is? Will the softener flub both the gh and kh tests, or just one of them?
