You kid, but it gets really frustrating when consumer goods die after two months because your tap water is pretty much liquid chalk. Pour a glass, leave it for an hour, there'll be a few mm of calcium carbonate precipitated out in the bottom of your glass. Can't use it for ice (just crumbles - too mineralised), coffee and tea end up with a skin, anything that quick-boils water, like an espresso machine, is destined for the trash heap.
