These issues do not adversely affect the taste and odour of water. In fact most people prefer the taste of hard water. Water is 'hard' because it contains calcium &, perhaps, a little magnesium both of which, we are told, are good for us.
For potable use, medical and other expert bodies favour hard water over soft water and over 'softened' water in particular because of the added sodium. It is irritating to de-scale a kettle but a lot of people use denture cleaning tablets overnight and even vinegar(a bit slow) to good effect. The biggest problems with hard water are caused by limescale in your pipework, tanks, valves, cysterns, kitchen equipment and, especially, your hot water system.
We suggest you consider either a Whole House Ion Exchange System (aka Salt Softener, Base Exchange) or an electronic solution - we do not sell either.. Unlike drinking water filters, for an ion / base exchange salt softener we urge you to buy locally at a good DIY store, ironmongers or plumbers ... more.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
