I'm glad I asked the question about water because I have read so many diverse opinions. Now we are talking about limescale, which is all part of the water problem.
here in Spain where I live we have terrible water, at first we were told it was ok to drink but after someone decided to get it tested we reverted to water from a spring in a village nearby which is straight from the mountain.
However we still get limescale especially in the kettle and we have tried everything including putting a cork in the kettle which is supposed to collect the limescale.
On our water inlet pipe we have an electronic Scalemaster which is supposed to keep particles in suspended state, we also have a water filter which is horrifying when you see just how much dirt and muck is in the water.
So does anybody have an answer to a maiden's prayer (!!!) how can we make sure that we have clean water.
Will also add that we have boiled bottled water and got the same furring in the kettle although it did take longer,
