I had no idea how bad hard water could get until I moved to London.

I get limescale on everything. I descale my kettle every week or two (almost daily if not using a Brita filter), shower head monthly. I pour citric acid down the toilet weekly. My taps actually form little calcium stalactites over a few months. Thermostatic shower cartridges are an annual replacement item because the limescale gets them too.

I keep demineralised water around for sensitive equipment like humidifiers.

On the bright side, I love how hard water tastes.
