Question

hard water is the necessary evil

Answer 1

The water running to your home is used every day, several times a day. Running the dishwasher, the washing machine, showering, cooking, and cleaning all require a constant supply of clean, safe water. As hard as your water works, did you know that hard water doesn’t actually work, well, as hard?
In fact, hard water can actually stain clothes and dishes that were cleaner when you started washing them.
