Hardness in your water supply is a result of water absorbing calcium and magnesium from limestone, marble and chalk deposits. The minerals contained in hard water settle out as a deposit of hardness scale, wherever the water is heated or when cold standing water evaporates. Examples of this include; white marks, stains and scale on sinks, baths, toilet bowls and around the base of taps, blocked showerheads, scale deposits on kettles.

Water hardness creates soap curd, which interferes with the ability of your cleaning products and causes problems such as bathtub ring. Hard water also causes scaling in your water heater and can clog pipes, fixtures and all water using appliances
