The minerals contained in the hard water settle out as an unsightly deposit of hardness scale whenever the water is heated, or when cold standing water evaporates.
Examples of this are:
• Unsightly white marks, stains and scale deposits
• Scale deposits leading to premature failures of water heating elements
• Clogging of pipe work
• Water hardness also makes it difficult to get a good lather; so much more detergent is required for washing. Hard water increases detergent requirement by 50% and creates soap scum.
• Dishes and glasses look dull or smeared even after washing.
