• It is wasteful to use hard water in laundry work because a lot of soap is used since soap does not lather easily. This leads to a lot of energy and time wastage.
• It discolourises white garments and also can deposit whitish particles on the coloured garment. This because scum is formed during washing and even when rinsing garments after washes with hard water.
• Water boilers and kettles get discoloured in the inside when used to boil water.
• It causes clogging of pipes. Pipes especially those used to transport hard water get blocked in areas of hard water especially when in long time, mineral salts in the hard water react with the inside of the pipe to form a chemical substance that is deposited on the inside of the pipe. This substance is called scale which appears as a coat inside the pipe. Scale clogs the pipe and so interferes with the water heating system of a building. The water thus takes long to be heated and this way a lot of heat is wasted.
