Advantages of hard water
• It provides useful calcium ions for healthy growth of teeth and bones.
• It tastes better and is thought to reduce the number of heart illnesses.
• The formation of lime scale in pipes causes the inside of the pipes to be covered with insoluble carbonates.
• This layer of carbonate prevents the water in the pipe
from coming into contact with the metal of the pipe
and so prevents pipe corrosion
and poisonous metal salts becoming dissolved in the water
