The higher the content of these minerals and salts, the harder your water is. Water
hardness is measured in equivalent scales, Clarke degrees, French degrees (°TH) and
mmol/l (millimol per litre - international unit for the hardness of water).
The softener should be adjusted according to the hardness of the water in your
area. Your local Water Authority can advise you on the hardness of the water in
your area.
