Water hardness
Water hardness refers to the concentration of calcium and magnesium salts in the water.
User manuals for new appliances, such as dishwashers, sometimes recommend that you check water hardness levels in your water supply before connecting the appliance.
The Australian Drinking Water Guidelines recommend that a 'good' level of hardness (measured as calcium carbonate – CaCO3) is less than 200mg/L.
The below table shows average water hardness levels as at 4 December, 2017
