HARD Water is simply a reference that water contains elevated concentrations of dissolved minerals predominantly as Calcium and Magnesium.  It should be noted that both of these minerals are naturally occurring and are effectively harmless.  These minerals are rather the vermin of water and make it very inconvenient for us humans by scaling of our domestic appliances, leaving spots and streaks on our fixtures and fittings.

The degree of hardness of the water increases, when more calcium and magnesium dissolves and water above 120ppm is considered to be hard.  The hardness in Perth’s scheme water ranges between 180 to 300 ppm, so yes we have hard water, but remember its just a nuisance (so they say).

There are some applications that these minerals actually causes issues such as:

  • Dry hair & skin
  • Scaled hot water elements require more power to heat water
  • Clogged evaporative air conditioner panels reduce cooling
  • Corrosion to pipes and fittings
