Perth’s water is hard, some areas seem to be worse than others. So, if you have a storage hot water unit you should check/replace the Anode every few years.
These Anodes protect your tank from corrosion, but once depleted the hard water will start to ATTACK the tank. In my opinion you should get between 12 to 15yr out of a tank but if you replace the Anode regularly these can last up to 20yr.
The pictures show a depleted Anode on the left taken from a hot water unit in Clarkson and a new one on the right.
