看来是需要换这个ANODE
“Why is my hot water orange?”
If the water coming out of the hot water taps is discoloured, usually orange, then it could be due to a spent anode inside the hot water heater. It may also have a metallic smell about it.
First, to determine whether the problem lies with your HWS, test the colour of the cold water supply too. If the cold water is orange too then this could be a problem with your water supply and you should contact Sydney Water (or your water supply company) or you might have an old galvanised steel water pipe between the meter and building, which is rusting internally.
If only your hot water is orange (or a rust colour) then it is a sign that the sacrificial anode inside your tank is spent, reaching the end of it’s useful life inside your tank. Anodes are magnesium core rods installed at the top of the hot water tanks during production to prevent rust and corrosion. Once the inside of your water heater starts to rust and corrode your hot water turns orange.

RECOMMENDED SOLUTIONS IF YOUR HOT WATER IS ORANGE
Anodes typically last between 3.5 – 5 years. Once the anode is spent it fails to protect the tank which will start to deteriorate. In time, a rusting water heater will cause problems which are typically more expensive to repair than simply replacing the anode. Regular anode replacement ensures your water heater continues to operate as intended and lasts longer therefore saving you money in the long term. If your water heater is over 3.5 years old, we suggest you contact us and we can advise whether your anode may require replacement. If you supply us with the make and model of your water heater we will be able to determine whether a service call is required. Some anodes last longer than others, depending upon the material of which they are made, so a quick phone call will give us the information we need to make such as assessment. |
