Why is my hot water orange?

orange rusty hot water

Why you might be experiencing rusty hot water.

Anodes are steel 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.

These rods, also known as ‘sacrificial anodes’, are surrounded by either magnesium, aluminium or zinc. They have been a staple of hot water heaters for decades and are very useful in preventing water tank damage and regular and expensive replacement costs. The rod will corrode instead of the water heater’s exposed steel through a process called electrolysis which occurs when two pieces of submerged metal rod react to a voltage. This protects the water heater from rusting and prevents the water from turning orange.

Getting back to clean, clear hot water

Anodes typically last between 3.5 – 5 years.  Once the anode has fully 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.
