Rusty hot water? Is your hot water orange? Does it taste like rust or metal?

Orange hot water? Does your hot water look rusty or taste like metal?

We received a call from a Beacon Hill customer (Northern Beaches Sydney) whose hot water heater had burst. Water was spilling from the top of the tank, causing them concern about damage to their property. They said that their hot water had been orange in colour and had a metallic small for some time.  Immediately, we knew what had happened.

John arranged to visit the customer later that morning, to assess and rectify the problem.  Over the phone, he instructed the customer how to turn off the water supply to the hot water tank which stopped more water from filling the tank and flooding the area further.

Once onsite, it became obvious to John that the customer’s hot water heater was seriously corroded.  He explained to the customer that, due to its age, it was beyond economical repair and needed to be replaced. The customer understood.

John disconnected and drained the old hot water system.  As the photo above shows, the water was very rusty and orange in colour – a sign of significant corrosion of the tank. It definately had a very strong metallic smell.  It would have tasted awful if accidently drunk.

If you notice orange hot water or that your hot water has a metal smell or metallic taste, contact us immediately for advice.  It is a sign of a larger problem with your hot water system that needs to be fixed ASAP. It won’t fix itself.

Why is my hot water orange?

Once the inside the internal tank of your water heater starts to rust and corrode the hot water turns orange. To prevent and deter this, some hot water systems have anodes are installed inside. These steel core 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.

Some anodes only last between 3.5 – 5 years and need to be replaced to prevent corrosion.

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 on 0410 693 532 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 an assessment.
