Hi, I’m Brad from Element Plumbing & Gas. Today I will talk about the importance of your hot water heater anode being replaced. I have your best interests at heart and want to ensure you get longevity out of your hot water storage tank.
What is an anode?
An anode is a sacrificial rod of highly active metal that is put in place to prevent a less active material surface from corroding.
In the case of a storage hot water unit, an anode prevents the hot water storage tank from rusting. Your hot water heater anode plays an important part in sustaining the life of your hot water system.
Given that water is stored for extended periods, if your hot water heater anode is not replaced, the steel storage cylinder tank might even split and start leaking.
How do you know when it is time to change the sacrificial anode inside your hot water heater?
The only way to tell is to examine the anode. If the sacrificial rod looks as if it’s being eaten away, it’s probably time to replace it. If you can see the steel core wire showing through the outer layer of aluminium, it’s definitely time for a replacement hot water heater anode.
You may even notice little pieces of foam in your water filters. By this stage, it’s worth giving Element Plumbing & Gas a call to replace your hot water heater anode.
