Magnesium is a leading anode material given its ability to best protect the steel tank. It “gives up” electrons more freely than aluminum. In some situations where water is more conductive, i.e. softened water or lower pH levels, this sacrificial process is accelerated; in those cases, aluminum is a better choice.
The anode rod in your Bradford White water heater is located at the hot water outlet of your tank. Unfortunately, it is not easily accessible. You must remove the hot water outlet to access it. Some newer Bradford White models have an anode rod which is not located in the hot water outlet, but in a dedicated port for this anode.
If you don’t want to have to check your anode in your Bradford White water heater every year or if you are having some sulfur smell in your hot water, you can install a Corro-Protec powered anode. This powered anode rod stop corrosion, stop the sulfur smell, do not require any maintenance, and is guaranteed for 20 years.
How do you change a anode in a Bradford White water heater?
Can I replace anode rod myself?
