I have a AO Smith KGA-40-916 heater that is about 20 years old.
It has been reliable and I keep it flushed.
We have softened well water and there is never much sediment.
I have not touched the anode rod (I've lived here 13 years).
The anode plug has a raised "U" on the top.
Is that the magnesium or aluminun rod?
What are the consequences of not replacing it (it could be original).
