Forum Title: Strange Water Heater Anode look.
Only by an accident I've learned about anode existing in water heaters. Since my heater sits (and still works) somewhat about twenty (20) years (despite nine (9) years warranty), I've decided to change the Anode. I found all necessary info on the internet. However, my old Anode has quite different look, unlike any described in available sources: the water never smelled bad or had any discoloration, but the Anode has a DARK BROWN build-up all over its entire length, and under this layer of buid-up, there remains INTACT Anode , unlike those shown in available sources. The year of production of the tank is 1996, yes, it is 20 years already and all time is ON, never was shut-off. I have a question: what is wrong with my Anode / heater / water? Why this strange build-up, instead regular weared Anode?

To each their own but if I had a water heater that lasted 20 years I wouldn't touch a single thing in it or on it let it do its thing but hey that's me

The anode is most likely passivated. The brown buildup, is it a solid or slimy? Iron bacteria most likely. Well water?

Nothing is wrong. You are blessed with good water that has not eaten away the metal of your water heater. Rejoice!
