Water heater anode rod change frequency
I understand that you are suppose to change your WH anode rod every year under normal circumstances. I learned that lesson the hard way. Ever since, I've put nothing but softened water into my tan...

Water heater is an electrochemical environment.
water, temperature, dissolved oxygen and dissimilar metals.
Anode rod acts s a sacrificial material that dissolves due to galvanic action
Softened water removes calcium and magnesium......minerals that can cause scaling/hard water spots.
But due to the presence of sodium in water from the softener......anode rods can dissolve quicker. Change in water chemistry.
That is why twice a year visual inspection is better than some arbitrary schedule.
