Corrosion
The most common driver of accelerated anode consumption is elevated electrical conductivity in the water, not the mere presence of sodium ions (or the absence of Calcium). I have been solving corrosion problems for three decades, from…

Ion exchange trades calcium and magnesium for sodium (or potassium) on an equivalent basis. The resin does not know or care whether the water started at 5 or 55 grains per gallon. It swaps one equivalent of hardness for one equivalent of…
