Can a water softener cause anode rods to corrode?

When sodium is added to the water (such as when a water softener is used), anode rods can corrode more quickly. Water softeners can help reduce scale build-up and sediment, but anodes can corrode in as little as six months if the water is over-softened.

How long does an anode rod last on a water heater?

The anode rod is “self-sacrificing” and will continue to corrode until eventually it must be replaced. When there’s no sacrificial metal left on the anode, the tank can rust out. Anode rods generally last about five years but it really depends mostly on the quality of your water and how much water travels through your water heater.
