Groundwater gets colder in the fall and winter, meaning your water heater has to work harder and longer to reach the same output.
An anode rod acts as a "sacrificial bodyguard" for your water heater.
Key Functions
• Attracts Corrosion: Pulls corrosive elements, minerals, and free ions away from the tank's interior lining.
• Sacrifices Itself: Rusted and eaten away over time instead of letting the steel walls or welds weaken.
• Extends Lifespan: Can stretch a water heater's life from 8–12 years up to 15+ years when replaced regularly.
