Standard anode rods are sacrificial devices meant to protect tank water heaters from corrosion and failure. Annual maintenance on tanks is typically not carried out resulting in the depletion of the anode rod and corrosion buildup in the tank.
Either replacing an old anode rod with new or replacing with a power anode rod is a great step in doing what you can to prolong the life of a tank water heater.
Master plumber Eric Aune talks about what an anode rod is, how it works and what are some of the options for replacement.
