Anode rods protect the water heater tank from the destructive effects of water over the years.
A bad smell may mean that the rod needs replacement. Sometimes the water filtration system will destroy the anode rod very fast and should be replaced as soon as one year.

- Many water heaters have anode rods of metals that will permit the water to attack that metal instead of the steel tank. (Some heaters do not have any rods to replace! If there IS one you will see a 1-1/8" nut under a piece of opaque plastic at the top of the tank)
-
- Called SACRIFICIAL ANODE RODS, these are made of metals such as Magnesium or Aluminum and removing these and replacing them is a real nice way to extend the life of the heater but use extreme caution because you may:
- Break or stress the piping; DON'T MOVE THE TANK WHEN EXTRACTING THE OLD ROD.
- Experience a shock; SHUT OFF THE POWER AND CONFIRM THIS WITH AN ELECTRICAL METER.
- Cause a electrical problem; BE CAREFUL THAT THE ELEMENTS IN THE TANK ARE NOT DISTURBED AND THAT WATER DOES NOT GET INTO THE CONNECTIONS.
- Cause a flood. CONFIRM THE WATER IS COMPLETELY SHUT OFF.
