as smelly water and removal of the rod will void any warranties stated or implied. However, this

The anode rode is a sacrificial metal rod that avoid corrosion and premature failure (leaks) in the tank. It is a consumable item. Inspect the anode rod after the first six months of operation when you drain and flush the tank. Replace the anode rod if it’s substantially worn out or has depleted. Thereafter, inspect the anode rod annually or more frequently if needed. If you use a water softener, your anode rod will deplete faster than normal and as such would need more frequent inspection.
Once the anode rod has been depleted, it will need to be replaced. Please consult the “Parts” section to see the Spare Parts code and contact your plumbing supplier to obtain it. (Anode rods are a consumable item and are not covered under warranty).Certain water conditions will cause a reaction between this rod and the water heater, potentially causing smelly water. The parts list includes a special anode for such cases in which the water has a different odor or discoloration due to this reaction. A water conditioning company might have to be contacted to supply filtration equipment if the issue persists.
Failure to inspect the anode rode at least once a year could cause the tank to fail and leak. This condition is not covered under the manufacturer warranty.
