In each water heater there is installed at least one anode rod see parts sections for corrosion protection of the tank Certain water conditions will cause a reaction between this rod and the water The most common complaint associated with the anode rod is one of a rotten egg smell in the hot water This odor is derived from hydrogen sulfide gas dissolved in the water The smell is the result of four factors which must all be present forthe odor to develop A Aconcentration of sulfate in the supply water B Little or no dissolved oxygen in the water Asulfate reducing bacteria which has accumulated within the water heater this harmless bacteria is nontoxic to humans D An excess of active hydrogen in the tank This is caused by the corrosion protective action of the anode Smelly water may be eliminated or reduced in some water heater models by replacing the anode s with one of less active material and then chlorinating the water heater tank and all hot water lines Contact the local water heater supplier or service agency for further information concerning an Anode Replacement Kit and this chlorination treatment Ifthe smelly water persists after the anode replacement and chlorination treatment we can only suggest that chlorination or aeration of the water supply be considered to eliminate the water problem Do not remove the anode leaving the tank unprotected By doing so all warranty on the water heater tank is voided
