of four factors which must all be present for the odor to develop:
a. a concentration of sulfate in the supply water.
b. tittle or no dissolved oxygen in the water.
c. a sulfate reducing bacteria within the water heater. (This
harmless bacteria is non-toxic to humans.)
d. an excess of active hydrogen in the tank. This is caused by
the corrosion protective action of the anode.
