Odor from the hot water system
Many water supplies contain sufficient amounts of sulfur to produce an odor, often called
“sulfur water.” Sulfur water can be caused by a chemical action or by bacteria. Generally,
sulfur water is not harmful, only unpleasant to smell. Refer to the water heater
manufacturer’s owner’s manual for details on eliminating the odor from sulfur water.
Odor from sulfur water is not a service problem.
