Click âDisease of the Week,â find rotavirus, and take the quiz to test your knowledge! Rotavirus is a contagious virus that can cause gastroenteritis (inflammation of the stomach and intestines). Symptoms include severe watery diarrhea, often with vomiting, fever, and abdominal pain.
The incidence of rotten egg odor or black water in hot water lines is due to the reaction of. sulfates and micro-organisms in the water that create Hydrogen Sulfide (H2S). This is a water. chemistry condition, rather than a water heater problem.
One caveat: if you have smelly water at one sink, but not all of them, dump chlorine bleach down the basin overflow, instead of into the water heater. Sometimes bacteria can build up in there, too. And apropos to that: make sure it's really the hot water that smells. There are places where there is so much sulfur in the water that hot AND cold water smell. Applying these procedures won't solve that. But if the water smells like rotten eggs, and you can smell it at every hot fixture, then these solutions will work.
