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.
It is commonly caused by bacteria that form in a hot water heater when it is run at low temperatures or turned off for a period of time. To determine if the bad smell is coming from pipes or from water, fill a glass of water and walk away from the faucet before smelling it.
