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.
In some instances, the smell only occurs when using hot water. If this is the case, the smell is likely originating from bacteria growing in your hot water heater. This can happen if your hot water heater temperature is too low or if itâs turned off for long periods of time, like when you go on vacation.
