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.
Cloudy Hot Water Hot water will sometimes be cloudy due to the physics of heating and moving the water through a pressurized system. As water is heated, the gases dissolved in the water will escape. (That's why most water heaters have a pressure release safety device.) As the hot water is released at the tap, the gases immediately begin to separate from it. The cloudy water will clear quickly. Dissolved air in the water will not harm you or damage your plumbing or appliances.
