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 odor of hydrogen sulfide gas can be detected in water at a very low level. Smell the water coming out of the hot and cold water faucets. Determine which faucets have the odor. The rotten egg smell will often be more noticeable from the hot water because more of the gas is vaporized.
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.
