Sometimes you may smell rotten eggs or sewage when you turn on the tap. Usually the smell is in the drain not the tap water. The smell is likely sewer gasses caused by bacteria that live on food, soap, hair and other organic matter in the drain. You may also notice particles in the water that are not supposed to be there.
