Cause of Cloudy Water

The cloudy water experienced by the customer is caused by tiny air bubbles (dissolved oxygen) in the water similar to the gas bubbles in beer and carbonated soft drinks.  After a while, the bubbles rise to the top and are gone.  Since cold water can hold more dissolved oxygen, this type of cloudiness occurs more often in the winter, when the drinking water is cold.  As the water warms in the plumbing inside the home the dissolved oxygen must be given off, thus the tiny air bubbles.  Aerators on faucets add more air into the water making the water look even more cloudy.
