Why does my drinking water sometimes look cloudy when first taken from a faucet and then clear up?
The cloudy water is caused by tiny air bubbles in the water similar to the gas bubbles in carbonated soft drinks. AFTER a while, the bubbles rise to the top and are gone. This type of cloudiness occurs more often in the winter because the colder water holds more dissolved air.
Air can be introduced into the water after pipe repairs or other service disruptions.
