Cloudy Water

Air and pressure in water lines can make your drinking water appear cloudy for a few seconds.

Once in a while, you may get a glass of water and it appears cloudy or milky. Don’t be alarmed, if you look closely, it is only air bubbles in the water that gives it that appearance. After a few seconds, the water would clear up as the air bubbles rise to the top and dissipate into the air. This poses no health risk and your water is safe to drink.
