If you are constantly experiencing cloudiness in both the cold and hot water, the cloudiness is caused by tiny air bubbles. This air is under pressure in your water pipes, much like carbon dioxide in a bottle of soda. When you turn on your tap, the pressure is released, allowing the bubbles to appear, just as removing the cap from a soda bottle causes the soda to fizz. If you allow a glass of water to stand for a few moments, the air bubbles will rise to the surface. This phenomenon is called “entrained air” and does not affect the quality of your water. The water is perfectly safe to drink.
