Why does my tap water sometimes look cloudy?

Cloudy water is often caused by air that enters pipes and escapes in the form of oxygen bubbles.

Air bubbles are more prevalent in cold months because water from outside pipes is colder and holds more oxygen than water in household pipes. Consequently, when the cold water enters your home and begins to warm up, the oxygen bubbles escape and cause the water to look cloudy or even milky. Construction in the distribution system can also allow air to enter the pipes and cause the appearance of cloudy water.

The air bubbles should naturally disappear in a few minutes. Test this by filling a clear container with water. After a few minutes, the air bubbles rise to the surface and the water should clear up from the bottom to the top of the container.

If the cloudiness does not disappear, please email Customer Service or call 949-459-6420.
