FAQ - Why Is My Water Cloudy?
Answer: This is caused by excessive amounts of air in the water lines. Air can get trapped in high places in household lines or mains. This trapped air then saturates the water passing through it under pressure and gives it the white, milky look. Fill a clear glass with water and let it sit on the counter. Watch as the milky look disappears with time. This situation is remedied by flushing from your outside hose spigots.

Aerators at the end of faucets may also introduce air into the water and give it the appearance of milky white water. Remedy this by removing the aerator from the end of your faucet.
