Common Causes
- Trapped air bubbles (harmless — clears from bottom up)
- Turbidity from sediment, clay, or particulate matter
- Hard water minerals creating a hazy appearance
- Bacterial contamination (rare but serious)
- Disturbed sediment in private well or distribution lines
The Fix
If the cloudiness clears within a couple of minutes, trapped air is the usual explanation. Persistent cloudiness warrants testing. Depending on the cause, sediment filtration, whole-house filtration, or UV disinfection may be appropriate. ClearFlow tests your water to identify the cause first.

Frequently asked questions
Is cloudy water from the tap safe to drink?
Cloudy water from trapped air (clears in 2 minutes, clears from bottom up) is safe. Persistent cloudiness from sediment, bacteria, or minerals warrants testing before drinking.
Why is my water cloudy only when it's cold outside?
Cold water holds more dissolved air. When it warms up inside your pipes, bubbles release — causing temporary cloudiness. This is harmless and clears quickly.
Why is my well water suddenly cloudy?
Sudden cloudiness in well water typically indicates disturbed sediment, heavy rain introducing surface water, or a pump issue. Stop using the water and call ClearFlow for immediate testing.
