Cloudy tap water can be concerning. Learn about the common causes, from trapped air to sediment, and when to call a plumber.
The Glass Test
If your water comes out looking milky or cloudy, fill a clear glass and let it sit for a few minutes. If the cloudiness clears from the bottom up, it's simply trapped air bubbles, which are harmless.
Other Potential Causes
- Municipal Water Work: Work on the city water mains can temporarily introduce air or sediment into the lines.
- Hot Water Heater Issues: If only the hot water is cloudy, your water heater might need flushing to remove sediment buildup.
- Hard Water: High mineral content can sometimes cause water to appear slightly cloudy.
When to Seek Help
If the water remains cloudy after sitting, or if it has a strange smell or color, don't drink it. Contact a professional plumber to test your water quality and inspect your system.
