There are normally two reasons why water may appear cloudy, both are usually harmless.
The most common reason is minute bubbles of air trapped in the water. These air bubbles are so small that they are not readily visible to the naked eye and customers often describe this as their water having a ‘white cloudy’, 'milky' or ‘chalky’ appearance.
Air bubbles in the water may be caused by for a number of reasons:
Another cause of white/cloudy water can be small particles in the water. These particles may have become dislodged from pipework or other water fittings within the property, becoming suspended in the water giving it a white cloudy/opaque appearance.When a glass is filled any such particles would slowly sink, leaving chalk like deposits at the bottom of the glass.
In both cases, leaving your taps running at a gentle steady flow for a short period should resolve these issues.
