Why is my tap water cloudy or milky?

Sometimes you might notice cloudy water from your tap, which can make your drinking water look milky or foggy. This is often caused by tiny air bubbles in the water, following a burst pipe or a faulty plumbing fitting. The following guidance explains what causes this and how to check and manage it safely.

To check if this is the problem, run a glass of water and allow it to stand for a few moments; the cloudiness should clear from bottom to top. To help fix this, you can try running the cold water tap at the first point of entry in to the property (closest to the internal stop tap) on a slow steady flow. While the tap is running, turn the internal stop tap on/off 4-6 times to help release the air from the pipes.

Cloudy water caused by tiny air bubbles in the water is not harmful to health.

If you've tried this but are still concerned, or you'd like more advice you should contact your water supplier.
