How your water looks is important to you, and to us.
If your water isn't clear, read our advice to learn more, or watch our video.
Black, orange or brown water
The most common cause of discoloured, dark water is a disturbance in the water pipes. Repair works or burst mains can cause harmless deposits to come loose inside the pipework.
What do I do if I have discoloured water?
You can check In Your Area to find out if there are any works going on that could have caused the discolouration.
Discoloured water will normally clear if you run the cold tap in your kitchen. You should run this tap for up to 40 minutes or until clear.
Don′t use your water-reliant appliances, or your hot water supply, until your cold water runs clear.
Cloudy, white water
Drinking water can sometimes appear ‘milky’ or ‘cloudy’ when first drawn from the tap. This is usually caused by air and disappears after a short time.
Cloudy water caused by air bubbles is safe to drink and not harmful to health.
Pink, blue or green water
Strange colours like pink, green or blue water can be caused by a number of things.
Copper pipes
Copper turns green over time, which can make your water turn the same colour.
Misconnections
A misconnection is pipework that is connected to the wrong part of the system.
If you have pink, blue or green water, please call us on 0345 782 0999, so we can help.
