The most common cause of metallic tasting water is corrosion in pipework. Many old pipes and fittings in homes and parts of our network were made from galvanised iron, cast iron or copper, which may have become degraded over time, influencing the taste and/or appearance of the water.
The issue may be particularly noticeable if the water has not been used for an extended period, such as after returning from holiday or if a house has been vacant for some time. Metallic tasting water is also more common in large buildings or properties with long lengths of pipework.
We recommend you flush out existing water and draw in fresh water from the main. Begin flushing at the tap closest to the front of the property or nearest the water main and work back through the house to a tap in the back garden. Run your tap for a few minutes.

Our monitoring programs show the water we supply is safe to consume. If we have reason to believe otherwise, we will notify the public immediately – please visit service interruptions to confirm no alerts have been issued.
