Musty, mouldy or earthy tastes or odours can be caused by organic growth within water pipes. This is most commonly noticed if you have not used your taps for a while, such as returning from holidays. Try running the tap for a few minutes to clear the lines.
Before reporting your water has a musty, mouldy or earthy taste to us, we recommend:
Head out the front and try the water from the tap closest to your meter - is this water producing the same taste or odour? If yes, try running the tap for a few minutes to see if the problem resolves. You can always reuse this water on the garden.
If you have run your taps and the taste or odour problem persists, you can report this to us and we will investigate.
