For the last couple of days the cold water from our taps (direct from
the mains) has been coming out of the tap cloudy. The cloud effect is
caused by tiny bubbles which gradually fizz out leaving the water
clear. There is no odour, colour, or bad taste so I presume its safe
to drink but where have the bubbles come from and why? It is the same
from all the cold taps bathroom and kitchen so I am sure the cause
lies with the water company rather than at home (we have not done
anything to the plumbing to have changed anything). Thanks.
