Plumbing airlock help

[primalcarl]

The cold tap in the kitchen makes a really loud banging/vibrating noise when it's turned on more than a dribble. I'm presuming this is an airlock as the tap shouldn't be faulty it's only a couple of months old.

Any idea how to fix? Quite a big building with lots of rooms, if that makes it any more complicated

have you had any plumbing work carried out recentley?
are you certain its an airlock?

try holding the cold water pipe beneath the sink to see if you can suppress the noise when the tap is turned on.

A piece of hot water pipe was replaced in the roof the other day, they turned off the hot water for a while. No vibrating or noise with the tap unit removed and the water free to shoot out

not sure i understood that last bit.

is the tap spluttering when turned on?

Twiddle with your water pressure, Chances are it's either turned too high or low. Just adjust it little by little until it stops the noise.
(commonly known as 'water hammer')

agree with lozzy .
under your sink (or somewhere in the house) find the mains water valve . i reckon its turn up to much . just turn it down a little .
i aint a plumber but it worked for me
