    I have a pipe making a loud rattling noise when I use a cold water tap off mains - it started yesterday and had never done it before.

    The pipes are not accessible until they reach the loft.

    Any idea of the cause? How can I fix it?

    Is this any cold water tap or just one.
    What you are describing is water hammer, normally happens on high pressure systems when valves/taps are being closed quickly or if you have loose pipework that requires clipping.
    It could be down to a faulty tap value, if there is no history of this previously.

    Thanks for the reply

    The Mrs called to say water was coming from the loft a seems like a faulty ball valve and badly fitted overflow combined.
