    Hi, each time a tap is turned on or toilet flushed anywhere in the house I can hear a continuous noise in the pipes but I can only hear this noise when I'm in the downstairs cloakroom where the stopcock is located. The noise sounds like a very fast tapping not really a banging noise though, could this possibly be from a water meter? The water meter is about 5 or 6 meters away from the front of the house. The stopcock has been replaced but made no difference.

    Cheers

    Fill a bucket/bowl from your fastest tap .
    a) estimate how long/ Guestimate flow rate ?
    b) Was this activity any noisier in cloak room ?
    ( than normal toilet flush )
    c) Does this only happen the once if
    more water is run off in a minute or two,
    or each time more water is drawn off ?

    Hi thanks for the reply, I tried it from the kitchen tap and the cloakroom tap, it was slightly quicker to fill in the kitchen but there wasn't any difference in noise. This noise happens each time water is drawn off, one thing I did notice is that the noise seems to be slower if the hot tap is turned on rather than the cold not sure what that means though?

    Thanks

    Could be a loose jumper on the stop tap

    Or water hammer

    Does it sound like pipes banging / a thud

    It sounds more like a tapping than a banging but it's really fast.

    Do you have a combi boiler or a cylinder ?

    Is your stop tap fully open ?

    Might be difficult to do, but if all else fails maybe you could have the stopcock disconnected from rest of house and join a temporary pipe leaving it, to outside, to see if noise still there.
    Normally grit in pipework or stopcock faulty or not fully open.
    Do you know if you have a pressure reducing valve anywhere on mains?
    If you still find noise you could ask your water company to check their end outside the property.

    The stopcock was replaced a couple of months ago as it was leaking, the noise was there before it being replaced but I'm just getting round to getting to the bottom of it now.

    As far as I'm aware there isn't a pressure reducing valve anywhere, if I got the water company out to have a look at their end and don't find an issue are they likely to charge me?

    Not sure, but in N.I. where I am, the water authority are very decent and never charge for anything like that. Ring your local water authority to ask if they charge for investigating their end, if you do decide to get them
