  • Plumbing question…knocking noise from pipes?

    So had to use/adjust water stop-tap recently and ever since we get some knocking noises from pipes, usually when cold tap is turned off, BUT I can also hear the noise when there is nothing else being used i.e. no heating, no washing machine, no WC flush etc (I know as I am the only one in the house at the moment!).
    So any ideas, trapped air! problems with water supply? for info system boiler, immersion cylinder, tanks in loft. Not been in loft yet, but is there anything to see, pipes all insulated?
    Is this just too much pressure affecting some loose pipes or air? Any advice appreciated. Thanks Chris

    Could be the header tank valve bouncing? This would happen after it refills which will be after you have used some hot water / cold water in the bath / shower.

    use/adjust water stop-tap recently

    You did turn it back full on, absolutely full on (maybe a little bit of a turn back off just so it doesn’t stick, but basically fully open) didn’t you?

    I had this, and it turned out I’d not opened the stopcock the full amount.

    If so, go and do that, and it should fix it. There’s no reason to have a stopcock not fully open, doesn’t change the water pressure in the house, and leaving it like that makes pipes go bang (and can be bad for pipes and for the stopcock so I’m told).

    Joe, good advice, initial test seems to have worked, 2 points 😉

    I’ll post an update if the ‘tune’ changes!
