    Hi,

    I live in a 3 story town house. We have a kitchen and a cloakroom downstairs and couple of toilets, bath on the 2nd and 3rd floors.

    Since last few days we are experiencing a weird problem. Whenever we start the taps (either hot or cold or both) / flush the toilets on the 2nd / 3rd floors, we hear very loud noise from within the wall of the cloakroom. This does not happen if we use the taps on the ground floor only. This also does not happen when we use the taps on the upper floors at very low pressure.

    The noise is very loud and scary. What could be the problem?

    I have a plumbing and a separate home insurance cover? Would one of these cover any required work?

    Thanks.

    Is it a machine gun sound noise ?

    Hi Shaun,

    Many thanks for the quick response.

    Yes, it sounds like the machine gun.

    Thanks.

    Sounds like one of your toilet fill valves is failing remove the toilet lids and open a tap that you know makes the sound and watch for the water ripple in the toilets

    Should let you know which one it is

    Hi Shaun,

    I have two toilet / shower rooms on the first floor and a bath on the 2nd floor. Whenever I start any tap from any of these 3 at high pressure or flush the toilet and then start any of the taps it gives me this sound. So it's not a single tap that makes this sound.

    Moreover even though the taps upstairs cause the problem (apparently), it's heard only at the downstairs cloakroom wall. It's so loud that it could be heard up to the 2nd floor, but it clearly originates from the cloakroom wall.

    Thanks.

    Has it only just started ??

    If so I would check the cloakroom toilet fill valve then

    Only needs to open a smidge

    Hi Shaun,

    Yes, it started just a few days back. I will check the cloakroom valve.

    Thanks.

    Or if there's an inlet ISO valve turn that off

    Hi Shaun,

    It worked. After few checks as per your suggestions, including the isolator valves, I could find the root cause - it's my tap in the cloakroom that is vibrating under the water force. Couldn't imagine that that will generate such loud noise. It needs replacing.

    Thanks for the kind advice.
