    Ive had this issue for over a year now

    When theres no plumbing in use (no washing machine,heating, toilets, taps etc) i get random knocking vibrating type noises (u can feel the vibration when u hold it) from the stopcock under the kitchen sink. This is the mains stopcock for my detached 20 year old house.

    Ive had the ball valve in the loft cold tank replaced recently and i dont seem to have any leaky toilets (i have 2 toilets in the house) so what could this noise be coming from? Im at a loss to know what to do!

    Check the stoptap is fully open it could be water hammer caused by your neighbours using their appliances.

    Yep the stoptap is fully open. My house is detached so didnt think it could be cos of my neighbours use of appliances

    Call your water supplier - they may have something odd going on in their main pipe further down the line

    Have you got a water meter fitted? If so this will be the culprit. Phone water board and they will replace with a new one.
