Can anyone answer please. I have vibration under floors for the last two months, tangible, you can feel through soles of feet and it doesn't stop. Shared plumbing supply from mains in street - victorian conversion - 5 flats, two storeys and I am ground floor. Thames water have told me the supply has 4 bars pressure. Top flat recently had a water booster pump fitted. I'm being driven slowly mad. Does anyone know if this sounds like a high water pressure problem so that I least I know where to start looking.
Thank you very much.
