    High pitched note from mains water pipes

    I have a flat in a 1920s UK block. The mains water feeds ~40 flats, of which I am one. There is no local boiler, though there is a communal one for the whole building. Recently, always at night, the mains water pipes have started to vibrate at a high frequency - emitting a "singing" note .

    Noisy pipes on cold main

    I am perilously close to losing my mind - so any help appreciated! About a month ago a vibrating sound started on our cold mains (copper pipes).

It's currently a concrete slab and he's going to lay a thin (a few mm) of sand on this to level out any imperfections, lay 80mm insulation (I guess will be 'Celotex' type stuff) and then chipboard flooring on top. I need to...

    Water pipe whistling

    Hello folks, I live in a block that was built about three years ago. At some point last summer, I began hearing a high-pitched/piercing sound coming through the wall.

    Push fit soil pipes..

    Does it matter if they aren’t fully inserted, as long as they go past sealing ring? I cut a bit of pipe 1-2cm too short and can’t get it out the other side to change!
