    Radiator nut

    Radiator nut 14th Mar 17 at 8:45 AM
    I'm in the middle of decorating and have drained a radiator to pain behind it...simple I thought!! All was going well until I came to undo the lock shield valve nut to them remove it from the wall...it appears to be seized solid. The nut at the manual control valve was fairly easy but I can't for love nor money get the other undone...does anyone have any tips?

    If it assists...its copper pipes not plastic!

    Daft question but you are turning it the right way aren't you?

    Maybe try spraying a bit of WD40 in there and leaving it to soak for a little while

    WD40 or penetrating oil is always a good thing to try first. If that doesn't help, you can try heating the joint with a blowtorch - as the metal expands it'll sometimes be enough to just "crack" the joint.


    Obviously you'll need to be careful to protect the surrounding areas / wall from being scorched - either use a soldering mat, or you could improvise with a baking tray with a damp tea-towel behind it.
    I may not know much about art, but I know what I like.

    Sometimes tightening a nut first then tying to undo it will work.

    I would be very careful indeed or you will have yourself a big mess !!
    Why not leave the radiator valve alone & use one of these ??
    With an appropriate sleeve of course.
