I have yet another worn bleed valve on a radiator. The key will no longer turn it. The large nut that houses the valve also cannot be turned with a pair of pliers (the long red handled adjustable ones) as it has been painted and this seems to have sealed it more. It's so annoying as the room is so cold because of this. I haven't got a plumber's wrench or anything heavy to open it.
What can I do ?
