    Can this be done without draining the system?

    I've tried to remove a radiator and in the process of doing so when turning off the lockshield the top twisted/deformed. Is this a plumber job or can I do it myself? It was a bit stiff, but was moving - and then just folded in on itself.

    Might be possible to just replace that stem part. Not a job for the inexperienced without draining down.

    I was hoping that the stem could be replaced without calling in a plumber. Dammit.

    Does this happen to these parts often or was hamfisted/unlucky?

    I was using an adjustable spanner as opposed to the correct key.

    Never happened me, but I've came across a bent one that wasn't leaking, so I didn't touch it.


    Is yours leaking?

    No, but I need to remove the radiator. Valve seems stiff/seized even though I used WD40 on it and tapped it a few times.

    It's this type here:
