Help to Fix a Click Clack Plug that won't Stay Down Drainage and wastage systems and plumbing help, advice and answers

[Womble67]

I have a click clack plug that no longer clicks shut (brass mechanism). It is not the rubber seal on the plug. The mechanism does not seem easy to remove - tried to turn anti clockwise with pliers but to no effect. Any suggestions or ideas?

Sorry but we need a bit more than that, images perhaps? There are so many makes of plug and so many ways of installing them that solving this is pretty much impossible from here
