Our bath has been leaking for a few days, and I'm pretty sure that water seems to be leaking from around the rim of the plug outlet. Is it possible to remove these? If so, how? It appears that the plug itself has a nut of sorts in the middle, but I can't tell whether unscrewing this will remove the plug. I've not been able to get hold of the correct socket set yet (15mm) so I wanted to check here, before I went and bought one.
Any tips would be greatly appreciated.
