I need to either replace or reseat the overflow on my bath, as it's
moving slightly and is no longer watertight. Access to the
back/underneath of the bath is no problem. Does anyone here have an
idea whether these are generally a push fit or screwed together or what?

Normally the screw is on the front (i.e. inside the bath) of the
overflow, which tightens the rear
