Cleaning the bath this afternoon and the overflow (grille? thingy? - don't
know what you call it but it's the bit that the plug chain fastens to, as
can be seen in this Screwfix picture here http://preview.tinyurl.com/mb99m6)
came loose and would not screw back. Further investigation shows that it
never will screw back on because it's the bit with the metal thread insert
(captive nut, I suppose) that's broken away from the plastic back bit so I
suppose it means putting a new waste in.

Problem is, the side of the bath is tiled so only access is either rip off
the side panel and re-tile (plenty spare tiles left by previous owner) or
rip down part of the kitchen ceiling and go in from there - all for a 12
quid waste!!! (

What's the preferred method chaps? Or indeed, does anyone have any better
ideas?

TIA
