When removing the shower drain plug the entire metal assembly came out with it and attached to it by the central fixing screw came the base of the black plastic "cup". I have managed to get at the broken part and removed it and ordered a replacement but am unsure about if - and how - to seal the metal part to the tray. It had what appears to be something akin to polyfilla around it.
Any help would be much appreciated. Many thanks. Vic
