Hi all, We have a Ceramica Wall Hung Toilet which has a Ceramica Concealed Cistern Chrome Dual Flush Plate fitted. Both were from Plumbworld (I know, I know). Anyway, one of the buttons on the plate has come loose due to the plastic lugs on the rear of the plate breaking off. What I would like to do is to replace the plate with a metal one so it might last longer than the 2 months this one has. Are these things universal or do different manufactures have different fittings? Any help appreciated, thanks
