Yes i did or how would i know the part number the problem is that all the suppliers i have gone to either don't know what i'm talking about or just can't be bothered and that's from John guest stockists.
So the question was does anyone know of a dealer who stocks these parts either locally to Edinburgh bearing in mind i have tried most plumming merchants in Edinburgh or a dealer close by or alternativly where i can buy them on the interweb
