Looking to see where I can find replacement for old cobra tap replacement inset. The one in photo is for a bathroom wash basin, but I actually need one for the bath. The bath tap insert has a larger diameter, guess about 30mm. There was a discussion on the forum about these, but a long time back. I think there was a generic type replacement for them ? Any help would be appreciated. Thanks.
