Sanit 510 Universal Filling Valve, Float Valve 9.5 mm (3/8 inches) – for Flushing Cistern 510, 1 pc, 25.001.00.. 0000, Weiß

After some detective work, I figured out that Villeroy and Boch use Sanit for their fill valves of their concealed cisterns - which they call 'Viconnect'. The difference? Nothing, except that Villeroy will charge you £66 or more for the exact same item, made in the exact same factory, by the same people. The Villeroy part number for this item is 8L073300. It's now in place in the Viconnect cistern, and works fine. Why pay £200 for a plumber, plus parts on top, when you can get one of these and fit it yourself with the help of a YouTube video! Incidentally, the V&B Viconnect flush valve ( as opposed to the fill valve, which this is) is made by Geberit - also a lot cheaper than V&B, if ever needed.
