    What ho one and all,

    Around the house, we have three basins with Ideal Standard Ceraplan monobolc mixer taps with waste lever. Very much like this: https://plumbing-gear.com/ideal-standard-ceraplan-basin-mixer-tap-with-pop-up-waste-chrome-b7886aa-b7886-2706-p.asp

    For reasons that I don't understand, one of the taps has become loose (ish) and needs the simple task of tightening. Not a problem until I look underneath and cannot for the life of me, see how to do it. All illustrations I can find show a large C washer that the stud passes through with a nuts to tighten.

    But all mine have whatever it is, as shown in the photo. And the waste rod passes through the middle.

    What am I missing as I cannot see how to tighten it.

    Grateful of some insight.

    Thanks and toodle pip

    The large heavy horseshoe shaped spreader washers are the usual fitting, certainly the ones I've done.
    It's difficult to say without hands on but the large shiny piece of metal possibly takes the place of the "C" washer you describe; i.e. bridging the hole in the ceramic. To rotate it you'll have to remove the H&C feeds to give it a small turn.
    Personally I'd remove the monobloc and clean underneath and check if any "O" ring seal is OK. If I'm correct you may have to pack where the metal touches the ceramic in order for the seating to be in the right place to allow the H&C feeds to go through. Thread-lock may help too.
    I hope all that makes sense.

    Thanks. Yes, the bridge thing is what is spreading the load but I don't recall how I fitted it as removing the H&C while the tap is in situ is not possible. So the bridge piece cannot be turned.

    I will spend more time searching the internet; there is something fundamental that I am overlooking. If I am lucky, I still have the tap instructions, problem is, where did I safely store them?

    At a guess ,

    Remove the waste control rod, long reach box spanner up over the threaded tube ,tighten the retaining nut , then replace waste rod.

    If you disconnect the flexi H&C feed tails from the supply copper? you may find that they'll unscrew from the tap base.
    Often they are simply a threaded fit with a small "O" ring which provides the seal, as they're tightened into the threaded housings. If they are of this type they can be re-connected after the tap and spreader washer are in place and tightened.
    The waste rod sticks down through the silver coloured tube, which looks to be threaded on the outside and maybe looks hex shaped to take an Allen key on the inside. Remove the waste rod first, insert a hex key (from above?), tighten it up.

    Thanks for the suggestions. I finally found a pdf installation guide that shows both the fitting that I have and the C washer. Seems there is a hex fitting inside the threaded rod but makes no sense why that would not be obvious at the end rather than inside.

    Now to find the tools that I know I filed safely somewhere.

    Don't think unscrewing the tails is an option; I don't recall my modus operandi but I fitted them myself and am pretty sure that I would have ensured the tails where well screwed into the tap base.

    SWMBO has some other jobs lined up for me today so will post back when I have do the job.

    Again, thanks.

    Released the rasing rod from the plug lever and removed and sure enough, the inner core of the threaded stud takes a hex spanner. Didn't find the original but have a set in the tool box. Tightened and put together.

    The strange thing is, one would think that to tighten, it would turn clockwise but that only undid it. Turned anti and now nice and tight again.

    Probably should have removed entirely, cleaned and fitted a new washer, but didn't so that is just a reflection on the quality of my work. Shoddy!!!! Not usually the case but suffering CLMS (Covid Lack of Mojo Syndrone)
