    Sorry more problems! Had a pre installed ideal standard dual flush valve in my cistern (its the type that overflows internally). I noticed that it had a constant flow of water once installed, so took it off and tightened the bottom back nut (thinking it was the external seal)

    Once on again, it was still leaking. So I took it off, and had a look up with it full, and it was leaking internally, rather than through the external valve sealing washer.

    All the overflow, float settings etc are ok. So is this a return or is there another seal I can look at? Seems like everything I have had from ideal standard has had a problem with it...

    if you hold the valve half way down and twist it will come apart check if the rubber ring is seating fully.

    looking at your one the clip half way down by the overflow needs to be held in to release and the same on the other side

    you should be able to get to seal. i don't reconise that valve. sometimes you get a bit of rough plastic etc from when it was made.

    Hi

    Gerberit (**** spelling)
    Check mating surfaces are flat and free of limescale or whatever.
    Push the two lower lugs in and the body will come off. remove as much limescale from the guide rail in the middle.
    If that fail down to buildbase buy another 24.99+vat

    that cheap old rubbish from abroad that you get now days with new cisterns. i always change them for good english parts.
    i can't see pic fully but you must be able to get to remove the rubber seal.
    as on old ones they scale up after a few yrs and need cleaning.

    cheers for that..

    and you really change out all your OEM stuff with english gear? Are the valves that bad then or just deteriorate after time?
