    Hi Guys, I have a concealed wall hung dual flush toilet I bought 10 years ago. Its a ULTRA-ZSPXTY005FP.
    No longer available for parts.
    Is it possible to interchange the internals ?????????
    If so, how, as its seems things clip into place.
    cheers

    which part has failed? you can get replacements but it will take a bit to find it, you need to type part name + concealed cistern / wall hung toilet cistern and look in google images to match. All parts from this kind of cistern frames are replaceable, you can find same part under different brand

    flush, have changed the rubber seal at the bottom, but continues to leak slowly no matter what I do, have contacted the supplier but the brand has gone out of production

    remove the flush valve and place it in the diluted vinegar - slim and long vase that entire unit will be immersed - leave that for couple of hours this will allow to dissolve limescale residue and valve will work more freely. Other thing is - rim of the cistern itself where the rubber goes into contact with it- spray it with vical and again leave it for some while, when you clean the rim you need use non abrasive cloth, otherwise you will end up with replacing entire cistern. rubber seal- treat with boiling water prior installation- it will soften it and give a chance to set snuggly over the cistern outlet.
    PS- I come across many brands and units but tbh first time can see valve like yours
    PS 2 - there is same toilet for sale on ebay - £123 always better than knocking down the wall ...

    Just to let you know I did what you suggested and the leak is now down to put up withable dribble. I noticed when I took the flush unit out that the rubber seal had a smear of grease on it. I tried with and without the grease, but the grease (marine) definitely helped !! (couldn't feel or see any lime build up on anything, but the vinegar must have done the job)
    Just have 2 more questions
    - Have attached a picture of the valve, can you advise what the blue float does, and where it should be positioned.
    - Also have attached a picture of the duel flush mechanism, can you advise how these should be adjusted.
    Have asked heaps of plumbers for help to no avail but who needs them when we have you guys.
    Really appreciate the help.
    cheers.

    float will be in charge of adjusting low and hight flush level on dual flush
    push in mechanism if was working before removal you rather shouldn't touch, if there is a play between push buttons and those rods you can unscrew them for 1/6 anticlockwise turn of so and check after each adjustment if improved

    Hi, Just an update. The leak was still causing a problem.
    Finally got a camera down there and found that the replacement washer was 1mm too wide and not sitting flush, trimmed the edge and bingo, all fixed.
    Happy days :):):)
