    Hi
    I have a built in cistern system (behind tile) that is operated by a dual button air pressure based mechanism. In short it's terrible. Worse part is that over time the button push has become difficult for anyone to use. I would like to replace it with a cable operated dual value and button. The problem is the button hole for new button. The hole for existing button is about 73mm while I'm told possible replacements seem to be about 60mm. Two different plumbers have shook heads and wished me luck finding a button solution. One would have hoped that adapters would be available in replacement situations like this. Any ideas and assistance would be appreciated.

    You could use something like a chrome plated or stainless steel washer to make up the difference. Did one years ago by making the washer out of a chrome electrical blanking plate.
    Have a look at https://www.accu.co.uk/en/shim-washers/62884-HSHN-63-80-0-1-A2 - you'd need several as these are only 0.1 mm thick.
