Direct toilet flush valve

[ChemEnger]

I have previously come across a valve (French I think) that replaces a toilet cistern with an automatically dispensed volume of water for flushing a toilet, thus removing the need for a cistern.

All I can seem to find at the moment are ones for urinals and systems that simply lift a siphon valve within a cistern.

There is also something called a Sloan flushometer, although this only seems to be in the US.

Anybody got any ideas where I might be able to find something in the UK?

Saniflo make a WC that has no cistern... this might not be quite what you're after though

Thanks muggles,

I've had a look at the Saniflo and the general concept is basically what I'm after, but I don't need (or particuarly want) the macerator...
