A LOT to do with dual flush actually.
Since small amounts of flush are quite hard to achieve with a siphon system.

Then presumably the siphon one may purchase at

doesn't work. Experience says otherwise.

Experience says it does work, but that it's not dual flush (which TNP was
obviously referring to by "small amounts of flush").

Also, presumably, a toilet fitted with a Variflush
http://www.peterton.co.uk/index.html will not work with the knob
on the low setting.

Won't work at all with cisterns designed for a top-mounted dual-flush push
button which most of the designs being complained about in this thread
have. Plus it's so cranky-looking it wouldn't get past the door in most
SWMBO-dominated homes :-)

Any idea how they work? Presumably it's all patent-protected so that
no-one can make an acceptable-looking alternative version.
