I have such cisterns, and they were on offer about 18 years ago, but
subsequently dropped to my knowledge.
Short flush for No 1's
Full for No 2's!!

However it seems many assumed short flush was malfunction, and pressed
again &
got full flush; so instead of saving water on No 1's, they ended up
using more.

Continuing from the previous thread, I think I'll have to replace at least
one of the toilet. Since I have a septic tank the idea of reducing the
amount of water used seems sensible. Quite apart from my two US books the
term "low flow toilets" is one that comes to mind. Now, I'm aware of the
dual flush idea but low flow implies reduced water use in all cases.

Googling for the term "low flow toilet" has bought up a small number of
references (amongst lots of references to toilets in general and low flow
shower heads) but nothing specific in terms of products, yet.

Am I just looking for a dual flow toilet? If low flow is a separate type
of toilet where do I find one? Can anybody point me at a website or a
supplier in West London, Berkshire, South Bucks, North Hants, Wiltshire or
Somerset?
