Do modern toilets still accept a low pressure supply?

The valves are the same. When using high pressure (i.e. mains) a flow
restrictor is inserted into the valve. This normally consists of a
threaded
plastic insert that you screw into the water passage.

I believe that all modern toilets have a 6 litre maximum capacity (hence
the
rather pathetic looking -IMHO -diminutive cisterns). Is this correct?

Modern toilet pans are designed for the lower water flow. They work just
fine (and I'm quite capable of testing them to the limit). Don't fit a 6
litre cistern on an old pan, though, unless you do some testing first, as
they might not be reliable.

Respectfully beg to disagree.
I was contemplating starting a thread on this topic (although not for the
queasy) as I have noted that our new and new(ish) toilets do not seem to
flush efficiently.
I generally have to flush twice to clear all the 'debris' which defeats the
object of reducing the cistern size.

My main thought was 'how do they decide how much water should be used, and
how do they test it'?

Is there a British Standard Turd (BST)?
If so, where is it produced?
Also which committee defined it?

Are we now standardising to a Eurocrap?

Can you get an MSc in Advanced Faecal Transmission Science?

The list of questions is (unfortunately) endless :-)
