Do modern toilets still accept a low pressure supply?
I am replacing a 1970s bathroom and, for some reason, a low pressure
supply was laid on to the original toilet, despite having the rising
main going straight past.

Also, what are opinions on the new 6 litre flush limitation?
Having had a drain block last year, I prefer to stand the cost of
slightly higher water usage and send a good slug of water down,
particularly where "solid matter" is involved.
Has anyone suffered from increased drainage problems due to the
reduction in water flow?
I believe that all modern toilets have a 6 litre maximum capacity
(hence the rather pathetic looking -IMHO -diminutive cisterns). Is
this correct?

The pressure of the supply is compensated for by different nozzle/washers in
modern filling valves.
Disadvantages of having toilet rising main fed are a) can't use it when
water is cutoff. b) Lots of condensation on cistern for 5 months of the year
when the incoming water is cold. This is esp bad in a steamy bathroom.

All new toilets and refurbs have to flush with 6 litre of water max. Thats
been in the building regs for a couple of years at least.
You won't be able to buy a new toilet that uses more.
I have 2 new type and one of them is quite easy to block if more than a
average amount of paper is used.
Its such a nuisance that I'm thinking of putting a sign of the door
"No solids in the downstairs lavatory please" as in League of Gents :-)
