Totally agree on the lack of effectiveness of nearly all
low-volume units - not met one yet which worked first-time,
which seems to totally negate the point (a low volume for
pees can be achieved with a two-stage flush system).

Strange, I've fitted a couple of 6 litre units and they've never had trouble
flushing. Maybe my huge heavy bombs are easier to clear than the average
floater.
