yeh right, 'low flow';
another way of saying that it only uses 6 litres rather than the old 10 litre models; but, unfortunately the resultant flush is insufficient to fully clear the bowl of that nasty old excrement!
so if, after the second flush, it is finally successful, you have now used 12 litres, wasting an extra 2 in the name of conservation!
that's 'new math' for you!
flush it down next......
