If you mean the flap valve type.....
It seems to flush better. But I'm a bit worried about the system - in the
commissioning, ths flap valve stuck open once or twice. It was easlily
adjusted, but as I'm on a meter I sometimes wake in a cold sweat thinking
about it!


Hmm. Interesting. My experience with the US version of these has been that
the life span of a properly sealing flap valve is relatively short. 1-2
years. FWIW.
