Toilet flushing system

[Spectric]

However the American flush valves is an altogether different beast, a massive brass valve sitting on top of 11/2ins pipe with a little toggle lever on the side, a flick of the lever gives a blast of mains presure water, in quick succession as often as you like, a bit aggricultural but very effective.

Sounds like they also have a very different beast to flush away as well !
