How A Dual Flush Toilet Syphon Works

In this video we demonstrate not only how a syphon works but also how the dual flush function works.

2:00 Keeping the handle pressed means less water. *THAT* was counter intuitive...
Simple but ingenius solution

Fascinating, sounds like a good system but I'm used to toilets where you hold the handle down for a full flush, so find it counter-intuitive. Do you provide a sticker or something so users know how to choose the right flush?

The best syphon on the market far better than any other make and a reasonable price

[johnbarnes]

Why I think it’s the best is if you only fill the cistern half filled your cistern will still flush the water away no other syphon will do this .Find your drop valve a little bit expensive thought if you priced it just below mcdee and fluidmasrer you increase sales massively although I’m not an accountant

What a weird solution .

We have ones where you press a button which tilts .

And anytime you want to stop it you press it back .

The only thing this button does is lifting or lowering a central shaft with a plunger on it .

It's dead simple and you have total control over how much water you flush .

Sounds very counterintuitive, a pushbutton toilet with a big button for a full flush, and a small button for half flush is much more intuitive, though this still a pretty cool solution

I have the same one but it's from 1967 so it has a ball with a tap inside and I did not know it was also made to save water 😉

Counter intuitive, pull and release should be half flush, pull and hold should be full flush, to rid us of those Klingon! 🙄😆

Possibly the most ridiculous invention in history. The concept of half flush is totally meaningless unless you know how full the cistern is in the first place.
