dual flush
A dual-flush toilet is a variation of the flush toilet that uses two buttons or a handle mechanism to flush different amounts of water. A lesser amount of water is designed to flush liquid waste and the larger quantity of water designed to flush solid waste.
The system was developed by Japanese sanitary product manufacturer TOTO in 1960. It was equipped with two levers and built-in hand-washer, and was also revolutionary in that it reused the water in the hand-washer for flushing. However, it was not well known outside, or even within, Japan. In 1976, American industrial designer Victor Papanek proposed the dual flush system in his book Design for the real world, but the first practical implementation was designed in 1980, by staff at the Australian sanitary-ware company Caroma, with flush volumes of 11 and 5.5 litres. The design caught on, and a redesign in 1994 cut water usage to 6 and 3 litres.The dual-flush toilet has become almost universally adopted in Australia, New Zealand, Singapore, and Israel, with its use in new buildings often mandated by legislation in those countries. The more complex dual-flush mechanism is more expensive than many other types of low-flush toilets.
I need to adjust the large flush button because water continues to run after the cistern has filled up and the button does not return to its proper position, it stays depressed. The small flush button is working OK.
In which direction does the dual flush operating plate need to slide/be moved?
i have 3 sottini toilets with a compact cistern.
It has an ideal standard dual flush mechanism. 2" entry
The ideal standard is poor quality in my opinion, I have replaced the washer and complete unit several times but it always leaks within a short time (between 0-18 months),
I would like to...
I have just installed a Thunderflush dual flush cistern outlet valve. The unit sits to high for the lid and buttons to sit and engage as they should. I have adjusted the button height fully yet it is still about 8mm too high. What can be done?

My Dudley vantage pneumatic operated niagara dual flush valve is not refilling into the cistern and if it does it is very very slow.
I can turn on/off the cold water tap from the bath located next to cistern and water begins to flow into cistern albeit very very slowly.
Hi there, our flush valve is still raising but refusing to drop back down. Been to all the plumbers merchants but none have anything that will click into the existing cradle. Its going to be far too difficult to remove the cistern and replace the cradle.
Any advice pleas on where I might be...
Hi, I have a dual flush toilet that's leaking water from the cistern to the bowl. I've taken the flush system out cleaned the washer of gunk, cleaned the bottom of the tank and it's still leaking-in fact it was leaking more at 1st! I rotated the unit a little and it slowed down; I can't rotate...
Any recommendations for a push-button toilet dual flush valve, please (and must have a cable over 310mm)? Tried a Fluidmaster model but plumber says it won't fit the 2" flush pipe. Thanks.
The syphon activation cable on my old Bathstore A2432 dual flush valve has broken and I don't want to have to remove the whole cistern to replace the the complete unit. Does anyone know of a replacement valve the syphon part of which I can use to slot into the existing cradle, please? I hope...

Hi all,
I wonder if any can help?
I have a vitra dual flush plate model name is 'loop'.
All of a sudden the press buttons don't work (don't flush) They still spring back but don't appear to be pushing against anything.
Any help would be very much appreciated.

Hi,
I have a Dual Flush toilet siphon. It has 3 adjustment sliders on - not the usual 2. Two large ones on each side and a smaller one on the bottom. The two large sliders adjust the flush volume for the full and half flush. Any ideas what the smaller slider at the bottom is for? The toilet is...
It's a Thomas Dudley Vantage (TD 212-A) dual flush. Possibly getting on for 13 years old.
I'm not a plumber but I try to solve problems myself. I found members of this forum extremely helpful some years ago when I installed a replacement Mira shower - very proud of myself! I've had to sign up...
Hi
The push button on my Wirquin flush stuck so in trying to release it I managed to break the button! See photos.
As it's also leaking into the pan should I just replace the whole mechanism?
If so, what is a good replacement?
And is it easy to replace?
Thanks for any help.

Am I the only one who sometimes puzzles over dual flush buttons? There are so many variations and each one seems to assume you know which bit to press for long flush and which one for short.
Just a few examples...
... and then there are the large wall-mounted ones too. Is there an unwritten...

I'm in the process of trying to replace a leaking flush valve with a Flomasta Dual flush Fill valve kit. The problem I've got is trying to get the flush pipe connected into the base of the valve. The existing flush pipe is marginally too small, but might be OK with a suitable gasket but I'm not...
