Geberit concealed cisterns appear to be the de facto choice for quality when installing a back-to-wall WC. I used the Sigma 12cm UP320 unit. Very clever design and precise manufacture. The instructions were good and easy enough to follow. The unit comes up quite tall so just be aware that if you boxing in has to be limited for finished height. Other sized Sigma models are available in their range. Very pleased altogether and there was an appreciable range of dual-flush buttons to choose from - purchase separately.

Lucy Asked :Geberit has advised me to contact the supplier we intend to use to find which concealed cistern is most suitable for us. We are looking to save as much space as possible, a pneumatic flush and access to the workings through the flush panel (saves the worry it will be in a frame and tiled) and using a back to wall pan rather than wall hung. I'm not sure which cistern would be most suitable. Would you be able to advise, please? I hope to get all the necessary fittings before the builder is here; we haven't chosen a plan yet as it depends on the cistern depth. The builder usually uses a different brand, and I want to make sure he doesn't encounter any problem, so I'm doing the leg work :) Many thanks for any advice you can offer :)
Answered By QS Team :
Geberit does not make a cistern in a frame to suit the requirements you have mentioned. All our frames and cisterns are designed to work with wall-hung toilets. The only cistern we have for floor-mounted toilets is for use in furniture only and not mounted to a brick wall. In this matter, we are unable to assist.
Khush Asked :Is this system compatible with all RAK toilets? I have one installed, and the flush is so powerful that water splashes out on the initial burst. How can I slow this down?
Answered By QS Team :
The Sigma cistern (109.309.00.5) is compatible with RAK and other floor standing back to wall toilets. Depending on the answer you can adjust the flash accordingly to either 6lt or 4.5lt flush volume by turning the flush valve inside the cistern.
Phillip Asked :Hi Will this fit into cabinet depth of 320mm Regards Phil
Answered By QS Team :
Download Product DataSheet PDF. From PDF refer to the technical drawing. The portion in red circle is the maximum distance from the wall to the front of the cistern is 205mm. But if you want you can put batons behind the wall fixings to bring the cistern out further. You must put support, bracket or a block of wood fixed to the wall to support the flush pipe.
Alison Asked :Hi, I haven't' received a response to my query from a couple of days ago - please could you respond. I am asking whether this wall hung pan QS-V43395 is compatible with this cistern QS-V39530
Answered By QS Team :
For Duravit Darling New pan we recommend a frame and cistern and not just the cistern on its own. Therefore this will be 111.383.00.5
For 111.383.00.5 -- Refer this url
Alternatively, you can use the Duravit DuraSystem Standard Toilet Frame.
Natalie Asked :I see on the datasheet for the Geberit QS-V39530 that the height of the unit once installed is 108cm from the floor. I am wondering if this is a fixed height as I would like our boxing in to be shorter than this. Can the black flush pipe be adjusted to make the unit closer to the pan and therefore reduce the overall floor the top of boxing in height?
Answered By QS Team :
Sorry for the delay responding, the flush pipe to be reduced by 8.5cm as per technical drawing of the cistern.
