leslie Asked :

Does Geberit sigma 1120 Duofix cistern frame support a Sigma 30 flush plate?

Answered By QS Team Answered by the QS Technical Team

Unfortunately, you won't be able to use a Sigma flush plate on a Delta cistern and vice versa.

Julia Asked :

Hello, You say in the description that it's compatible with the Sigma10 flush plate. However, these seem to be only Single flush. Further down in the description, you say this frame and cistern are dual flushes. I'd ideally want an inexpensive dual flush plate (like Sigma 01 115.770.11.5). Is it possible to pair the Sigma01 with this cistern and frame? I hope you understand where my confusion comes from (Sigma10 vs Sigma01).

Answered By QS Team Answered by the QS Technical Team

Sigma01 is compatible with Sigma concealed cistern 12cm (UP320). The other compatible flush plates are Sigma80 touchless, Sigma60, Sigma50, Sigma20, Sigma10 touchless or Bolero/Tango flush plates.

John Asked :

What is the difference between (111.383.00.5) and (111.384.00.5) WC Frame With Sigma UP320?

Answered By QS Team Answered by the QS Technical Team

The two frames use the same Sigma cistern, but 111.384.00.5 is more for contractors as it does not include the waste connection and wall anchors. These are usually used where several WCs are being used in a row, i.e. public loos. Whereas 111.383.00.5 is designed to be used as a standalone in a residential area like a bathroom.

Brian Asked :

Hi, I intend to install this or a similar frame on one side of a wall, passing the pipework through the wall. Obviously, this will create a minimum 115mm gap from the frame front to the back of the actual WC, which will be on the other side of the wall. Is this possible, i.e. with standard pipe fittings/couplings and the flush plate operating actuators? The other consideration is the physical mounting (not clear on drawings, can I do this by just inserting bolts/screws from the reverse of the frame.

Answered By Justin Answered by the verified purchaser You need a minimum of a 145mm gap. And fix it loads, then screw/grip fill ply in front so it can't move. Cheers.
