Which Geberit Cistern Do I Have?
One of the most common questions we get is, “What flush plate do I need?” As I mentioned in our article on identifying Geberit Kappa cisterns, this question can always be answered by finding out which cistern you have.
Identifying the correct cistern and flush plate can be tricky. Many people move into homes where the previous owner installed the system. They often have no idea which cistern or flush plate is installed. To make things more complicated, Geberit makes four different cistern ranges, and the flush plates are not interchangeable. Knowing it’s a Geberit cistern won’t necessarily tell you which flush plate to buy.
However, there are key features you can look for to identify your Geberit cistern. In this guide, we’ll show you how to figure out if you have a Geberit Sigma cistern.
While I have your attention, if you find you have a Geberit Sigma cistern after reading this guide and are looking for a Geberit Sigma flush plate, be sure to check out our store where we sell our own range of UVO flush plates designed to work with Sigma cisterns, they offer a great low cost alternative .
The Flush Plate
If your flush plate is still installed, it can help identify your Geberit Sigma cistern.
If you are lucky , the code on the back of the flush plate will still be on .
You can see on this example the code is 115.770.11.5
Your code will be in the same format xxx.xxx.xx.x but maybe a different code.
You just need to type it into a search engine and it will reveal which flush plate you have.
Another way to identify is that Sigma flush plates are also usually around 246mm wide, making them wider than the Kappa and Omega ranges.
This leaves Sigma and Delta as the two possibilities. Fortunately, the design differences between Sigma and Delta plates make them easy to tell apart.
Now, let’s focus on the more common Sigma flush plates:Sigma01, Sigma 20, Sigma 30, and Sigma 50. We’ll skip the less commonly installed Sigma 10, 60, 70, and 80 models.
Sigma 01

Sigma 50

What If I have no Flush Plate?
I have many emails from people who have no flush plate to check, so what do you do if you have no flush plate ?
Well ,fortunately there is still plenty you can look for even without the flush plate
This is what you will see if you have no flush plate.
You can remove the back plate and the white cover which covers the access to the cistern
You will then be able to see into the cistern, where there maybe a part code as shown below.
This will reveal the cistern range, in this case UP320 along with a product code in this format xxx.xxx.xx.x
In this case you see it is 111.309.00.5 .
You simply need to then type that code into a search engine and it will reveal which cistern you have .
