GEBERIT
Welcome to the maintenance page for the Geberit Sigma 12 - UP300 concealed toilet.
You can now repair your toilet with the tutorials and compatible parts in stock.
If you have any doubts about compatibility, I invite you to identify it using the reference found at the bottom of the tank, and to insert this reference in my search bar.
If the reference is illegible, send me a photo in the site chat, I will help you find the right spare parts.
LEAK IN THE TOILET BOWL? BROKEN FLUSH VALVE?
In this video I explain how to choose your flush depending on the issues.
The trio of tranquility
mechanism with basin and float valve
If you're looking for truly effective maintenance, this Tranquility kit is uncompromising! It replaces all parts in contact with water, ensuring smooth movement and new seals for a perfect seal. Take a look at the offer that comes with this kit.
Rétro-compatibilité : Geberit a évolué son mécanisme et son bassin.
Included in the offer
The inseparable duo
Mechanism and pelvis
This is the new Geberit mechanism and basin designed to replace the previous generation. The big advantage of this mechanism is its water consumption adjustment, which allows for real water savings at the end of the year. In addition, the basin is equipped with an arm for easy attachment and an anti-splash adjustment that removes splashes from the bowl.
Included in the offer
The solo
Float valve
This Geberit float valve has three advantages. First, it's practical: it's easily interchangeable with the same model thanks to the white nut (in your tank). It's silent, slowing the water flow, ensuring smooth filling. Its adjustment is also easy: you have a white spiral rod that allows you to adjust the water level in the tank.
Included in the offer
Mechanism
This new mechanism is designed to work exclusively with its basin. It will be incompatible with older generation basins.

The perfect kit
Slotted cable gland
This kit is perfect for disassembling your slotted cable gland! The combo: WD-40 penetrating oil and an 8mm Allen key with sharp angles are the secret to extracting (without strain) the Geberit slotted cable gland. The emery cloth allows you to clean the body of the faucet. This area can be clogged with limescale. With this kit, you are sure to regain the use of your Geberit stopcock.
Included in the offer
The transformation kit
Handwheel stuffing box
Improve the use of your stuffing box! You may have noticed that the slotted cable gland is easily damaged by the screwdriver! The handwheel cable gland has a completely different use: It is practical, with its blue steering wheel, opening and closing are done without tools! Unlike its predecessor, it is robust and does not deteriorate with each use, making it more durable in the long term. It fits perfectly into the body of your Geberit faucet.
Included in the offer

During your maintenance, you may notice that a small part is damaged or missing. Below, I have grouped together all the other small parts that make up your tank.
Flexible

Equipped with its trigger rods, it allows the mechanism to be activated.
Stem Kit
2 rods for the trigger and 2 others to fix the fixing frame.
Flexible joints
These O-rings come in handy if they start to get cut or flattened.
Stem extension
Allows you to extend the trigger and fixing rods
Fixing clip
It attaches to the tank wall and holds the float valve.
Large hunting stirrup
Stirrup to trigger the main flush of the Type 212 mechanism, sold separately.
Fixing frame
If you have the old frame that attaches with screws, you will need this frame and the rod kit.
Sigma 70 Caliper
Fits on Type 212 mechanism for Sigma70 plates.
Hydraulic lifter
This block is the hydraulic actuator for the Sigma70 trigger plates.
Anti-twist clip
If your toilet takes a long time to empty, it's because it's scaled up... To fix this, you'll need to remove the bowl, scrape off the limescale, and replace the four Geberit sleeve gaskets. Written tutorial.
