Here are the items to buy if you have a water leak in your GEBERIT wall-hung toilet
Geberit seal kit:
Sealing gasket + profiled seal
(823.404 or 883.360) + membrane seal.
Do the maintenance once and for all with this trio of seals, it solves 100% of leaks in the bowl for sure.
Geberit seal kit:

Do the maintenance once and for all with this trio of seals, it solves 100% of leaks in the bowl for sure.
Joints individually
The GEBERIT sealing gasket
I recommend replacing this gasket when its surface begins to have:
- Blisters
- Limestone crusts
- A whitish color (sign that the seal is stiffening and losing its elastic properties)
The Geberit profile seal (version 1)
Seal Ref: 823.404 and 883.360
Replace the profiled gasket whenever you have a leak in the bowl. Limescale can build up and the outer lip can become completely squashed against the bowl.
The Geberit profile seal (version 2)
Ref written on the seal: 890.615
I recommend replacing the profiled gasket whenever you have a leak in the bowl. The main signs of wear are limescale crusts on the gasket surface and the outer lip is completely crushed against the white basin.
The GEBERIT membrane seal
I recommend replacing the float valve membrane when it is torn at the folds, also when its color becomes whitish. (sign that the seal is stiffening and losing its elastic property)
To put everything back in place
