Geberit toilet flush (old model) replacement of the seal

Difficulty

Moderate

Steps

Time Required

45 minutes

Introduction

A running cistern can waste a lot of water - a repair is urgently needed. Actually, this can have two causes: either the seal at the outlet of the box is leaking (the bell seal), but more often the seal at the inlet valve is defective, this case is described here.

Note: this is an older, no longer up-to-date version of the Geberit toilet flush.

Dichtung Geberit 292.878.00.1

Step 1

Lift pressure plate from bottom to top, then remove
first unscrew the outer frame
then the inner cover. Carefully pull away to the front.

Step 2

Grab left and right and pull up quite vigorously.

Step 3

Be sure to turn off the water inlet, e.g. at this corner tap.

Step 4

The filling valve. Photo 1 with the surface box.
Photo 2 shows the valve in the flush-mounted box.

Bei der Reparatur lohnt sich das Lesen dieses Artikels. Habe versucht, das Nachfolgemodell einzubauen, das ist aber nicht so stabil gebaut und arbeitet etwas unzuverlässiger - da wurde an Material gespart, was man nicht hätte tun sollen. Hier beim alten Ventil ist das Gewicht gleichmäßig verteilt. Das Nachfolgemodell hat seinen Gewichtsschwerpunkt oben - mit Funktionsverschlechterung.

Step 5

With a water pump pliers, you loosen the union nut on the valve. So it is separated from the water inlet.
Remove the hose slowly so that no part falls out.

Step 6

With the surface-mounted box you can simply push the valve upwards.
With the flush-mounted box, lift the valve upwards and set it aside. then push on the upper part until the float releases.
Now you can lift out the parts.

Step 7

Here you can see the parts of the valve. The seal is the red dot!

Buchstäblich überall. Google nach Geberit 292.878.00.1

Ebay: "Schwimmerventil-Dichtung für Geberit Außen-Ø10mm, Höhe 5,5mm"

Step 8

Now the seal has to be removed and replaced. It is sometimes difficult to find out. Try a small screwdriver.
Figure 2 shows a defective seal (here black). Clearly a ring is pressed into it.
If the seal is still elastic, you can just flip it over. A new seal is really not expensive.

where can I get a new seal?

What is the white turning nut on top of the filling valve, and what does it do? If it breaks, what happens??

Thx

Ish Ord -

In my opinion it is a protection for the connection between the long white bar downwards and the grey part; a break should not, I think, diminish the function of the valve.

Step 9

When reassembling you have to make sure that the release lever engages correctly again. Use a screwdriver if necessary.

Conclusion

Repeat the steps in reverse order to reassemble your device.

I don’t like Geberit toilet. My all time favorite flushing toilet is American standard https://bestflushingtoilet.org/american-.... Really, I like this brand flushing technology.

That’s a great effort to share information about the Geberit toilet, but I think most people do not use these toilets. Here https://lueliving.com/ is a list of some best toilest. I’m sure that will be helpful.

In Europe, Geberit is very popular, and it is one of the few brands that provides parts/upgrades for older models (even going back to 1964, when they started).

Super mega klasse danke für die Anleitung hilft ungemein

Uwe Häcker -

Danke! Dichtung umgedreht und alles funktioniert wieder. Bester Tipp. Ich bin ganz glücklich (und stolz, dass ich die Spülung allein repariert habe).
