Geberit concealed tank disassembly and reassembly

My toilet started leaking. Quick inspection revealed that the flush valve seal has some strange texture.
Geberit's part number of the seal is 816.418. I bought a replacement in local shop, but they are also available on Amazon.
Since I struggled a bit during the inspection, I filmed the disassembly and re-assembly while replacing the seal. I hope it saves you some time.
--- Note: The flush assembly can also be removed without removing the inlet assembly. Since the manipulation space in the tank is smaller in that case, you can fold down the green and gray levers which stick up from the flush assembly. That makes the assembly shorter and allows you to take it out easily.

Thanks , I am belgian but your explanations are very useful

[@petecurran3995]

Nice job! 👍
I replaced main flush seal but still have small leak. So I need to clean the float valve assembly, as you have done.

[@llewellynGS1]

very nice video it really helped me. Mine is the same model. The valve seal was fine, but there was a lot of calcium build up and I cleaned it, also with vinegar.

good jop

Thank you for your help. Without this I should have called a plumber. I was not the only guy who was looking for such rubbery ring in the shop. Such a coincidence...

[@tothf]

Thanks a lot! I've successfully fixed my first toilet ever with the help of your video. Bonus for mentioning the part number need.

What to do if the tap is leaking?

[@michaelhaigh6063]

Couldn't have done this without your guidance - really helpful, many thanks

[@niterayn]

Thank you for this. I couldn't figure out how to get the central bit out and you turning it upside down inside the tank provided the answer. My thinking was I needed to disassemble it inside the tank and that would've been much harder. I didn't need to replace anything, just clean the tons of limescale that has accumulated.

[@LubDubFox]

Thanks for the help mate! Really useful. Without this I would've probably broken something. :)

Hired a plumber to fix my dripping toilet. He said he "adjusted it", but he couldn't do better without ordering new parts.
He charged me a lot and it didn't fix the problem.
Turns out the toilet just need a maintenance clean after 10 years (from the previous owners). No new parts were needed.
You probably saved me about $1000 with this video.

Very good RUclips I have the same Geberit concealed tank and need a new part. Do you know the model name and number of this concealed toilet so I can order the correct part ?
Many thanks

[@marekf5]

This would be Geberit Kombifix, the number (visible at 2:00) is "110.302.00.1". If this is the same cistern you have, you may be looking for this: catalog.geberit.co.uk/en-GB/spare-part/Sigma-concealed-cisterns-12-cm-(UP300)/SPT_461052.html

@@marekf5 I see this datasheet everywhere. However, in the Look Inside at ruclips.net/video/Z8df_7aw9HA/видео.html you can see the basket/cup that the green flush valve rests in?
That thing is not listed on the datasheet. That valve and basket have been replaced by the 212 universal flush valve. Everything looks like it's literally a 'drop-in' replacement, but for the life of me, I can't figure out how to remove that old basket. With effort I can make it turn, but either I lack the strength or dexterity to get it out of the bottom of the tank.
Anyway, thanks for the video, this is an exact match of my setup. Unfortunately I need to replace a little more than the seal. ;-)

[@marekf5]

@@HenkLangeveld I see what you mean, but sorry, I cannot help. Never tried to dismount that one.

[@blogaquinaweb]

@@HenkLangeveld I have the exact same issue Henk, did you manage to find a solution?

[@engrshairkhan]

Thank you man. You are great. The sign you did exactly at 3:00, I like it..:)

[@marekf5]

No offense intended :)

[@diegoramos7768]

Hello I need some help I would like to know why is no water pressure when I flush the toilet

[@l.e.4695]

Hi Marek. The clip holding the inlet valve level broke. What is the model number of this cistern?

[@marekf5]

Sorry, no idea. Maybe the number visible at 2:00 will help, I do not have anything else.

[@fortheloveofseve6275]

You complete superhero. Thank you so much!

[@11ShawnLu11]

Thanks a lot from China!

[@engrshairkhan]

I have one question: The unit (at 4:51, whose rubber flush valve seal you replaced) can be further disassemble? Is there any other seal inside this unit to be cleaned or replaced?

[@marekf5]

Hm. It should disassemble further, I think, but I would not expect any other seal in there. Have not tried myself though.

thanks a ton...god bless you

Absolutely brilliant, thank you!
