Geberit toilet repair and maintenance - How to

Showing how to disassemble a Geberit in-wall toilet carrier tank for cleaning, maintenance and repair.
To remove the button panel, push the panel slightly up and then lift it off of the wall on the top.
The lever assembly can be removed easily. Just make sure to stay clear of the two levers, which get pulled up in order to flush.
Don't forget to close the shutoff valve.
Cleaning off all of the seals should fix most of the problems with a constantly running toilet.
During the entire procedure the only tools you might need are pipe wrench and some pliers. I used both of them to disassemble the fill-valve for cleaning.

This is where I found the replacement valve gasket on Amazon:

I am a plumber, but was somewhat confused by an on-going problem with a Geberit in-wall cistern. This video cleared things up. Thanks.

Thank you thank you so much; we had spent 1300 Euros over 6 months, on three plumbers who not only didn't fix our leak from tank to bowl, but made it worse. Seeing your videos made me look deeper into the issue and I fixed it within 10 min!
We are grateful to your sharing.

Thank you, sir, for your excellent instructional video, which gives me the confidence to tackle a leaking Geberit toilet. Who on earth would give this video a thumbs down?

Was a handyman in the states for years. Living in italy now realized the systems are completely... foreign. first video I came across and now I think im good thanks

[johnrnyc]

Thanks ! Would not have been able to repair without this ! Our building had the water shut off and when the water came back on, the toilet wouldn’t stop running. I took off panels, shut off water, cleaned all the pieces put back together and it worked! Great video!

Fantastic video, thanks!!! I would just add one thing: Inside the valve that you remove at 4:00 there is a very small through-let that can get blocked by chalk. It then takes hours for the reservoir to fill. In my region with very high chalk level in the water, I have to open and clean this valve every 3 years. A bit tricky but with a small screwdriver one can bend both legs of this valve and open it. An alternative is to dump it in a glass of vinegar for a full night.

4:38 thanks, that was exactly right! One small thing I encountered was the calcification which makes it hard to release things. Vinegar helped.

Super helpful video, thank you so much. Just fixed our constantly leaking toilet with a £5.79 seal from Amazon (a pack of 3!).

This a valuable piece of information for the maintenance side of things. You took the time to explain the process in your video tutorial. I do appreciate you sharing this for others to learn and reference going forward. Thanks and good luck 🤞

Very good video! Don't forget to open the inside water tap before you close everything up and decide to use the toilet at once!

[ali-kadar]

Thank you. This saves me from calling the plumber who would charge (per hour) more than the price of the Geberit flush valve kit and would give the earliest appointment in 2-3 weeks.

[aristat]

Thank God for this video, I could NOT sleep with the constant flushing noise, and it only took a couple minutes to fix this. Can't believe I could have had to call a plumber for this otherwise lol

[simonetb]

Thank you for the vide! These toilets can be very tricky to install properly. I would not have been able to do it without your help!

[alexandraalbrecht]

Thank you!!!! You saved our daughters 10th birthday! She actually helped with the repair!!! This instruction is fantastic!

[stoker]

I just got mine delivered today with loose parts in the tank so this video confirms I had it put together correctly. Thank you! So easily serviced and well designed!!

[pinballwizard]

I have a slightly different unit but the design elements are the same. Managed to disassemble the unit using these instructions to re-attach the hook to the plunger which had become detached. Now working perfectly.
Thank you

[neilrussell-bates]

Thank you for this. I have watched other videos about this cistern, but I think this one may have finally helped me stop the water trickle!

My Geberit looked very different on the inside (perhaps an older model), so it took me 2 hours to get alle the parts out through that tiny wall hole. Your video still gave me the courage to try. Thanks for that. Why do they have to make those wall holes so tiny you can barely get your hands in there and you definetely can't see what you are doing? That is a crime against humanity to make wall holes that small... anyway thanks for the video.

[monkeyj]

very useful video and simple to follow instructions. ty for making this
