Concealed Cistern Problems? 5-Minute Fix

A very helpfull video, but one important notice: he is demonstrating it with a rather brand new system. If you are trying this with a system that has been in use for years, chances are really big that limestone has built up in all sorts of crevices, especially where the parts are supposed to fold but can't anymore because of the limestone, so they WILL crack. So you will end up with replacing the siphon or the floater in whole and those are not cheap. So if your system has been in use for years, and you want to take it apart to clean it as it is leaking, then the advice I got (when helas buying the replacent parts) is to first drain the water, then fill it up with a mixture of water with citron acid and let it soak for at least 24hrs so the limestone gets dissolved, or at least softened. At that is still not a garantee, as "those parts are made to be broken when seized up with limestone, so you will end up with buying the whole replacement part anyway" .

Great video, gives me confidence in fixing my cistern. 😊

Nice one mate... very clear and informative... cheers..

Thank you very much..

Access is still absolutely terrible...

You saved us Roger! Thank you for such a clear explanation and demonstration of how to fix our cistern. great job, thank you!

Thank you so much!! Brilliant

Thank you!

Thank you, Sir! You just helped me fix a leak in about 20 minutes that's been bugging me for two years!

I replaced the flapper seal, put the flush valve back in, had the cistern full up, water wasn’t leaking in to the pan - but after one flush it starts to leak in to the pan. Any ideas?

Amazing video. Super clear. Step by step. Ive just cleaned my system and everything worked perfectly. Thank you for recording this!

Thanks good job

What is it that goes wrong with them though ? Does the seal perish, is it scale.. what ?

Thinks for this. I'm about to attempt my own fix. Water keeps going in toilet after a flush. Very annoying 😂

Love watching your video. Im in Australia - wish I could get some insight into out stupid toilet. We have 4 Villeroy and Boch wall hung toilets in our house.
al work fine except for 1 - which continuously blocks. its disgusting.
Our plumber and builder seem to think its something to do with the 'fall' of the water and that in order to fix we have to rip up the entire bathroom. its a massive cost to do this so for 7 years we have put up with it. We have a plunger next to the toilet (Gross) and if the kids dont plunge the toilet after doing a number 2 - then the whole house stinks. Im seriously about to have a nervous breakdown.

is it a possibility that the plumber has set the water in the sistern at a low level ? is there any way to make the flow stronger and see if it works.... Im praying that this is an option and hoping you can give me some help.

Can you just add a limescale cleaner to the cistern

Roger you are a GEM! Just completed our Vitra and it matched your video to a T.
Dead easy and perfect result, I did replace the large silicone disc which I preordered as this was seeping water into the pan

Are the buttons supposed to be kept pushed or only pushed one time and let go in order to flush. Mine was recently installed but I have to keep the buttons pushed because otherwise the water stops flushing the toilet as soon as I let go the button.

What ever happened to those high up cisterns that flush any thing at great velocity, and were easy to service.

Legend thank you, all sorted!

Brilliant Roger - thanks for keeping it simple. I'm a DIY person and this saved me hassle and money.

Thanks so much👍

Are you Roger Piss be ! I guess there is something about names 😃 Thanks for da vid

Excellent but why did the cistern not fill with water to prove it worked ?

Just sorted mine by cutting a bit short the plastic rods! Thank you!

Are they all the same

Great and simple explanation.

Geberit cistern slow filling. Internals pretty much exactly the same as in the video. Took apart, couldn't see anything. Reassembled...filling OK. No idea what the problem was. On the plate behind the button cover was a QR code linking to the Geberit maintenance PDF. This explained a couple of points that differed from the video.

Thank you! This worked

Not sure you turned the water back on.....😅

Lajk ko je u 2024 ovde!

This is super helpful — well presented, and very accessible to someone like me who knows nothing about plumbing! I'm pretty sure it just saved me a plumber call-out. Thanks!

DISAPPOINTING that you missed the most important thing: listing your account number so all of us whose ass' you saved (literally for the ones living in a unit with only one toilet) can buy you a beer... THANK YOU!

(Edit: trying the super comment thing to honor my word, but the thing is not working. Will keep trying)

dear Roger , we have a situation on site , we are using a tece cistern 9400408 its 1120 height with a wall hung Wc ( cotto brand ) the issue is the drainage points on the cistern and wc do not align and are 4cm apart ..... is there any adjustments on the cistern frame .... please advise

This has to be the most video ever! thanks!

wow!!! hats off to you!!!! You are a natural instructor/teacher and really know the stuffs. I was solely able to follow it and fix everything on my flush in my first go!!!!

Didn't turn the water back on

thx man, just fixed my running built in toilet :D

👍

Skilled presentation, clear explanation. Thank you for sharing your craft!

Sir, you are my hero ❤, thank you so much for all these explanations. I repaired the problem myself in 30 minutes saving probably 100 bucks (that’s what they charge you in switzerland to do this kind of jobs)

Only just come across your video, it's great, I had no idea you could fix so many problem through the flush button panel. Unfortunately my leak is where the cistern outlet joins the flush pipe into the toilet itself! In order not to completely dismantle the whole thing I've managed to wrap amalgamating tape around the joint so hoping that works! Where could I get a spare flush valve for this model? (I'm in the UK)

Great video, worked for me, stopped the dripping.

Thanks, just the knowledge I needed!

'You were only supposed to blow the bloody doors off!!' You look and sound like blue-eyed Rob Brydon!!

I just want to leave a comment here of how grateful I am after watching this video. It really helps me to fix my toilet!

Just fitted a new float in a concealed unit and now have a bit of water hammer coming from sink tap, can you tell me why this happens please as this has never happened before and float has been replaced before and never happened. 👍

Great Video. Which brand/model cistern is this?
