Great Video. Which brand/model cistern is this?

Dear Roger. I can’t begin to tell you how much this has helped me today. Our system is a Geberit but essentially the same and when I saw the water slowly running into the pan I was horrified it might mean a total strip out of the bathroom wall! You have considerably added to the state of human happiness in our house! Many thanks, Colin

I live in the Bahamas and our new rental home has these concealed cisterns installed. I had a few sleepless nights when the WC started to run. The plumbers here aren't familiar with these systems and they have no hesitation to grab a jackhammer and blast away. And there is no way on to match tiles and grout. Your video is perfect. I was able to fix this in minutes. It was easier than fixing a classic cistern. We have high calcification in the water here so I cleaned up the float valve and what you call siphon as you advised and all is perfect now. If you come this way you can stay in one of my rentals on me any time. Thank you!

Great video. I'm a general builder who has been trying to get a plumber to service a Villeroy and Boch concealed cistern for 2 months now. Have spoken to about 20 plumbers.....you mention villeroy and boch and concealed cistern and all have said not a chance. After watching yours and other videos, I decided to do it myself. It was so easy that I decided to descale all 3 concealed cisterns in the house....took 30 mins a cistern. Have now decided that if general plumbers are that scared of these cisterns, when I retire, I'm going to start up my own concealed cistern servicing company 😂😂😂 Only joking....when I retire, I'll be fishing, playing golf and travelling 😀

Nice one Roger! Mine developed a fault yesterday, water kept draining into bowl. Took everything apart quite easily thanks to your excellent video, lots of Water stone and bits of old tile plaster and such. Gave everything a clean and put it back and its working like new. NOTE: there was always a slight trickle from the cistern into bowl (causing horrible skidmark looking stain) now there no a single drop dripping into bowl. Keep up the good work Sir!

Brilliant, Roger, thank you very much! You helped me fix two leaky Geberit cisterns over here in Poland. I had watched a good half a dozen similar videos before I found your one, and none of those lads were as precise and to the point as you were. Top marks!

Thanks for solving the mystery of how these toilets work- previous to this I thought if something went wrong they would have to rip the wall out. This makes me thinking I might get one.

This guy is great. I have lost count of the number of times I have done a job with his advice/videos. Thanks!

Fantastic video, thanks. I’ve had a misbehaving one of these since it was installed five years ago. The plumber had left the assembly rods too long and they were distorting the rear plate. Thanks again.

I definitely need to admit that you have such awesome skills getting around with these wall cisterns. Appreciate your teaching skills for any person without basic understanding of how cisterns work. Way to go... Thanks for this wonderful video.

Thank you. My cistern was a different brand but the basics were the same. I had spare parts because I had two of the same loo but didn’t end up using one when we reno’d. The flush buttons stuck, the intake going into the float had some kind of partial blockage and the water didn’t seal fully and trickled into the toilet. From a few weeks post install. The plumber left the area. Your video saved me hundreds. Champion. Not to mention I thought it may mean ripping off tiles and wall which would mean thousands. So grateful.

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!!!!

Brilliant thanks! I have got exactly the same system, but it's labelled Saneux. I had a plumber come and have a look and he didn't know how to do it and was talking about smashing tiles off. He suggested I contact the manufacturer to find out if it could be serviced through the button plate and if the parts were available. Your video has given me confidence to tackle it myself.

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)

You little legend! We ordered a part for $65 thinking it was the issue with the cistern running into bowl constantly. it didn't fix issue after hubby replaced it. I just goggled it, found your video watched it and just pulled the entire thing apart rinsed it all wiped out the bowl which had lots of debris in it and put it all back together again. My daughter was like way to go mum! Lets see if it remains silent (ie no leak present atm). I may have just sorted it out. Fingers crossed. Thanks heaps for sharing this video. Cheers Kathryn

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

So helpful! With guests coming on a holiday weekend, I wasn't sure what to do! So easy! No need to call a plumber! Thanks!!!!

I've got a bit of a love hate relationship with these things. With the introduction of low content cisterns they needed something like this which dumps the entire contents very quickly rather than a siphon which drags the water up and over the before the siphon starts going and has a lower flow rate so you need more water to flush the pan. The advantage with those is that they couldn't leak like these new ones do. A friend of ours had a massive water bill because she didn't realise hers was leaking. It's not always easy to see the trickle of water running down the pan. Mine has a Grohe flush valve and I recently changed the head because of this but to be honest it's lasted around 14 years so can't complain. Grohe stuff is pretty good. They are reliable but you have to watch out for that trickle especially if you've got a water meter. Good videos as always.

Thanks for another excellent Abacus video Roger! We had a wall hung Abacus cistern fitted last year, and we panicked when the unit would stick and not flush sometimes, within the week it was fitted. Turns out the float valve needed adjusting.

Instruction are great very helpful to solve my parisi toilet problem. Thanks mate

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

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

Thank you so much! I was scared to touch the toilet at first but I just followed you and it got fixed in 2 minutes.

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!

Thanks so much for this video. I hadnt got a clue what to do with my eight year old saneux concealed cistern that had a constant flow in to the pan. It would make noise every few minutes all night in my en suite and keep me awake. Followed this and descaled and cleaner the internals and reassembled and it’s fixed the issue. Thank you.

This has to be the most video ever! thanks!

Thanks Roger, just had new installation, one pushrod wasn’t not set correctly. Your video made it a very easy fix. Thank you. Excellent!

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

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

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

Fantastic how to video.. no bull no music just facts .. wish they were all like this !!

It's amazing how a professional makes it look so easy 😁

Roger, I love watching your videos, you explain things so simply and precise. I'm doing my plumbing course in the new year, cant wait. Thanks for your advice and videos. 👍

Thank you, Thank you, Thank you. I have a new Toto wall hung unit that leaks from the shutoff valve and the connection to the filler. Toto was absolutely no help at all. Your video showed by what to do. Now every thing works. You provide a great service!!! Toto should pay you.

Water was leaking out of my cistern. Thanks to this great video, I was able to clean out the lime scale buildup and stop the leak.

Thank you for this video, my button was pressed in and wouldn't stop flushing. This video helped me learn how to open it up and resolve my issue.

Can't thank you enough. Cheers Roger! So easy to follow your instructions, saved me some money so much appreciated.

If others like me are here to figure this out and cant open the cover plate, mine needed me to push right instead of up. You can feel for the spring he showed and push further that way.. There is not enough information on this topic, am glad this video is of good quality.

Thank you for the clarity. My daughter has this type of cistern and there is water dribbling down into the pan. So hopefully I will do my best to sort this out. Thank you again.

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

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

Thank you! This worked

This video is absolutely fabulous. Easy to understand, easy to follow. Made me feel so successful!

Spot on, need to get these installed when I re-do my bathrooms 👍🏼

Another good informative presentation Roger. I am shortly going to install that type of lav in my bathroom and now have some insight into the setup thankyou.

What a cracking explanation and video. Thank you very much. Absolutely brilliant!

Thanks a lot! Saved me a call to the maintenance ❤️

Thank you very much for your video! It has resolved the mystery of concealed cisterns for me!

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

Great and simple explanation.

Typical... You couldn't of released this yesterday mate, went to my first one of these this afternoon and my first thoughts were what the ells this but figured it out and guess what, the debris plate was missing... Great vid and keep up the good work.

Thank you!

This video just saved me about $300!!! Thankyou!

Using a completely different system but your video helped me! Thanks a lot! Had problems with new toilet kept running. The thingy in the middle was not places correctly.

Thank you so much for the video, saves so much time and money!

Thanks. Our new house has a concealed cistern and I was dreading the day I will have to fix something. Your video has relieved me of a lot of worry.

Rocket science not required. Just patience and common sense. Great clip.

Don't even have this toilet why am I here haha 😅

Many many thanks dear .it's very great video for plumber

Such a great teacher!!! cool calm collected and expertise in knowledge...might go ahead and buy a wall hung now I know what to do!

Great design and excellent video

Thanks for the video, I wondered how you would troubleshoot one of these.

Mr. Builder.. You have saved me so many nerves and also money for a plumber.... Thank you so very very much :D

Thanks, Rodger. You helped me to replace a broken Geberit syphon which is very similar. Someone else commented here about the plastic becoming brittle with age and that’s exactly what had happened in less than 20 years. Two small retaining lugs snapped off during normal flush and I had to replace the whole syphon unit. Not the most environmentally friendly design but I agree that the whole replacement procedure was straightforward thanks to the clarity of your instructions.

Great....you explained so well....thank you. I repaired my cistern in India.

Brilliant Video - Thank you very much. Followed your instructions to resolve the issue - Cistern now working like new Thanks again 😀😀

Plumber was useless - this fixed my issue -thank you

Very, very helpful video. Many thanks.

Thank you Roger, that was very helpful. I fixed mine by reinserting the flushing rod correctly 😊

Thanks, great vid and easy to follow. I have a similar system which works fine. However the flush is very strong which makes some water spit out of the actual bowl when flushing. How do you adjust this?

Many thanks.

Thanks so much. 😊

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 thanks. I had no idea how to take mine apart (it's a Geberit but looks pretty much identical to your video) before I watched this video. Issue turned out to be with the float valve which was leaking so had to order a replacement.

A massive help, thanks mate 👍

Although my concealed sytem is a little different, this video gave me all the information i needed to fix my leaking toilet - many thanks

Salvation! ... from a great deal of four letter words whilst trying to fix it.. it Worked for " Geberit " alas inlet valve had to be replaced , but it was exactly the same steps otherwise. Thank you so much !

Just fixed our cistern. Thank you...!

Thanks for your video! My set up is very similar but older and a different make. A big difference is it has a soft plastic water holder inside the concrete wall cavity. I could not remove the large central part in this one so I cleaned around it as much as I could. One PROBLEM: I did discover that there is a volume of water OUTSIDE the lining! Have you seen a concealed cistern before with this problem? When the lining is empty it pushes inward due to the weight of water on the outside. It looks like a jobs for a professional...

Thanks so much👍

Excellent video and explanation, watching your video has enable me to fix our toilet, and save me calling out a plumber for a trivial job, thank you.

Legend thank you, all sorted!

Would be great if all manufacturers did something lije this, I have a Roca one which keeps trickling so I'm hoping I can use this excellent video to fix it. Thanks for the clear instructions.

I haven't even got one but still had a watch

This was great, helped me solve my issue of the water not flowing through. Thanks a mill!

Hello, What knob adjust the amount of standing water inside the toilet. Mine is very low. I would like it higher.

Me: I can do this Also me: who are you kidding

Thank you very much..

FYI peeps, this abacus cistern and internals is identical to Rak/Roca/Gerberit concealed low profile cistern (save for slightly different debris plate / rod arrangement).

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.

Saved me a call to the plumber and lots of £. Thanks again 😊

It's 3:37 AM now,, Brilliant video, it's going to help me for sure. Thank you 💗😌

Rodge, you forgot to turn the water on 🙈

Thanks you sir .

Thank you for the good work

A massive help, many thanks

Thanks good job

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

Thanks

No doubt a great video. How to stop water overflowing?
