Fix a leaking Geberit toilet flush valve
ฝัง
- เผยแพร่เมื่อ 1 ต.ค. 2024
- All the toilets in our 5 year old house have been leaking for a while now. The Geberit cistern flush valve is letting water leak past into the bowl. We've also noticed a marked increase in our water usage.
Have removed each Geberit valve and found that in all three of the silicone (?) washers were covered in pimple like bumps. Water trapped in pockets under the first layer of the washers.
Ideally these would be replaced, however I've found a way to easily and quickly fix them.
- Update -
Have had a few water bills now and found:
Prior to the fix our water usage was 450 L / Day
After the fix our water usage was less than 150 L / Day
That's 3 toilets all suffering the same problem and resulting in a huge waste of water. Our water usage dropped by 1/3!
Spot on fixed the problem. On a broader note isn’t it interesting how flush technology has gone backwards as we used to have toilet cisterns at height that used the force of gravity to enhance the flush and a simple ball and cook mechanism that anyone could fix and an outlet where we couldn’t pretend there wasn’t a problem. Now with “water saving” advancements we have toilets where you need to flush a couple of times (no force of gravity) and where leaks go down the basin so you never get round to fixing it and over engineered German plastic Heath Robinson concoctions that you need to go on TH-cam to find out how to fix. 80,000s views so far, so probably a common fault - German/Swiss engineering is not what it was once!
Yes I think a lot of people are having problems with this flush mechanism. Totally agree with you they completely failed at the new water saving mechanism. It saves water compared to the old syphoning system for the first 2 years but then leaks and uses much more water for the next 5 until the owners figure out how to replace / pop the blisters on the washer.
Instant fix for me. Was fighting trying to solve this for a while, had seen the bubbles but did not think you could just pinch them. Wish I could buy you a beer in exchange of the money and headaches this saved me ;).
Brilliant! I was able to fix my own toilet! 66yo woman...so pleased. Thank you
I'm so glad I found this video. Fixed the continuous leaking. Easy fix, thanks to you. I thought I'd need to replace parts.
Thank you so much for putting this video together - this has been driving me crazy for so long. So simple and frugal, love it. (We had the same model)
Thank you for taking the time to record this. It saved me having to get a plumber in. You have done a service for mankind!!
Legend. My father in law’s in hospital, not looking like he’ll make it out. A plumber was going to charge my mother in law hundreds to fix it. Appreciate it.
Sorry to hear about your father in law, glad you could help them out.
You bloody legend!! It's 1:27am and the leaking toilet was doing my head in. 2minutes with a pin and problem solved. Thank you so much!
Legend! Have two of these units in our house that are about six years old and actually replaced the flushing units in both to sort the issue three years ago when it first started and at the recommendation of a plumber... not a particularly cheap exercise. One started again just recently so found your video... voila, sorted in 3 minutes! And not gonna lie, found the 'pimple popping' aspect kind of satisfying ;) Big thanks!
Another thankful person here ... same make of flush, probably about 5 or 6 years old, same problem. My cistern is a built-in unit, so had to access it all via the (thankfully large and easily removable) button system, but essentially the same solution. Thank you!
Legend! I was planning on swapping out the whole flush valve, this was a literal 5 minute fix. Thank you!
I was just about to replace the flush valve and then came across this. Thankyou worked perfectly; first nights sleep without being woken by a leaking and filling cistern in ages!!
Thank you so much for this! My husband has been trying to fix our toilet for the last 5 weeks and after watching your video I fixed it in five minutes!
Quite the same Geberit model, same problem, perfect solution! Thanks :)
I had the same problem - intermitant noise, which I thought was the seal on the shut-off valve. But I replaced that and it continued to leak. Thanks to your video I've now realised it was the bottom seal (NZ$10 at Mega). And yes, my toilet was installed in 2019, meaning that it is also now 5 years old. Same blistering on the seal (under side). IMHO this is the best video on the Internet about this issue. Well done!
BTW looks like this problem is universal with Geberit, judging by the comments from all over.
Hi. I have a Geberit concealed cistern. It has been leaking into the toilet bowl for a few months now but has recently got worse so I decided enough was enough. Having dismantled it (with the help of TH-cam) I initially thought it was the fill valve type 380 , lateral flow water supply connection and have just ordered a new fill valve unit. However on watching your video I thought - maybe it is the flush? On close inspection I too noticed a large blip in the large silicone washer . I thought this was part of the system. However I have pricked the blips and water shot out. There was some swelling around the rim. I didn't realise that these rings are made of several layers and water can get in over time. The cistern no longer leaks! - thankyou for this very helpful video. I may buy a new flush washer in the future but for the moment it is working perfectly.
Mate, I owe you a beer! a 5 minute fix. Exactly the same problem I had. The pimple issue was the same but only had 3 or 4 of them. all popped and no more leaks!! cheers
I owe the guy a pint too!
Mate, thank you so much for this video, I didn’t have the confidence to understand how that contraption came out! But this was exact the same problem with mine, fixed in less than 5 minutes. We’ve got 3 of the same toilets in our house. All started going wrong after 4 years. Loads of bubbles on the washer. Now fixed. Thanks 🙏
I took a slightly different approach: although at first I popped all the "blisters" as you recommended, in the end I noticed that the blisters were only on one side, and so I mounted the silicone seal back on upside-down (actually, it doesn't seem to have an "up" or a "down" side, really). It's fixed!
Cheers,
M.
Perfect!!! One of the most helpful TH-cam videos IMHO! Thank you 🙂 !
incredible That was my problem!!! thank you so much!!
4 years on this is still incredibly useful. Saved me a trip to the shop and the money a new unit would have cost. Thank you!
Sometimes truly useful videos find their way onto TH-cam, this is one of them. 👍
Really helpful video!!! Smart move mate! I done it the same way and it’s fixed 👌👌👌
My Geberit unit has just started leaking after 12 years. Hopefully it pops out as easily as the one in the video. But good information. Thanks.
Thank you, this is exactly what I had. Never seen a gasket fail like that. Very odd!
Thanks, in my case I noticed a couple of small water pockets but this was enough to cause a very time consuming and fair amount of effort into finding why the inlet was occasionally dripping. No water noticed in the bowl but then noticed the water level wasn't always the same when flushing (I used gaffer tape to mark the baseline cistern refill level). I burst these two water pockets but then reversed the seal too. I've ordered some replacement seals for just over £2 each. Plumbers can apparently charge £45 to fix this leak.
Thank you squire!
I had recently had the same issue start with one of our villeroy boch toilets. I had a quick fiddle but didn’t have the confidence to take the flush mechanism out. Found your video just now and voila! Problem solved 😊
Thanks, great video. Found pimple and popped it which solved problem. Very grateful!!
Thanks alot for this helpful sharing! This has also solved my problem. I was cracking my head on what could be the problem and getting a plumber is going to cost quite abit!
I have months of leakage / dribbling on the exact model, has been busy, thanks for the video that I followed and fixed within minutes. Yooohooo. Save a lot of money and stress.
Amazing fix! Worked perfectly for me. Thanks!
Top man cheers, I quickly noticed it was the valve washer as it had a couple of blisters on but did not think to pop them until I found this video, its stopped the leak whilst I get a new one sorted. great video and helpfull.
Wow thanks so much was exactly like you said, all working now and saved potentially lots of money
I couldn't work out the cartridge release mine took alot of pulling. And I would never of spotted the pimples. It worked. Thanks.
This is perfect!!! It fixed my leak, thanks for making this vid
Very well explained, thank you. I've been living with a leaking cistern for a few weeks and finally decided to search for an explanation. Fixed in five minutes!
Even though this video is 4 years old, it was an exact solution for our leaking Geberit toilet flush. It could not have been more perfect !
Thank you very much.
Mine wasn’t exactly the same the washer was covered in limescale. But 5 mins under the tap fixed it. Many thanks
I checked the seal on mine and it had an air bubble which is now popped thanks to your advice, thank you !!
You genius! Similar but slightly different mechanism (two clips to squeeze to get the mechanism out) but the exact same problem with blisters!
This looks like built in obsolescence to make me pay a plumber to put in a near zero cost rubber seal or rip me off for a while new mechanism!!!!
Fantastic, thank you, problem fixed.
Thanks! I followed your advice and popped the bubbles!
Thank you so much for sharing - problem fixed
Thanku sooo much really I was going to mad before 2 hours now I fix it same way thanku sooo much
thank you so much for this video it fixed my problem..❤❤❤
Cleaned the chalk twice (I thought that was the issue) and didn't solve the leakage.
Then I watched your video.
Who would have think there are some bloody blisters there?!
Thank you, man! :)
Ha wow I thought they were there by design. THANK YOU!
Great solution. I had the same problem and I have been able to fix it. Thank you so much.
Thanks for the great video, job done and saved buying a new seal - for now!
Hi Pal, many thanks for an excellent video. I had the same problem and sorted it with a pin. Another beer on me pal.
instant fix for me also. thank you! I miss to check bubble...after broke it leak ceased.
Bro! thanks heaps for the video. Had the same issue with the pimples on the washer. Owe you one, my friend
I have a simular problem bt i aint Got those bubles on. Bt it is that the problem. And its gumy not silicon. So i have to change that gummy part
Second toilet fixed thanks to you.
Really appreciate this tip.
Thanks for sharing this. It fixed my immediate problem. I've since replaced it with a new seal (£5 - proper Geberit, not an eBay knock off)) and they are now made out of a different clear silicone material which apparently should fix the problem permanently, so Geberit say.
Thanks for the info, can you send me the link to the Geberit link? I'd like to read over it. Cheers.
Absolute legend!
Fixed my problem💩💩
Thank you!!!!! I've fixed my leaking toilet!!!!
Wohoo. New Year’s Day 2021 and I came across this video. I have two of these cisterns in my house and your video fixed my problem. Amazing. You are a champion in my books.
I really don't know how to thank you for this! I had spent hours cleaning and fitting everything over and over again. I was about to go to the store and get a whole new flushing set, but thanks to the universe I found your video and it was exactly what I needed to do!
Dear, you saved my wallet and time. You deserve for Nobel Peace award 🏆
This actually works. Fixed mine last night. Great advice👍🏽👍🏽👍🏽
Thanks for this very helpful video 😊😊
thank you you were my second vido so i was super lucky had a comply difrent model
Followed your advice and popped the blisters and worked a treat
Exact same problem, thanks!
Thank you. Awesome fix on my toilets that are only 4 years old!
Thanks a lot. Solved the problem.
Brilliant ! ❤ sorted thank you so much for posting this
For years literally I’ve been looking at how the plumber fitted the the flushing module alongside the water inlet part, wondering why the flushing module would get stuck agains the water inlet part requiring me to press the flush multiple times to unstick it. and it’s as simple as Pressing two clips, rotating the flushing module till it didn’t touch the other mechanism and clipping it back in. I feel like such a dick for thinking I needed to pull the whole cistern out to fix it. I also found I need to replace the inlet water valve! My mind is now at ease because of this video!
Many thanks for this, sorted the flush exactly how you described, my flush is a Geberit 223.830.21.1 and was a nightmare to remove, just took a bit of force, turning it anti clockwise 45 degrees. Now enjoying the silence on my bathroom lol
Super super thanks for sharing the explanation!
I really appreciate this video my friend,simply showing how to twist and remove helps so much
Spot on mate sorted the new year dripping toilet, it’s January 2020 and your upload is still saving folks time and money! Quality stuff 👏🏼
Agree with comment below. I owe you beer too! Thank you!!
I have three Gerberit systems, the first one had this same issue at about 5 years, the second at 10. I'm ready for the third to fail. Well done jwelliottnz!
Brilliant fix. Thank you. I identified this problem but didn't realise they were water blisters, thinking it was just poor manufacturing. What a satisfying fix!
Great video. However, some models have two clamps on the side, near the bottom. So not a twist and pull. Just release each side and comes right off. Then popped the bubble and now water is not running. Great fix---thx a ton.
Useful information thanks
bloody legend, thanks mate from NZ
I had the same problem, fixed it yesterday
Have had 2 toilets leaking for months ..not any more thx to this little vid .
Many thx buddy..I've bought 2 replacement washers off eBay for 2 quid each for next time they start leaking.
Genius! And with the ease of disassembly you'd almost say that geberit designed it to be so easily maintained? Has anyone tried turning the seal over? Though I've popped the two big blisters on the top and a small one on the underside, there is a slight concave dish across the diameter of the silicone seal and I wonder if flipping it over will help.
I had blisters both sides, as long as they are all popped I don't think it matters which side you insert it. But give it a go and report back?
This was very helpful, thank you for the help 👍
Hi. I have tried taking the upper unit out of the cistern by twisting it, it twists but no matter what I do doesn’t come out. I don’t wish to over-twist and break it. Any tips? Thanks
There are some notches that must aline. Turn and lift gently. You can feel when it's aligned as the unit will come free. But without the lift it will only spin freely.
Wow! Fixed my leak on 5 minutes. I had one "pimple" that was difficult to find. Great video.
Fixed the issue it seems, thanks so much 👍🏼
Thank you so much! You're a legend
Legend!!!! Been driving me mad the past few weeks. Originally looked at the valves and they looked fine. Just watched your video and sure enough there were several of those little suckers. Similar to yourself 2 toilets, same issue, 4yrs old. I owe you a beer!
Excellent video mate. Just fixed my own toilet with your help. Exactly the same issue. £2.39 part off eBay. I thought I needed a new toilet 😁😁
AWESOME, thank you so much for the 'pimple' trick, I had two pimples on the seal which is up to 11 years old (possibly shorter but that's unknown, although possibly a date stamp on my 260 model '130428' so 2013 would be about right for when the toilet was installed new). This solved the dripping instantly. Gave the 260 flushing unit a good clean too as it was all a bit mungy black. I see replacement seals are now available on ebay, not needed as yet but maybe in the future. This video saved me £££s or at least a complete new assembly at around £50 and so much time. I've got another in the house so am well prepared. Cheers again fella.
Briiliant it worked fine many thanks
We have the same flush, same problem and, on expecting the washer, lo and behold the same ‘pimples’. I’d assumed there were solid - never occurred to me that they were poppable!
You’ve saved me cost of new flush plus hassle of fitting. Can’t thank you enough!!
Worked for me too. Same module. Also about 5 years old when it started leaking. Thank you!
Thanks that really worked well
Such at easy fix. What a legend.
Geberit pimple resolved.thx
這片GEBERIT止水墊片是矽膠材質，使用久了會變形及彈性不佳，最後會起小水泡，而影片中用針刺破，只是暫時止漏，過了一段時間，馬桶裡又會開始滲水，治標不治本，因GEBERIT止水墊片屬耗材，只要起水泡或彈性不佳，建議就換一片吧，全新馬桶上的墊片，大約可使用7～8年左右，而後面所換的使用壽命，就在3～5年之間，如水箱又投入藍泡泡或藍藍香之類的潔廁劑，會讓止水墊片產生化學變化，另自來水中的氯，也會讓止水墊片的壽命減短而漏水，以上僅供參考！
I used google translate on your comment.
WIth respect to "the gasket on the new toilet can be used for about 7-8 years"
Our toilets all sarted leaking after about 4 years. So around 1/2 the lifetime you stated. Next time around I'll see if I can source some replacement washers, but so far bursting the blisters has solved the leak. Perhaps when the washers get to their 7-8 year mark I'll replace them then.
你好，我住在台灣，我是專門在維修進口衛浴設備，據我觀察，我現在維修到的馬桶以及埋壁式的水箱，大都是10幾年前的，而那時GEBERIT的舊款止水墊片，是可以撐到7～8左右才需要更換，而現在這款透明的矽膠墊片（SILICONE），只能使用到3～5年，目前GEBERIT水箱零件，已廣泛用在各種歐規的馬桶上，如Villeroy&Boch,DURAVIT,LAUFEN,SPHINX,Jocab-Delafon等等....都是使用此款零件，而且也屬環保材質，另外一款德國GROHE的止水墊片，也是使用透明矽膠，美國的KOHLER馬桶，裡面的紅色止水皮也是有年限的問題，使用一段時間就會慢慢的分解，所以現在的水箱零件，使用壽命沒像以前的那麼久，都有一定的年限，再來建議水箱裡千萬別投入一些賣場的潔廁劑，才不會損壞水箱零件，造成水資源的浪費，謝謝！
Yes the short lifespan of these washers is concerning. My suspicion is that the mechanism allows the valve to close very quickly part way through the flush which (my suspicion is) causes cavitation, which punches a small hole in the skin of the silicon forcing a small amount of water in. The silicon then springs back sealing up the hole. This is pure conjecture however.
jwelliottnz I managed to get a replacement seal from Geberit in Illinois years ago. My unit is in-wall tank, very awkward to access. They admitted to the problem but made no mention of these pimples. Hey will probably mainly it for free. Otherwise a class action lawsuit may be worth exploring just for the seal. I like your popping solution. It is an issue with unstable silicone chemistry. Silicone roof coatings are encountering similar degrading of material and performance. .
@@timothydobson4657 Interesting, thanks for the information. Hadn't realised that Geberit acknowledged the issue, though am not surprised by this given the amount of traffic this video has gotten. Roof coatings are suffering too? That sounds like a much harder problem to fix, my cavitation theory is probably wrong then.
Thanks for that, very helpful, fixed two toilets in my house.
Many thanks! Very useful.
Excellent stuff - I'd found the dimples but thought they were a design feature as mine were equally spaced. Popping the bubbles didn't fix the issue for me, there was still slight leakage, but a replacement washer from ebay is £2.30, so replacing seems like a better idea in anything beyond the very short-term anyway.
