Perfect, I've been putting off sorting this slow leak for ages because I thought it would be too complicated. Done in 5 minutes, piece of cake thanks to your video, you're a star! 🌟
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.
Ive took mine apart it looks almost the same inside just have the led version. If you want some pictures and such. Can supply them. The grease is between the fan and the pcb box
Brilliant! I suspected it would be a faulty washer like this, but dreaded having to figure out how to pull the whole mechanism apart in order to get to it. You showed us that it came out with just a simple twist! THANK YOU!!!
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!
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!
Thank you so much, mate. You are a legend! Been battling with 3 leaking toilets in our house for months. Popped the bubbles and now they're all perfect again.
Worked for me too, 3 toilets all fitted at the same time 5yrs ago all failed within 2 months, this fixed all of them with bubbles on the washers! Thanks
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.
Thank you for posting this. Changing the seal was simple (and cheap)and solved the leaking toilet problem. As you described, our seal had a bubble of water stuck between the two layers of the seal. I expected the seal to be a single thickness of silicon, but evidently not. I presume that once any crack forms in the joint between the layers , water gets drawn in over time.
I think Geberit should put this 'solution' in the manual or at least let installers and plumbers tell new house owners about it. By the way how long did it last after the fix? And is there any scientific explanation as to what causes these water pimples?
My fix still isn't leaking now, years later. My suspicion is that the silicon has a harder skin, when the flush valve slams shut it causes cavitation bubbles that then collapse injecting the small bit of condensing water vapour through the skin, into the seal. That is my untested hypothesis.
Mate, you are a legend, in every sense of the word...that's what you are! Seriously you served me $$$ from calling in a plumber who was going to charge me a fortune and maybe even ask me to replace the entire cistern system. For several weeks now I have been trying to troubleshoot the 'hissing' sound in the bedroom toilet. For me the 'leaking' wasn't obvious so I spent time on an Internet goose chase following wrong leads trying to fix the inlet valve to no avail. Luckily I resisted the urge to call in a plumber until I stumbled on your video by chance. It worked like a charm, one big lump and 2 tiny ones... and the hissing is gone... Legend!! ❤🙏
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.
Thanks. FYI. You can buy the Geberit gaskets. I found after popping that soaking the bottom of the unit in limescale remover like Kilrock took a load of scale away as well. Cheers. Great vid which saved me £50
Thanks from a fellow NZ’er , I have the same brand toilet installed 10 years ago. Can’t find any info on the brand online except minimal info from Australian plumbing suppliers. I have tried to get the valve assembly out , trying to twist as you did but it won’t release, really scared of breaking it. I have tried and tried but it will not budge. I can twist it a full 360deg with no success.
Understood. It's not intuitive. It's not the twisting, the twisting aligns the tabs so they can release up. Otherwise it just spins. So turn a little with slight vertical lift pressure, doesn't take much. Keep on turning until the tabs align then it will just lift free.
You kind sir have saved me a considerable amount of money 💰 I took your advice and with some upward force it came free, it has a few blisters but decided to go to Bunnings (being an Aussie brand flush system I thought they may have more compatible parts) and for the enormous sum of $4.95 I purchased a new seal , it's installed and leak it does not 😅. I also purchased a second seal for when the other toilet begins to leak
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.
Thank you brother - had this exact same problem and yes, it was bubbles on the silicon seal. This was the most useful video I found and probably saved me £100s in callout/plumber charges.
I've not bothered, my punctured washers haven't appeared to have developed further pimples. They've lasted longer. Thus in my non statistically relevant sample size of 3, puncturing the washers improve their performance and are less susceptible to these 'pimples' than new washers.
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!
