Thank you so much for this video! I had exactly this problem and the plumber gave me a quote of 170€ to repair it but with your Video I managed to replace it myself and it just cost me 30€ with the replacement part ordered from Amazon 😊 you saved me a lot of money - thank you so much!!

Also for those attempting to fix it themselves a little tip: I had to replace the entire thing but in my model the black ring was not in the cistern but the water tank underneath it. I was still able to screw it on without taking that bit apart by fishing it out and kind of making it stick to the opening, maybe because of the water suction it stayed in place (while I said a prayer so it would fall off) and then I very gentle screwed the new part on. It seems odd that this worked but it did! It's now all fixed and there is no more leaking into the bowl.

A very clear and well explained solution to my Roca toilet problem. Spot on

Have a Geberit and completely overhauled the thing. Removed both float and flush mechanism. Cleaned, replaced plunger/float seal yet missed that darn silicone seal. Took it apart again (!) and popped the blisters and done. Thank you for your help, saved me $300

Great video, helped so much and my toilet is working again. Anyone can do it! I've just done it at 03:30am 🤣

Thank you I saved money thanks to this video.

Thank you very much! After dismantling my Roca water tank and everything looking in order I watched your video where you say the magic words "flip the seal". After doing that the problem was fixed! ❤

Will my wife be able to use her toothbrush after?

Perfect. I was a bit sceptical about my ability to fix this problem but I followed your instructions and in less than half an hour it's in service again. Many thanks

Thank you very much, showing how these may be taken apart and cleaned was most helpful, and indeed solved the problem. kind regards to you. best wishes Simon.

Great instructions. The washer had an air bubble in it which was causing a slight leak. When I went to buy the washer, the guy said that if I had just popped the air bubble the washer would work again.
