NK Porcelanosa WC Syphon seal/washer replacement

[kenwalker1945]

Hi. Water is slowly leaking into the toilet bowl from the cistern. I suspect that it's the rubber washer at the bottom of the tube that's the problem but I can't figure out how to get to it. I can feel it when I put my hand down to the bottom of the tube and it seems flexible but it's 16 years old so it could be distorted or something. I may have to call in a plumber to sort it out but If anyone can help I would appreciate it.

It’s a Geberit Impuls 280


Common issue for the washer to bubble as it was made in two parts updated one is silicone single part

You were certainly right about the bubbles, Shaun! Many thanks.
