Geberit flush mechanism seal Ø 58x32 – Ref 816.179.00.1 – Exposed and concealed cisterns AP025, AP125, Twinline 8

I have listed here the 3 symptoms requiring replacement of theGeberit sealing gasket:

1st symptom: Small bubbles form on the surface of the seal. These bubbles may look like a small blister on your hand. Their random placement interferes with the seal and causes a leak into the toilet bowl. This phenomenon is a defect. The only solution: replace the seal.

2nd symptom: The seal is whitish. The true "color" is transparent/opaque, but over time and with wear, the seal turns white. This condition is often accompanied by a ring of limescale that hinders the seal. As the seal surface is altered, limescale adheres more quickly, causing more regular leaks in the bowl. I advise you to replace it if you discover it in this condition.

3rd symptom: The gray seal ref.: 816.418. This reference is part of a black series from Geberit. It bubbles much more than the others, as in the first symptom. I do not recommend keeping this seal, even if it does not yet have bubbles.

By purchasing from my store, you reward my experience and my video content, thank you 🫶
