Designed to prevent leaks caused by wear and warping, it offers an easy, cost-effective replacement solution that ensures your toilet flush valve maintains a perfect seal, saving water and avoiding costly repairs. ## Description Geberit flush valve won't seal properly and is constantly passing water into the toilet pan but there is no sign of an inlet valve failure, it could very well be that the base sealing washer need to be changed. Overtime as the flush valve is opened and closed, small imperfections tend to occur in the surface of the rubber washer causing the washer to be warped and not providing an adequate seal.

This was the only part needed to fix the toilet. The one that was bad had air bubbles in it causing the toilet to periodically leak, then stop. Took about 10 minutes, and job done! ### ⭐⭐⭐⭐⭐ This worked in our unkown toilet with Geberit valves in place of 170.206.16.1 *by L***N on March 3, 2020* I was told by Geberit that I needed part number 170.206.16.1 but thought I would take a chance on this as it looked identical. Happy to report its the same part.
