2 X Replacement Silicon Clear Washers for Geberit Flush Valve Base

After struggling with a constantly slow running concealed cistern toilet, I bit the bullet and decided to have a go at repairing it myself. Having watched several YouTube videos on the topic, I managed to dismantle the mechanism and narrow the problem down to a silicon seal attached to the flush mechanism. I identified a suitable replacement on Amazon, ordered it and the next day a package arrived containing 2 seals. I immeaditely got to work replacing the worn seal and reassembling the mechanism. The replacement seal fitted perfectly and to my amazement did the trick, no more running toilet. Job done! This small seal saved me the time and cost of calling out a plumber. Something so simple, I will now keep a couple spare seals as I think it is the lime scale in the water that caused the original seal to harden and fail over time (3 years!).

This item was a lifesaver in saving water, saving money (by not having to call a plumber) for a leak in our Geberit flush valve which I had assumed to be broken/leaking All it needed was an exchange in this washer to stop our toilet leaking Worth every penny on the purchase

There is only one washer per pack so don’t waste time trying to separate into the two shown in the lead photo. Does the job.

Cheap at half the price as B&Q quoted £22 for one, it works perfectly, fits perfectly.

Sadly these would not fit the cistern so are being returned they appear very sturdy but would not flex to fit the flush. They have been softened using boiling water but would that weaken the ring and make it less durable so this was not attempted Shame as they appeared good value for money

Used for geberit flush mechanism. Original one was 7cm , this is 6.3cm. fits well and reduced the leak significantly but there was still a small leak even after changing. Ideally should get the 7cm washer for better outcome I suppose.

Does what it says on the tin .Makes an excellent seal..

I was not aware there is more than one size of these washers. These ones I ordered did not fit and so were not used. For the price it was not worth returning them. They looked like they would do the job in the right size unit.
