Geberit 816.418.00.1 Flush Valve Base Sealing Washer - Clear

A tiny bit thinner than original one however fits perfect and quality feels like original one so no more leakage and weird sound from water cistern.

Some one mentioned the seal had something that looked like a blister , I attached a picture of what they meant , it stopped the leaking water into the pan and the noise . Worked well.

Delivery was next day, plus I had a word with a plumber friend and he told how to install it and it actually took two minutes to fit so simple and it's working fine now.

Genuine product and the new improved design

After many years service the flush valve in my toilet cistern began to fail, allowing water to continually run into the toilet pan. As with most flush valves it was likely to be a problem with a valve seal (soft rubber washer) not the flush valve itself. One quick turn, anticlockwise, and the valve was out revealing a rubber seal at its base that had a number of 'water blisters' on it. These blisters were the culprit by slightly lifting the seal and preventing a watertight fit. I simply punctured the blisters with a pin and replaced the flush valve. Problem temporarily solved, the valve shut off after flushing, as it should, with no water continually running into the pan. I found the required seal on Amazon when I looked up Geberit Flush valves (the name written on the valve itself) and for less than £2 I have now received and replaced the old seal. This has saved me £££s on a complete replacement valve when only the seal needed replacing, and even more £F££s had I called out a plumber to do this very easy task. It is also my understanding that these new transparent seals are not prone to blistering as was the old grey version. perfect for many years to come and well recommended.

Worked well

This is not an exact replacement for original Geberit flush valve sealing washer but it works. The original has a beveled side which fits snugly with the rounded base of the flush value. This one is flat on both sides.

Very good product

Passt

Old one had a few little raised bumps on rubber ( like blisters in/ on the rubber ) seal and caused a slow running leak . Replaced with these and took care of the problem . Perfect product and fixed in 5 mins .

The item has generit brand and product code on it. Fits perfectly on geberit flush valve type 250s. Lately I hv notice t toilet doing intermittent refill. Suspect t flush seal not proper hence leaking and refilling. There were 2 blisters formed on the old seal preventing the valve to close properly. The new seal solves the problem.

Funcionó perfecto, dejó de echar agua nada más cambiarla en un WC NK de Porcelanosa.

Exactly what I needed to fix my toilet tank leaking!
