Geberit 816.418.00.1 Flush Valve Base Sealing Washer - Clear

Excellent project excellent service.

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.

After about 15 years, our cloakroom toilet cistern was leaking a little due to the flush washer having become swollen in places. It was easy to fix and apart from a screwdriver to turn off the water (at the service valve), no tools were needed.The main requirement is to check that the washer is the correct one.The steps are:(1) remove lid of cistern: some just lift off, I had to unscrew the button push(2) turn off water supply to cistern and flush to empty(3) remove flush mechanism: mine unclipped, some have to be turned anticlockwise(4) Pull seal to the side to remove - it is very soft(5) Replace with new seal and re-assemble parts, turn on water and testThe old seal was blistered and as temporary fix, I pricked the many blisters - what looked like water came out - and made the seal flat again.

Easy to fit and stopped water leaking back into the bowl

Product as described and delivered very quickly. Highly recommended.

It fitsIt works

The washer was supposed to stop the leaking water (from leaking down the back of PAN after flushing) . Sometimes it does but so did the original one . So I am not amused . I am hoping it'll "seat" in after a week or so .

I had water leaking past the flush valve into the toilet bowl, leading to the fill valve having to open periodically to top up the system. This is the obvious part to change and at first I was delighted to find one at B&Q for about £2. However it didn't cure it so I pondered what part to try next? Logic said it had to be this washer (I nearly bought a complete flush valve) so before I started changing all kinds of expensive internal components I thought Id just give a genuine Gerberit seal a try for approx. £5. Sure enough it fixed it! No idea why, superficially they are identical but sometimes I guess the original is best.
