How to remove toilet outlet valve

[Arron]

Hi. I have a toilet which is slowly leaking water into the pan. I’m assuming it’s probably just a seal on the outlet (flush) valve that needs replacing. I can’t see how to remove this style of outlet valve and don’t want to use force. Can anyone tell me how it should be removed.

It’s a close coupled caroma but not sure if the outlet valve is original.

Cheers

A lot of flush valves rotate and come out as an assembly of the seat like the link below

Yep as above, slight anti clockwise click and lift out
Mark L and R on top in case you manage to put it back opposite to what it came out which will change the flushes.
And make doubly sure the new washer is fully seated or it will never stop leaking.
Washers readily available from local plumbers supplies, no, not bunnings, they only sell overpriced replacement washer kits that usually don't suit.
And once it is back in make sure the inlet valve is shutting off not overfilling and running out the centre overflow.

Thanks guys. With the confidence of knowing I was doing the right thing I was able to get it out fairly quickly. The odd thing is that there are a couple of little raised lumps on the seal. You can see them in the photo. There is nothing on the mating surface that they could relate too. Should they be there ?

Had one like that last week had air bubbles in it from delamination
Might be same problem.
Otherwise no idea.

YEp, poked a pin in them and they deflated completely. Oddly they were full of fluid, not air, but obviously just delaminating occurring.
Thanks

you can say that again and again and again and again, i dread doing these seals, they are a pain in the ass to get right and stop the leaking, sometimes i get them first go half the time it takes several goes for aligning it.

LOL yea makes sense to have water not air as the flush washer is under water all the time.
TBH I took one quick look at the bubbles and dropped the washer in the bin.
Didn't even think when typing just quickly somehow assumed air bubbles.
Must be getting old or spending too much time in the beer garden or both.
