How to remove flush unit from concealed cistern

Do the above just pull out, need to check it as its letting bye, access is tight so can’t see in , need to know I’m doing it right as it’s fairly blind access.

Looks like a bayonet style, click anti-clockwise to undo, then clockwise to re-attach.

The bottom half is removed bayonet style [its two parts]but the very bottom by black seal just looks round?

Ahh, then I’m not 100% on that. What’s holding it and water in place? Unless it’s a push fit into a rigid cistern and flushpipe?

I think it maybe, can just see small lugs on base ( in pic) that would clip into base . I vaguely remember struggling with it when I installed , 3 years ago.
Maybe someone else here can add, might give suppliers a ring to see if they can confirm fixing method before I start pulling at it.

Managed to dismantle, seems it just push fits into the base with the bracket at the top for the inlet valve holding it in place, only slts into the front half of the top of flush valve which may cause it to lean , poor design.
Re-assembled after a clean and though better still lets bye a little.Maybe able to just buy the seal, or its a new flush unit.

Hello,

I am in the very same position, valve is slowly leaking and need to either buy new unit or new seals (black & white seals) did you replace or buy new thank you.

Buy new is £27 and delivery to Ireland is £50 so would rather repair it if I can.

Seals not available separately, replaced unit.
