Ok firstly there are DIFFERENT TYPES of Caroma Cisterns. Everyone tells you "just pull out 4 tabs" Well mine and many others DON'T have 4 tabs!!
Secondly they don't tell you there is no need to "remove the valve float arm that BLOCKS the obvious removal of the plastic assembly." you work around it.
In mine it had 2 side "tabs" the same pink colour as the square surround. It turns out they CAN'T be pulled out...
I read everything on the web and a video (all useless) that avoids the hard parts and things just miraculously appear or disappear!!
Finally after trying in vein on my own for ages I got mad at the whole f'ing thing and pulled so hard it feels like you are going to break it and presto, it is just designed to be pulled out.
There are NO TABS just locking notches on some models.
Next you have to lever off the slot off the middle plunger. Then after trying to lever off the bottom centre of the plunger to replace the washer one realises this isn't going to work you need to pull the old one off and stretch the new one on.
Simple when you know but no one tells you..... Companies like Caroma should web publish simple instructions for all their different products and save us all some grief. Simply retarded that they don't.
Pray for some intelligence in companies writing DiY manuals
Anyway Peace Bliss and Blessings to all this Easter
