Leaky Cistern

[Twofingertyper]

Hi all,

I've recently replaced an aging system with a push button "Fluidmaster dual flush with inlet fill valve" - and am having a bit of an issue with leaks, it's a close coupled toilet.

Am I right in assuming that, with the cistern not on the toilet, I should be able to add some water to the cistern and none of it should leak out? I'm trying to get this right before re-attaching to the wall (a right pain), it's not the main bathroom so I have time (luckily) and can now begin on something of a learning curve...

So, the water leaks from the nut that sits in the dohnut - but I've not got that far yet as I first wanted to make sure that it was all 'sealed'; the nut is tight but the water still drips out quite quickly, should I use something like plumbers mait here to help seal it off - or is there a common and obvious oversight?

Check that you have fitted a washer to the inside of the siphon/flapper before tightening up the backnut

And make sure surface between washer and cistern is clean and free from scale, grit and muck.

Syphon then washer then cistern then close coupler ( if fitted ) plate then back nut.
