Hmmm bit of a bore, this one!
Assuming you have a typical plastic valve by Opella / Delchem or whatever.
The large round nut unscrews, and the float arm comes away with it, revealing the large shaped diaphragm washer that you have renewed.
Can you compare old and new, especially to check on the diameters?
The water in these valves comes out of a plastic spout on the top of the valve which unclips readily enough.
(Is that your 'blue tap thingy'?)
There's another plastic nut that can be undone on the remainder of the valve......that contains an 'o' ring and the tapered inlet nozzle - the thin end of which bares onto your new, replaced diaphragm washer. Thats all thats there, as far as I can remember - no fibre washer springs to mind!
Popular leaks with these are due to a) the new diaphragm being the wrong diameter b) the diaphragm is the wrong way round c) the key slot has been ignored (this keeps the assembly upright) and d) the nut isn't tight enough.
If none of this is any good, a pic would help, I guess!
