Problem is its started leaking from 1/2" threaded end, where it

If thats plastic it highly likely its cross threaded

or possibly cracked.

The toilet at my daughter's had a similar problem.
The last bit of the threaded plastic pipe had cracked.
Plumber cut it back to good plastic, fitted a new washer, and the leak was
cured.
[Just managed to save enough pipe to be able to refit the female connector.]

If there is no obvious cracking then replacement may be a good idea.

Most continental cisterns I have seen have a flexible connector for the last
bit of the pipe run.
This seems a good idea to me as it must reduce the stress on the ball valve
connector.
Obviously the 'stiff' pipe must be clipped just before the flexible pipe run
starts.

I often wonder why the 'continentals' do this and the Brits in general do
not.
