I have a problem with a leak from the supply pipe to a toilet that I
would appreciate some help with.

It is a problem at the in flow to the ball valve.
Initially there had been a very slow leak from the nut which I noticed
when I moved in. It was only a slow drip and could be easily
ameliorated by putting a trough underneath and turning off a stop cock
when if I left the place empty for a few days. One of those awkward
jobs that I could put off.
However, it got worse recently spraying a fine mist onto the wall
It is apparent that the cistern was replaced some time ago and the
plastic ball valve assembly had not been properly fixed into the
supply. Looking at it the thread had been damaged and this could have
been the source of the leak.
I got a new metal ball valve assembly and tried to fit it.
The problem is that I can't form a seal at all. As soon as I turn the
pressure on the water jets out of the back of the nut. (See the arrows
in the picture)
The nut is only hand tightened and I suspect was never turned at all
when the cistern was replaced because paint, which seems to have been
applied earlier from the decor of the room, came off. I doubt I could
tighten it much further.
Or am I wrong and this is the source of the problem?
The nut, by the way, turns fairly freely but does not come off at all.
What do I need to do?
