I have a problem with a leak from the supply pipe to a toilet that I would appreciate some help with. You can find a picture at
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 c*ck 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 behind. 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?
