We had a leak in our upstairs bathroom, about 2 weeks after we had a new ceiling put up and painted in the room below. It wasn't a major leak, but it caused quite a wide line to show up on the ceiling.
I've painted over the line 3 times now, but it just keeps reappearing, is there anything I can do to stop the water mark from showing up?

Stains will usually come right through a new coat of paint.
Did you prime it first? In my experience I've found that a good oil (or even better, shellac) based primer works best for keeping stains from bleeding through the paint.
