My vertical nipple was leaking too but it was leaking from where the cap and nipple meet. I took a rubber band and wrapped it around the part that was leaking and no more leaks! Try that and see if that works. The leak was driving me insane at first.

I used white teflon tape to seal the horizontal nipple, no leaks, no problems. The vertical nipples I had a 10 pack so wasn't worried about reusing it - I sealed that sucker in with gorilla glue. Way overkillbut definitely no leaks.
My chicks are just messy drinkers from the vertical. The horizontal nipple they went back to ignoring after a day, they might use it if I took away the fast flowing vertical nipple but the drips are contained to the scrap 1x4 board underneath it so I'm not so worried about It anyway.
