I put mine in last May and it is still in there tight.
I screwed mine in by hand and then wrapped it a couple of turns with a piece of cloth and tightened it lightly with a pair of pliers, just tight enough to where the N. K. Mole they mentioned in another post couldn't steal it.
It has stayed put all this time, and no leaks. It works good and looks great!
