A leak in my airlock?

[htims05]

I ferment in buckets using the grommet and the "n-type" airlock. My last two brew's I've noticed that the grommet ends up with a puddle on top of it.

I can't tell if it's moisture coming from around the seal of the airlock in the hole itself or out of the cap...sometimes there's foam up there but it doesn't feel like it's running down the side of the airlock.

Anyone else have this issue? Cause for concern?

That's just bubbles from star San coming out the vent holes. It happens all the time . I've noticed when I use distilled water in the airlock it doesnt do it .
