How does it let water out but not gas?

I'm pretty sure Ed meant "leg" not "let"; it's just a collection point
that keeps the condensate/entrained water have a place to go out of the
main line into the appliance; not an automatic outlet.


Correct. Instead of an elbow at 90 degree turn, they use a Tee and the
bottom has a short nipple and cap. Traps anything moving in the pipe,
liquid or solid.

I take it someone has to milk the nipple every so often.

No, I've take them apart after years and found a little dust. Even on
industrial with 4" feed.

So it wasn't really necessary to have it there.
