My guess would be that there is a release valve below ground that allows the water to slowly drain out. One place I worked at had a setup like that, don't know the correct name for the fixture but it too never froze
Why has this never frozen in at least the last 27 years? Nothing goes into the wall and there is a shutoff in the ground that has never been closed. I don't get it.

Crappie bite twice a day. 15 minutes before I get there and 10 minutes after I leave.
The two loudest sounds are a gun that goes bang when it is supposed to go click and one that goes click when it is supposed to go bang.
If you rob Peter to pay Paul, you can generally count on Paul's vote.
