I have seen installations like this for an exterior faucet that does not have room for a non-freeze type. You turn the water off on the inside and let the faucet drain on the exterior.
Maybe but it looks to be only 1/2 " with 3/4’ going to the water heater. That wouldn’t make sense for a softener install. JMHO

Thanks for your thoughts, fellas. I like the hose bibb idea… there is a bibb perpendicular to this curious arrangement, just follow the wall about 20’ to the intersecting exterior wall and there it is. Distinct possibility there…
Yes, it was 1/2", so with 3/4" servicing the water heater it didn’t make sense for it to be the unit shutoff.
If it’s not the bibb than maybe it is for a possible water softener… or something else, but what?
Seems the best I can do is call it out as a question for the condo assn…
