The elbow is under the floor joist, for hot water, in an unfinished
basement. Easy to check up on and easy to re-repair. Curious to people's
opinions on whether this type of repair is considered permanent or not.

I've yet to use a SB fitting. They are on my options list.

In your case, you can observe and monitor the fitting from the
basement. I'd not worry and consider it permanent -- until it fails.
I'm hoping they are permanent - one is under 6 inches of concrete,
and another above and behind furnace duct and finished basement wall
and ceiling.
