Best way to replace outdoor spigot

Question

I have to replace a 50 year old backyard bib and I don't know if it screws out or if the faucet was originally soldered on the the 1/2 " tube.

What is the best way to approach this?

Below is a picture of the exterior view. The inside view is just the tube going into a wood sill board.

I haven't done any soldering in 20 years and I'm wondering if there's now an easier way of doing this project.

Should I just cut a 12" length of the existing copper supply tube and solder a new 12" assembly (faucet & soldered 12" replacement) and sliding it through the existing exterior hole and then soldering them with a copper union?

Or is there an easier way to join copper these days (ferruled compression fittings, etc.)?

Answer 1

If you have access, I would put in a new frost free (the valve seat is at the end of a rod.

This particular one allows you to thread it on, or solder it on. Lowes.

If you don't have a frost problem, this is still probably the easiest way to get the connection where you can work on it.

Note: Whenever I have to repair something, I also put in a shut off valve, figuring that if I have to repair it once, I will likely have to again.
