Plumbing help, Hubby is scared to screw up.....

First, where is it leaking? You have an anti-siphon valve attached to the threaded portion, then the hose is attached to the anti-siphon valve. These leak all the time.
This is a quick fix, but you will need to drill out the brass set screw.

I'm thinking about a temporary fix, I use that spigot daily!! I will be going in from the inside, see if I can cut the pipe n the wall and do a frost free! I have a lot of plumbing/pipefitting tools of my Dad, a small pipe cutter will be used! I don't think randyt will be stopping by, but the coffee is pot is going!!

That's a quick connect on the threads. I really think replace the 47 year old spigot!! It has leaked for years, the pack washer has been replaced!
