I would cut it off and install an Anti-Siphon Sillcock Frost Free Outdoor Faucet. It will save you any headache.

>> as it burst previously in 2021.

You'd think the plumber who fixed it the first time would have replaced it with a frost free spigot or at least a shutoff with bleeder on the inside of the house. Guess he wanted to keep you as a customer for the next year.

Yeah, my suggestion wouldn't be applicable then. Good luck.
