Have not tried removing from house
That will be next
I'm semi handicapped so I have to leave hose on as I can't get to faucet.
Will purchase new hose and use plumbing tape on BOTH ends.
Try hitting it with a hammer, sometimes its just enough to break the corrosion free, heating can cause expansion (try first with a hair dryer, than a torch). Sometimes turning it the wrong way clockwise slightly.
As Yogi Berra said, “It's tough to make predictions, especially about the future.”
It happened to me too. I followed a suggestion: use a Dremel with a cut-off wheel and cut a slit on either side of the aluminum fitting. Then you can pry it slightly and break the corrosion so the aluminum fitting can be unscrewed. It destroys the aluminum fitting so the hose is scrap but it's less expensive than installing a whole new hose bib.
