Hard water minerals have frozen shut off faucet. I have tried wd40, CRL can't seem to get it loose. Galvanized afraid I will break it.

I use stuff called " PB Blaster", you can get it at an auto parts place. It penetrates, and frees up problems like this. It works wonders on rusted nuts and bolts too.

When I'm faced with that problem I exchange my 14 inch pipe wrench for my 18 inch wrench. If the nipple comes out with the sillcock it can always be replaced when you install the new valve.. TIP: Replace the old nipple with a brass one to avoid corrosion. Good luck, Tom

You have good reason to worry about breaking off old galve threads, or turning joints further in the home. Is the line inside accesable? If it is, I would recommend having someone put a backup on the inside pipeing and then do as tom suggested, get a bigger wrench and break that puppy loose. Let us know how things work out.

Unless 1/2 inch was sweat directly into the faucet in lieu of using a female adapter to mate up to the male threads of the faucet.

Playing devils advocate here. Not intended to step on anyone's toes.

No problem,
You're entirely correct but I figure the OP knows the difference between threads and a solder joint. Ovruigo, welcome to the Plumbing Page. Stick around and contribute. Regards, Tom
