I have an old leaking spigot that I was trying to remove the value and replace the seals. I can't get it unscrew. I don't know what all my options are at this point. This is my first home and I've never dealt with this before. At first I thought I only needed to open the spigot value and then unscrew the nut behind it, but then I noticed it's the bolt behind the nut that connects to the base. If I continue trying to get it unscrew, does anyone have any suggestions on getting it off - sprays, oils? I don't want to snap the pipe and then have a bigger problem on my hands. If I should just replace the spigot, it looks to be soldered on from both sides. I'm not sure how to go about doing this. I've seen some Youtube videos, but most of them are (best-case scenerio) very straight forward with clearance to work with the pipes. To get the elbow picture (attached), I had to cut out some drywall in a closet just to get to it. If replacing the whole thing is the better option, how should I go about it?
