I noticed that my spigot was leaking. It was only leaking out of the hole where the water normally comes out. I made the mistake of slightly tightening the packing nut without having another wrench to hold the spigot in place. Now the original leak still exists and I now have a very slight leak coming from behind the spigot. Wonderful. Thankfully, I have a separate shutoff valve for the two spigots on my house. I shut it off to prevent any more leaking while I try to figure this out.
I'm guessing that the new leak is due to the soldering joint cracking whenever I tightened the packing nut. I honestly didn't put much torque on the packing nut. I'm surprised that the soldering cracked due to this. I've taken the spigot off to take a look at the pipes coming in. I've got pictures below.
The problem is this: I'm on a slab (it's a townhouse). The spigot has an immediate elbow since it is right behind the dining room wall. What should I do here? Should I make a hole in the dining room wall to have access to this? I'd love to avoid that if possible. Should I remove some of the hardie board on the exterior so that I can possibly get enough room to solder a new one on? Is there some other solution that doesn't require soldering?
