I have this tap in the garage which is leaking at the stem. It does not appear to have a washer or it is seized and cannot be removed. If it needs to be removed and replaced, there is drywall near the solder and I am afraid of setting the drywall paper or wood studs on fire by doing any work there! See picture.Do you have any suggestions how to insulate the area so I can use the torch safely? I guess I could cut-out the drywall and expose the area as an option but not looking to deal with drywall and mudding to get it back together. I hate drywall work!
