Due to a limited budget, I have chosen to leave most of the K&T intact and simply reduce the load on the K&T by adding new circuits where needed. Here are my questions...
1. Some of the K&T wires (running through the floor joists) are pulled very tight. Is it customary for K&T wires running through joists to be tight? If not, is there anyway to correct this (add some slack)?
2. One of the areas where I added a new circuit was the bathroom. Now my dilemma is what to do with the live K&T in the bathroom walls and ceiling. Should I leave the wires in the walls and just cap them off in a box? Or should I remove the K&T branch from the main K&T run? If removing the branch is an option, what are the options for doing this? Note, I have access to the splice in question which seems professionally done and wrapped in electrical tape, but I have heard that these splices were soldered together back in the day in which case I wouldn't want to mess with it.
