I have a 100 year old house with knob and tube wiring throughout. I have read that K&T is safe as long as the wiring is in good shape and the splices are done professionally, which seems to the case in my house.

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.

Thanks Drew.

I would remove as much of the unused k&t as possible. Don't try to undo the splice. Cut off the branch and leave the solder connection. Tape over it.

Wouldn't capping & taping the cut branch be breaking code. I always thought the loose wire should be secured in a box that is accessible once the wall is sealed up. This is not an option for me since the splice is in the ceiling. That's why I wanted to undo the splice.

Also, any ideas if the wires being very tight is an issue or normal?

Thanks, Drew.

I don't know about the code issue but I was trying to say cut the wire off right at the splice but don't try to take the splice apart. This would leave less 1/8" stub that could be taped over as part of the original splice.

Good clarification. Thanks Joe.
