Have a hose bib that needs to be replaced. Problem is it's tight and I'm
afraid if I twist it too hard something on the other side of the slump block

on and it's almost against the block. So what should I do?

Heat with torch to expand the metal
(bibb must be empty of water).

Then wrench off ... gently.
