Agreed, bad Juju. But when the owner gets the quote for install new
$$$$$, remove old $$$$$, haul off old $$$$, they almost always choose
the leave the existing in place.

I don't think this is a problem, just bad Juju. Quoted text from Ron
Fletcher: "I heard that we had the inspector scratching his head
trying to figure it out." How about the IT inspector? How about just
quality of workmanship? I used to be an electrician when young and I
was always the troubleshooter. Being young I didn't realize that the
more complicated the problem the job security I had, but rather spent
a whole lot of energy being peeved at electricians that abandoned
wiring and left it in place. You could spend days chasing wires to
nothing looking for the cause of a dead circuit. Being generous those
wires might be useful 2% of the time. Empty conduit buried behind
walls could be useful as freeway through inaccessible spaces but
abandoned wires were always the wrong color or size or insulation type
or.... Same with abandoned sprinkler pipe. It's just a scrap metal
bank that doesn't collect interest. If you don't need recycle it. If
it's not recyclable toss it. Leaving old pipe is like taking a dump in
your friends living room.
