Anyone know what's really involved in replacing a wire like this? In a
perfect world, there would be no sidewalk or other annoyances, I'd install
the wire in the appropriate pipe, there'd be birds and flowers and everybody
would live happily every after with free beer. But...ya know....

Water jet underneath the sidewalk using a piece of plastic conduit. Dig a
shallow hole on each side of the walk. Shove the conduit from one hole to
the other with water running, under pressure, through it. Easy to do where
I'm at in Fla. with the whole state being one big sandbar. Worth a try
where you are in NY.

Once through, cut off the 3/4" male pipe threaded nipple you added to
connect the hose to.


It's a sidewalk.. that's what, 24"? Dig a pit on either side,
and sledgehammer a chunk of 3" blackpipe across. Then
run 2" PVC conduit through the pipe. Don't use 90degree bends,
either use sweeps, or use 45 degree bends, and cross the
sidewalk at an angle.
