Most laws say 12” either side of the line is the protection zone. So +-3” is
plenty accurate. If only they were all that accurate.

How big of a pipe would it have to be for that to be a concern? I would think
~3 inches of variance is within the spec of the locator.

stand over them when theyre putting it in to make sure they dont just
randomly toss it in the open trench. you dont want it toning out at a different
depth/horizontal because it coiled up. especially if theyre doing a wide trench
excavation.

We specced safe-trace with 1800lb pullback strength for our current project
and will likely makenthat the standard for anything drilled in moving forward.
Not sure it is overkill.

14 gauge is rugged and will last. I think the gas company out here uses
14 gauge. 20 gauge on up is not terribly strong. UDOT recently changed their
spec for the tracer molded into MD7 microduct from 20 gauge to 14 gauge.

Don't you have some random copper laying around? Our fiber tracer wire
is 24 awg. Just place the conductive wire in the same hole as the water/sewer
lines. The color is kind of pointless but I guess you could spend the money
and follow the rules *shrug*.
If the wire ends the locate ends. Why not just extend the wire with the
new pipe?
14 gauge seems like way too big if you ask me, that's a lot of money down
that new sewer line.

I'm working on doing specs for a project (home) which will require
burying new water and sewer lines on the property.
I'm tired of not being able to locate these after they're buried so I
plan on having the contractor bury some tracer wire along with the plumbing.
I've learned that the best option for things like this is to either
spec or provide exactly what I want buried. Otherwise you'll end up with some
inexperienced contractor which installs something which won't work.
Apparently the choices for tracer wire are far more varied than I had
expected. Insulation, metal type, gauge, color, and so on.
It looks like 14AWG copper HMWPE might be what I'm looking for. But
there are other options as well. Does any of this work better or is less (or
more) likely to be damaged in a way which makes it untraceable? I'm assuming
green and blue will be needed for sewer and water.
I don't think the following will apply, but there is also the
possibility that at least one of the lines won't terminate at one end anywhere
that we can poke the wire up above the ground (tapping into existing line) I'm
assuming that one can resolve this by laying a ground rod in the trench and
terminating to that.
Any other things I should watch for here?
