Good advice. I'd add: put a chafe collar on the ends of all conduit, a
standard pvc conduit part (also code on 3/4 and larger IIRC). The sharp
end edge of a conduit can slice thru cable insulation. Another
advantage of using mule tape or conduit measuring tape as the pilot is
exact length measurements of the conduit as installed. One calculated
length I used was much shorter than actual and resulted in only 1' tails
- ouch but better than -1' tails.

Depends on what you're pulling, how big the conduit is, how many
bends, etc. In worse case scenarios I avoid knots of any kind in the
pull line. I stagger the cables being pulled and simply tape each
cable to the mule tape with generous TIGHT wraps of electrical tape.
I'm not afraid to use a whole roll or two of tape, and a fair bit of
time preparing the mass of cables. I'll cut the ends of the cables at
an angle to lessen the chance of catching on a conduit joint. A little
cable lube helps.
As you probably noticed muletape is commonly available in 1250 lb and
2500 lb strengths (and stronger), so it's good for pulling fairly big
bundles of cables thru hundreds of feet of conduit with a capstan
winch. If you try to do this with twist rope you'll melt PVC 90° bends
almost instantly.

I have always used #14 solid wire for a pull rope and once it was pulled

never
heard of Muletape until this post. It definitely looks like it would
make a
very strong pull cable, how do you attach multiple wires to it?
Muletape is the only thing to use. It's flat & slippery, does not
tend to
twist, and won't burn thru your PVC corners. And cheap. And strong.
