Just in case you haven't dealt with this stuff before, here are the main ways Mr.Murphy can complicate things:
1) First, it's not unheard of fo the seals to have never been sealed. Oops! In that case, thank heaven, and simply pull out the bad wires. Then pack the seals properly.
2) Often the fiber dam fails, resulting in the mortar-like sealant running down into the pipe, and setting up in some low spot. Shovel time! You get to dig up the pipe, usually to the first sweep.
3) Other times the rigid pipe will corrode, with flakes of rust or collapsed pipe making a new pull impossible. A related problerm - which might be the cause of your bad wire - is when compacting and paving operations break (or crush) the pipe.
4) Often, there is not enough room between pipes for you to cut or thread the old pipe in place. Again, in that case, you're best served by digging down to the sweep, and working down there.
When you do finally getyour new wires in, do yourself a favor, and pull in a few extras; this will -maybe- save the day in the event another wire goes bad.
