DYI thaw frozen line

[joeryan80481]

They have a wellhead about 75 yds down below their home and it’s been diagnosed that their line is frozen. No water for 2 weeks. The line is plastic and are looking for any DYI ideas.

DIY ideas (long shots...):
1. (long) wait until warmer weather
2. Pump hot water down the line (but yeah, where would they get hot water?)
3. Dig up the line and surround it with electrical heating tape to melt the ice in the pipe -- but digging 75 yards in winter probably not DIY.
The result of digging up the line could be to find that the line has burst and water's not getting to the house because of the burst line, not ice remaining in the line.  I suppose fixing the plastic pipe might not be too hard -- a new section of pipe and some pipe unions to replace the broken length.
