Poly Pipe Failures in a Critical Application

Used for gas service since the 1970's, poly pipe is not showing a perfect record.

Good grief, that looks like a CL class pvc pipe, for GAS? WTF... Not here, not even in FL are they that frigging stupid, older gas lines run in steel pipes, new ones in some sort of composit and must be yellow.

newer gas mains around here are fusion welded with plastic pipe 2" to 4" or so for mains. houses usually have 3/4" poly (yellow) with tracer wire. older homes have 3/4" steel pipe.

If they'd bury that damn stuff deep enough, I'd have no problem with it, though, how many gas (poly) installers water-backfill?

None if they use a plow.

If the soil isn't all-sand, I'd hope they trench for the line.
