Replace polybutylene supply?

[OneStaple]

Hey,

We moved into our house (built in 1986) a year ago, and a couple months ago I was on here trying to figure out what material the supply line coming into my house is made of, given that I could only see about 8" of it with no markings before it transitions to copper.

I was helping a neighbor with plumbing yesterday and was able to snap some pictures of their supply line, which looks the same as mine. Of course, the label on the pipe was pointing toward the wall in a hard-to-access corner, so it was hard to get clear pictures. But this is what I pieced together from the label on the section that was visible (with some X's for unknowns):
D6XX VANGUARD PLASTICS SERVICE BLUE 1" CTS-OD 250 PSI 73F WATER SERVICE ASTM D-2666 NSF XX

The ASTM number could be D-2666 or D-2668. The NSF XX almost looks like an emblem in a box. Based on the ASTM number (assuming it's 2666), this appears to be polybutylene.

In my house, this is the main supply coming through the basement slab on the front of the house. I assume it runs straight to the water meter and valve about 25'-30' away in the front yard.

What would you do at this point, knowing that PB typically fails, and often catastrophically? I assume it's worth calling out a pro to bore a new supply line rather than waiting for it to fail. My understanding is that insurance won't cover the replacement, but might cover damages if it were to fail, but that just becomes painful for everyone. So it seems better to do a preventative replacement, is my guess, and the cost will be my responsibility. If so, any recommendations on replacement material and guess on cost?

I'm attaching a couple pictures. The one with the label on the pipe is my neighbor's. The one showing the blue pipe coming up through the slab is mine.

Thanks,
Tyler

I would ask the opinion of the town water department. They might have experience.

I think the main failure rate was due to the chlorine in the water.

Is the piping before the meter or after the meter?

It's after the meter and before the main shutoff inside the house.

I can't tell what the pipe material is before the meter since it's buried.

While I can't see it, I just found records from our water company stating that the feed on their side of the meter is copper.

It seems like the path forward is replacement. Any recommendations on best material for replacement (I assume they'll need to bore a hole) and ballpark cost?

fyi: that white PVC dresser coupling from the photo is a major risk for blow-out if indeed it has nuts on both ends.

Here's a better picture of the coupling, and it appears to have nuts on both ends as you referred to. Is that more risk than the PB line? And I should look to replace both in the near future?

Thanks,
