Plumbing?

[BILLMCSE]

Digging and my detector goes off in the dime range. I start digging 2 inches, then 4, use pinpointer down in the hole and get pings but not close. Dig a little more and it starts humming. Find a light blue/green plastic looking band about 3-4 inches wide. Havent dug the whole thing yet but it looks like plumbing, not sure. It's a good 6 inches down. The band is going around in circle while inside the band is still dirt but the pinpointer is singing when I put it over the dirt. Looks like plumbing to me and I don't want to dig that up. Just wanted to get thoughts on if the group here thought it was most likely plumbing. I'm new to this.

Most plumbing should be below the frost line unless you're in an area that stays warm year around. Can you lengthen the dig to follow the plumbing a ways? People sometimes use PVC pipe to hide caches in.

I'm in Georgia so the frost line isn't that deep. Maybe I'll go take a picture and post it before I dig further.

Yeah I was reading that green PVC is used for sewer...nice.

Must be metal banding around it.

Years back when I landscaped, we were trenching an area and came across some underground cables that we ripped apart.

The cable company came out, did a repair splice and marked the splice with a large coil in event anything would go wrong with the splice, they could locate the spot with ease with a metal detector.

Not sure what it looked like but it was pretty shallow.
