main supply line configuration

This '97 split level has the main supply coming through the slab. I can't decide whats going on here. Is that PE supply line being coupled to copper with a Fernco coupler? Or maybe the PE is a sleeve for a copper supply line?

What can you tell from the picture? The coupler was not straight inline with the PE portion, that's for sure. What is the concern here if any?

As you know, it's common practice to sleeve copper under a slab. I suspect they added the Fernco to eliminate the chance of underground water seeping out of the gap between the poly and the copper.

Is the point where this enters the home at an elevation below the meter?

Yes, the meter is about 4 feet directly above the connection you see in the picture.
