Grounding wire, Copper Pipe, and PVC (lemmy.ca)

I have a grounding wire that is connected to a copper pipe in my house.

Originally, I imagine said copper pipe connected all of the way to the pipe which goes into the ground towards the well.

However, at some point, the previous home owners installed a filtration system and replace a lot of the copper with PVC pipe, so it goes Copper > PVC > Copper > Ground Wire

Is that ground wire still useful? Or do I need to extend it to where the original copper pipe extends into the ground towards the well?

A ground that is insulated from the ground is not a ground. So yes you will have to extend the ground cable to where the metal pipe goes into the ground.

It may be useful to bond metal fixtures inside the structure together and to mains panel ground/neutral for equipotential and fault clearing reasons.

Do you have a ground stake somewhere?

Not that I am aware of but I haven't looked yet, I'll see if I can find something
