Grounding plastic water line?

[JKinPA]

It was suggested that I ground the water line where it meets the pressure tank. The water source is a well which is completely plastic pipe. The only metal in the water system is a pex manifold, pressure tank, and hot water heater. Why would you need to ground the pressure tank? Can you count on the water in the plastic tubing to make a connection to the well casings? One other point I might mention is that there are already 2 ground rods.

You only need to bond a metallic water system. Isolated metal sections of pipe or components do not constitute a system.

You need to bond the pump as per 250.112 (L) and the well casing as per 250.112 (M)

Is your pressure switch located at the pressure tank? Usually. You will need an EG to it.

I wouldn't know if I should red tag the plumber or the electrician on that one.

You should have used plastic wire, instead of copper. Red Tag!
