Home built in 1983-slab foundation-plumbed with copper tubing.

Problem: The copper tubing in the walls develops pin hole leaks, we are told caused by stray voltage or electrolysis in the water. Inside of inspected copper tubing indicates a small narrow groove cut in copper and moves to a point where a pin hole leak develops.

We are doing a complete re model and need to know what the best product is for a complete re plumbing to releive this problem. Should we use copper (and ground it), CPVC or what? We want a permanent fix this time!

the fact is concrete and copper do not mix. Any lines that go thru the slab should have been insulated. Insulate the new copper thru the walls and use what we call bunny ears for supports.
