So we have had 3 plumbers come out and give estimates. One wants to use copper, 2 want to use pex. So now the choice. Several people have suggested HDPE, but that has not been offered.
But you know, we have moles in our yard from time to time and I have read that varmints chew through pex. What to do?
They would be using trenchless, directional boring equipment, like nealtw suggested, to go under the concrete.
