My house is currently only grounded at the panel, but not at the receptacles in the home. I was all set on purchasing my PEX supplies here shortly for my home run system, but my retired electrician neighbor, who has been against me going PEX from the beginning, finally came with argument that's making me reconsider. Eventually I am going to ground the home, and I won't be able to tie to old galvanized or copper pipe because it won't be bonded, so I would have to run a line from each directly to the panel, making the job that much more expensive. As I was writing the post it occurred to me that I could go copper for my line in to just under the wall where my manifold will be, and then run a PEX riser to the manifold. Will that fix my issue?
