Hello all,
The water supply from my water meter to the house is rubber pipe, but my water lines in the crawlspace are copper . Is it code to have a ground wire from the main electrical panel to the copper lines, since there is no metallic pipe to the house, which would provide a ground source? Currently, there is a #4 that does connect the panel to the copper pipes.
Possibly a ground is necessary in case of a lightning strike that finds the copper pipes in crawlspacex or the metal hose bib on the outside of the house.
The reason this came up is that the section of pipe where the ground is attached to has been replaced with pex thus ending the ground. I have to extend the #4 another 8 feet to connect to the copper again. Which brings up another question. Can the #4 ground wire, per code, be extended 8 feet using a split bolt or is a irreversible connecter need to be used?
Hopefully, this is the correct forum and method for DIYers.
Thank You
Jeff
