| Jul 20, 2020 at 13:35 | comment | added | jwh20 | Water pipe grounding is no longer an acceptable practice because it doesn't provide a secure grounding point and, as you noted, the use of non-conductive pipes impacts that further. You should have a properly installed ground rod and bond the panel to that as required by your local code. I'm assuming you pulled a permit for the work you are doing, right? If not, it's time to get one. | |

Is it a metal pipe supplying the water? But yes, these days code requires 2 ground rod at least 8' (?) apart and connected to your panel's ground bar (or neutral) if not a sub-panel and neutral is bonded to ground there. | |
