A lot of older plants in the USA use their water piping as their main ground for a lot of purposes. In one such plant, the grounding connections for the flammable liquid transfers were tied into the water piping. One day a water pipe failed and caused quite a bit of damage; the price to replace the pipe compared to the property and goods damage it caused. In order to make the repair in a “more timely and cost-effective” manner. So a large section of the plant’s water system was repaired using PVC piping rather than the previous “copper” piping. Would you do a MOC on changing the water (potable, non-potable, process, condensate, etc.) piping from a conductive metal to an insulator like PVC?
