Making Connections “Gas-Tight”
Regardless of the grounding point you use, make sure the connections are “gas-
tight”—capable of retaining low resistance and integrity over time and with
exposure to the elements.
Use of an antioxide compound and proper sealing is essential. For protection
against corrosion, wrap all connections with Scotch® 130C tape.
Checking Cold-Water Pipe Integrity
If you’re using a cold-water pipe for grounding, verify the integrity of the ground.
In some cases, sections of metal cold-water pipes may have been repaired or
extended with PVC material. PVC material or a dielectric union will render a cold-
water pipe ground unacceptable for grounding.
