Gas line grounding

One of my mock inspections to conclude my certification was a property that was recently purchased. I thought this would be a good opportunity to check my work against another recent inspection. The previous inspector noted that there was no ground on the gas line coming into the home to fuel a water heater and it was in urgent need of correction. The gas line was plastic! The only metal fittings were adjacent to the water heater, likely for ease of hook up. Is there a need to ground the 4’ segment of metal gas piping when the rest of the line does not conduct electricity? What am I missing here?

What color was it?

The only plastic gas line I have ever encountered was the the line buried in the street.

Many inspectors nowadays will place narratives in all of their reports, because they have had that past issue with another home. The narrative then becomes standard in every report. Must have been a new inspector.

Methinks you may have misidentified the gas piping material. Perhaps it was CSST, which is a big deal if not properly “bonded” it would not be “grounded”

It was yellow

Corrugated yellow is CSST

Stainless steel inside wrapped in yellow plastic.

Thanks, you have prompted me to look further into it and it matches the description for CSST perfectly. Just read an article on the problems associated with the thin walled product. My friend was advised to run a copper wire from the gas line to the nearby water pipe. Proper bonding in your opinion?

Proper bonding of CSST

Is your friend a licensed electrician? If not than advise him to have a licensed electrical contractor do it.
Electrical work isn’t a game, and it must be taken very seriously. Knowing the basics of electricity, terms and concepts, as well as the basic layout of a home’s electrical system is just enough knowledge to be dangerous. There are thousands of specific and unique applications of electrical installations.

It’s great that you had the confidence to post it here. It’s the fast track to learning this stuff.

The person doing the bonding of the piping should be certified by the CSST manufacturer. They have a certification program. Keep the liability on the manufacturer and the installer.

Here’s a picture from a recent inspection for an example. Steel propane line was bonded after the regulator and before the CSST and back to the main panel
