No grounding on any of these flex fittings. I’m looking for #6 copper from fittings to panel. None grounded. Pics included. What’s the call. Water heater should be hard piped ? Should I check with municipality ?
No need to check, the older CSST and is prone to arcing damage. Write it up if it’s not bonded.
Also CSST can not be properly grounded/bonded via the water heater.
