Does this look right?
Did you check every fitting for a leak?
That is down right insane. Why didn’t they just supply runs with individual read outs for each unit. Let me guess the GAS company will not allow it.
Did you count how many are there?
3 buildings with 130 units each.
I do not like seeing that stuff sagging in front of a car entrance but it is considered acceptable if indoors and not underground.
I have not found any rules on securing.
I saw no problems with the photos.
Where do the electrical bonds terminate? It has to go to the system ground bus or ground rod…not to a separate ground rod.
Did you check to see if the bonds were clamped tight? They are often loose.
