Got some attachements in an email today, compelling inspectors to educate and call out un-bonded csst.
I stopped doing so in my area after a local electrician and KUB (the local gas entity) had a fit about a house I wrote up. They said it was dangerous and should not be connected.
This has never been enforced or mandated here. Next time someone complains, I will just tell them to argue with the state.
