> [@canderson5](#): > > Mike, why not be helpful and post several sites you personally would reference regarding the dangers with CSST. I for one would not call it out as junk based on your opinion. You seem to have studied it, share your findings. It is a little lengthy but it is good. Towards the end are some pictures.

It will be interesting to see if this is CSST related. It would have nothing to do with bonding/lighting…but.

Well… The gas company governs SQUAT inside your house. If the gas line is likely to become energized then it gets bonded. If section 250.104 takes care of it then done. ---
