    The screws are tamper proof so HO don't mess with them. As for the copper, there has been a long on going debate because at on time copper was believed to not be compatible with the odorant in natural gas.

      is it the odorant or the sulfur content?

        The odorant is Mercaptan which is a Sulfur Compound so by default it would be the Sulfur. There are a lot of studies now that seem to clear the odorant from damaging copper. I am not convinced just yet.

                very popular in the older neighborhoods. for some reason they don't surface in copper. seems to have made a transition at the riser.

                even stumble across pvc gas mains from the 70's. especially for pool heaters.

                  I worked on a job many years ago where all of the gas was run in hard copper under the slab.
