ShoeMaker's Children Eh ! Joking aside, those fitters should have had their licenses lifted.The world is starting to wise up to the scale of the LEAKS involved with NG extraction and distribution... Something I can see turning out to be a source of emissions as big or bigger than the actual use of NG. At my old job we bought a building that had been occupied by a company that specialised in gas fitting, initially the place absolutely stunk of gas. We had to get a gasfitter in three times to fix all the leaks we found.
I'm not big on incompetence, in any industry or trade.....
