Well then, my Gas Company are really on the ball, as this is what they used for my lines.
They took extra precautions in which I am grateful to them. (Them knowing I was a City Employee may have helped, as we service them also
Yes, I was amazed they put that much pressure through the lines, as a test, then told me they only put "ounces" through as a regular pressure. I asked them why they used to much, and they said they wanted to be sure!
I go by my own experiences on here an elsewhere, what I have done, what I have experienced and all the mistakes that I make so that others dont have to make them... (Sure wish I had something like this, when " I " was starting out! Then I would have saved thousands in mistakes!)...
Just my two cents for what its worth, and a wee bit extra for the collection plate
