I am going to add a short run from my main inside gas line to service a new cooktop. It will only be about a 10 ft run...the service line is in the ceiling a little over from the range location. Question is...do you normally test the new line from the meter to the rest of the system...and what is the normal pressure in an inside gas line (black pipe throughout)...looks linke am 1" or 1 1/4" run ?
I used to work for the gas company in Chicago a long time ago when I was out of school for awhile...we laid...welded...and tested hundreds of 2" lines in the time I was there. I would rather pressure test than use the old soapy bubble test.
Any additional help/guidance will be appreciated.
