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.

The right way would be to buy a test gauge Pump the whole system up with a
bike pump only needs 10 psi for a couple hours. Put the gauge were the new
cook top will be. You will most likely have to shut of all the valves to any
gas fired equipment ( water heater Furnace ect.) You might be able to start
the additional line with a valve Make sure the valve has WOG on it ( water
oil gas ) then just shut that off test the additional pipe. It's always best
to soap all the joints as an extra precaution I always use about 5 wraps of
Teflon tape on the treads then use rectorseal ( pipe dope ) Just to be safe
you might leave the gauge on the line until your ready to hook up the new
cook top that's the advantage of an in line valve .
