PG&E tells me to ask a plumber, so...
I have added some gas load and recalculated my new gas supply requirements using an example I found online, and the standard table for distance vs CFH to check pipe sizes. My meter will supply enough in total, so no problem there. Per the calcs, because of a 35 foot initial run to the first load, I know I need to increase my supply line to 1" from the existing 3/4", then I can size back down to 3/4 once the first load is out of the picture.
The table shows that a 3/4" pipe can supply 363 CFH at 10 feet from the meter (the meter can only supply 275; my total demand is 260).
The question: For convenience I'd like to tap into the existing 3/4" line about 5 feet from the meter, upsize to 1", continue the next 30 feet, then after the first load reduce back to 3/4. Can I start my 1" line 5 feet from the meter?
