I will run a natural gas supply line from the meter to a 3 burner nat gas barbecue unit, the distance is 25'. Should I run 3/4 or would 1/2" be adequate? Best, Seamus J. Wilson

1/2" can handle at least 40,000 Btu If you are up about 70,000 or so, use 3/4"
1/2 will be more than adequate.
I'd run the 3/4. You only do the job once, and only pay for the materials once. But, someday you may want another appliance out thataway.
My big 4 burner BBQ is supplied by a 3/8" ID flexible rubber hose. It works fine
I don't think I'm allowed to tap at the meter. I can come out the wall from the kitchen with a gas line an run it 25' to the patio. It would be 3/4.
Ask the utility company?
See same from 10/30/2008. Answers, etc...

Is that a 25' hose?
What btu are burners total, Mine was 15000x3 plus a side burner of
10000 for 55000 total. Many are smaller, some are more. There are charts for pipe size, length, and btus that are easy to look up. If its 3- 10000 btu burners 1/2 might do fine.
Water is under a *lot* more pressure. Gas is typically supplied at a pressure of about 6" WC, which is somewhere around 0.2 psi. It's not unusual for the pressure in a city water supply to be four or five hundred times that. Even a low-pressure well system is at 100x the pressure of a typical gas supply.
