Recently, the gas company run a gas line from the street to the house. The
line is no more than 1/2 an inch. Now, from the gas meter to the inside of
the house, can I use a 1/2 inch pipe? Or is the gas at higher pressure up to
the meter and therefore needs a bigger diameter?
You need to run a 3/8" main throughout the house and branch off to
each appliance with a 1/4" line.
Leave your gas line the hell alone because with the question you just
asked you dont need to be anywhere near a gas line.
Depends on the pressure. If you have a 1 or 2 lb meter, at least in
my area, small diameter tubing can be run to all the gas appliances,
provided each appliance has a regulator to get the pressure down to
the proper pressure for each.
BUT - If you have to ask the question, you shouldn't be messing around
with this stuff yourself. Get a licensed, experienced tradesman to do
