Gas meter connection and pressure

I am wondering how to connect the gas line from the house to the meter. Is there a special fitting? I am looking at increasing the pipe from the meter to the house from 3/4" to one inch to accommodate some new appliances that require one inch. Also, will my current meter be sufficient? thanks

Easiest will be to change the elbow that turns to the home to a 1 x 3/4 ellbow. Then run 1" into the home accordingly.

Dont know the CF of your meter and your btu load in the home to guide you.. Just call gas company...

I do this for a living...I install whole hose generators...

Also IMO best to leave a tee outside with a cap for future expansion for gen, or pool heater possibly.. Grill or fire pit...?

The line coming out of the meter towards the house is a 1" nipple -> 1"x3/4" elbow -> 3/4" pipe in the rest of the house -> 1/2" to each appliance.

lawrosa, do you mean the line can be 3/4" out of the meter and upsize to 1" down the line? Wouldn't the line need to be 1" straight out of the meter? I'm a little confused on how gas pressure works. For example the 3/4" that comes out of the ground and feeds the meter--shouldn't that be bigger than what goes into the house? similar to water supply lines getting smaller the closer you get to each fixture.

Not necessarily. The supply is at a significantly higher pressure, which is reduced by the pressure regulator immediately before the meter inlet. Depending on the supply pressure (most likely somewhere between 2 and 25 psi) that 3/4 inch incoming pipe may be able to supply ten times the amount of gas your house requires.

If you currently have a reducing elbow simply swap it for a regular 1-inch elbow.
