I need to rerun all the gas line in my house all the way back to the meter, because the current size is 3/4 inch and the meter needs to feed a 1 inch to handle newly added appliances. The existing pipe runs through the concrete foundation wall 6 inches above ground.
What size hole should I drill through the concrete for a 1" diameter schedule 40 black steel pipe? How do I line/fill/seal the extra space in the hole after running the pipe? Do I need to keep the pipe from resting on the concrete?
