Answer 1

  There are too many unknowns to answer your question accurately.

Such as, how far are you running this line, and to what are you running it? You would need the distance and the total BTU load to size the line properly. Is this system propane or natural gas? Is this in a high or low pressure system?

  Polyethylene tubing is the product of choice for underground lines, and yes you must be certified to install it, and yes it requires specialized tools to install.

Black pipe underground without cathodic protection, will eventually rust and leak regardless of how well it is wrapped. In some areas it is now illegal to install steal pipe underground without true catodic protection through induced current, or self sacrificing anode.

The only way I could suggest that this would be a do it yourself type job would be if you were using copper tube on a propane installation, and you were running a line across a yard to a garage for a small heater or something similar. You could then consult with your propane company regarding the proper tubing size, and trench in the line yourself to the legal depth in your area. Then you could have the propane company come out and pressure, and flow test the system.

In any case consult your gas company, in many cases there are things that you can do yourself to save some labor charges, even if it’s just having the trench prepared.

Answer 2

I agree. Gas is extremely dangerous to try yourself. A lisenced plumber is a very smart idea.

Answer 3

You DO NOT want to mess with gas.  Call a licensed plumber and get the job done right, with permits too.
