    Warning: This post may make some of you weep, gnash your teeth, and rend your garments.

    With that out of the way, I need to run a new buried propane line from the tank to the house. In the past (15 - 20 years ago), I have always used black pipe. Everybody I knew used black pipe. I like black pipe.

    Nowadays, I read that black pipe is the devil. Black pipe will rust and crumble faster than a politicians campaign promises.

    So, I could still use black pipe but wrap it and paint it this time. But, what is the best option now? PE? Something like this?: http://www.grainger.com/Grainger/buriable-gas/plumbing/ecatalog/N-a6l?op=search&sst=All

    The underground run will be about 40'.

    Yes, I am aware of dangers involved and I recommend to anyone who asks that they have all gas or electrical work performed by a licensed professional.

    Edited to add: We are in an extremely rural area. There is no code enforcement. Even so, I try to most of my own work to code.

    I think you answered your own question. Without a gas licensed you have little chance of being able to buy the materials that you need.

    If Grainger requires certs to purchase the Endot stuff, they certainly don't make it clear.

    Here Grainger does not require a license, but neither will the sell it to anyone who is not a contractor with a valid "resale tax" certificate.

    I didn't install it myself, but called my propane company to do it, but we had copper ran underground from the tank to my standby gen set, with it's own regulator, and then piped with black pipe after the regulator. cost about $100 bucks if i remember right. i'm pretty sure he used flared fittings on the copper lines too.

    Copper is an option. I think I have always been subconsciously opposed to putting something that soft in the ground to carry gas. That, and the supposed issues with high sulphur gas.

    The redneck side of me would want to run copper in (vented) SCH 80 PVC conduit. Cut my brain some slack. I spent all evening working with my wife on her new kitchen layout and my brain feels bruised now.
