Gas line from meter to interior of home

[Kerri L. Grabowski]

Can a gas line from the exterior meter to interior of home be buried under soil or grade level deck or in contact with soil? Line is galvanized.

I suggested that it be re-routed...

[David P. OKeefe]

Why not? Isn't the gas line underground from the street to the meter?

[David P. OKeefe]

But I must confess , I don't recall seeing a gas line from a meter to house going under ground.

[Kerri L. Grabowski]

Then why is it 99% of the time you see gas lines FROM the meter to the interior of the home above grade?

[Larry D. Kage]

It depends on what is being used. (Galvanized is a no go.)

2003 International Fuel Gas Code:


404.8 Protection against corrosion.

Metallic pipe or tubing

exposed to corrosive action, such as soil condition or moisture,

shall be protected in an approved manner. Zinc coatings (galvanizing)

shall not be deemed adequate protection for gas piping
underground. Ferrous metal exposed in exterior locations shall
be protected from corrosion in a manner satisfactory to the
code official. Where dissimilar metals are joined underground,
an insulating coupling or fitting shall be used. Piping shall not
be laid in contact with cinders.

404.8.1 Prohibited use.

Uncoated threaded or socket

welded joints shall not be used in piping in contact with soil

or where internal or external crevice corrosion is known to

occur.

404.8.2 Protective coatings and wrapping.

Pipe protective

coatings and wrappings shall be approved for the application

and shall be factory applied.

Exception:

Where installed in accordance with the manufacturer’s

installation instructions, field application of

coatings and wrappings shall be permitted for pipe nipples,

fittings and locations where the factory coating or
wrapping has been damaged or necessarily removed at

joints.

It’s done here in Southern California, I see natural gas meters next to street or edge of property line (some in vaults and some not) with underground supply lines to home quite a bit. Of course you want to check with any requirement or codes regulating running a natural gas line in your area.

Good Info Marcel:

I am not sure what kind of line you are talking about so just to be sure I am adding this.

Gastite

®/FlashShield™ CSST shall not be buried directly in the ground or directly embedded in concrete (e.g. slab on

grade construction, patio slabs, foundations and walkways). When it is necessary to bury or embed
Gastite

®/FlashShield™ CSST, the tubing shall be routed inside a non-metallic, watertight conduit that has an inside diameter

at least 1/2 inch larger than the O.D. of the tubing (Fig. 4-85). For ends of the conduit installed outdoors, the conduit shall be sealed at any exposed end to prevent water from entering.
