We've got piped-in natural gas and I'm tempted to convert my little
generator to use nat gas so, in the event of an extended electrical
outage, we'd be covered fuel-wise and be out from under the issues
around storing gasoline. The alternative being a large propane tank
or a number of smaller propane tanks.
But it's 50' from the house to the garden shed where the gennie lives
and we're on a shale ridge - i.e. running the plumbing underground would
be quite a task. I'm thinking close to a grand to get somebody in to
dig the trench and run the pipe.
OTOH, I'm wondering if I could just have a natural gas outlet installed
on the outer wall of the house and, when the need arises, uncoil 50' of
the right kind of flexible hose to feed the gennie in the shed.
I'm certain even w/o looking it wouldn' meet any Code in existence.
Too spooky even for me; the possibility of something catching on an
exposed piece of NG tubing is just _too_ much to contemplate given the
potential result. If needing the generator means likelihood of bad
weather that means possibility of an induced failure besides manual
What's $1K compared to replacement cost of the house...have somebody dig
the trench; you can do the rest of the labor/install if you're that
concerned over cost.
The only way I'd even consider something other than that would be to
have a humongously strong and clunky protective barrier around the
feed...and even then don't think I' consider it long.
$0.02, etc., etc., etc., ...
You may want to check the local codes. Gas can be above ground, but
it may have to be black pipe, not flexible.
6.1 Plastic Piping Materials
Plastic pipe, tubing, and fittings used underground shall conform with
the Standard Specification for
Thermoplastic Gas Pressure Pipe, Tubing and Fittings, ASTM D2513. Pipe
to be used shall be marked GAS
and ASTM D2513. Plastic pipe or tubing shall not be used for gas
piping inside or beneath buildings, or
outside, for above ground applications. Plastic pipe or tubing shall
not be used for venting gas pressure

If it's temporary for use in a power outage, IDK what the codes
say, but they certainly sell long lengths of gas hose for use
by RV folks and such. I even know someone who's bought about 25 ft
length for a portable barbecue. Here is one place that sells them....
But, don't you also have to then run power back from the shed
to the house? How about some kind of small utility type shed
close the the house, nat gas, electric inlet, etc and keep the
generator in there?
The only issue - when did you last price 1 inch or larger flexible
gas hose??? To run my 9000 watt genset on a 25 foot hose it needs to
be 1 inch.(or so I'm told) and the longer the hose the bigger it needs
to be to handle the same flow at the low pressure they run.
So I'm debating running a bit more hard-line so I need less hose -
mabee get away with $200 worth of hose.

Looks like it;s $580 for 50 ft of 1"
That plus other reasons would have me looking at some kind of
small utility storage box/shed large enough to hold the generator
near the house/gas lines, etc.
I've seen plenty of gas line(pipe, not plastic) run outside, but
always along side of a building with supports attached to the
building. It may be possible to run pipe but probably mounted to some
sort of supports and possibly with a protective barrier.
It maybe cheaper and easier, and safer, to pour a pad and make some
sort of shelter for the generator that is closer to the house. There
are still regulations as to location.
Above ground natural gas piping is pretty common in my area.
It's along fence lines by the county road ditches. It looks like
ordinary black pipe. This pipe was put in by the gas company. I guess
they put it underground where there was no fence but over ground
where there was fencing.
That's where I was going in the first place - until the thought of
above-ground came to mind.
Actually, I thought it might be *less* hazardous because a leak would
just dissipate into the air instead of maybe running along the
trench/side of the building and maybe into the building - which seems to
be the situation behind the few natural gas explosions in our area that
I have read about.
I would not be comfortable moving the gennie closer to the house because
of the possibility of carbon monoxide poisoning.... nasty stuff....
So I guess, once I verify the cost, it's back to my original scheme of
storing/using propane in or behind the shed.
