My house is being renovated. Got rid of the oil and switching to
gas. Half the house has a crawl space, the other half is on grade
(with 10" floor joists). A new gas line will be run from the
street. The question is where to put the gas meter. My contractor
wants to put it near the side of the house adjacent to the crawl
space. Makes sense, but it would be unsightly. I want to put it out
of sight, which means near the side of the house without a crawl
space. This would entail running the gas pipe under the floor of the
house for about 29' until it reaches the crawl space. The contractor
doesn't want to do this because he doesn't want to end up with any
unaccessible gas pipe joints (i.e., burried under the finished
Question: is there some sort of code compliant gas pipe that's very
long (and flexible and comes on a spool), that could span the distance
I need without having to join multiple sections? How can I solve this
First question that pops up...Why not go around the house? Don't think I'd
want a joint in an inaccessible spot. A flex line and a one of those
trenchers that just cuts a very narrow line and feeds the pipe in at the
same time. No ditch.
Your gas co. will have ALL your answers.
THAT is the gas company's call. In our area, they no longer allow any
piping on the customer side of the meter to be buried, so all meters are
up next to the house when the line needs to be changed or on new const.
If I understand you, you mean that there is still conventional floor but it
is so low that it would not be possible to get under. There is flexible
stainless steel plastic covered gas line now. It can run the length you are
talking about as long as you do not mean literally buried in dirt or
Just remember a longer line needs to be bigger and a Manometer test
must be done figuring in low winter pressure and all adds on you may
do in your lifetime there. Dont guess, have in writing what flow you
must test at.
Another poster mentioned gas line made from corrugated stainless and
covered with yellow polyethylene - one such product is Gastite. Your
building department, and particularly your gas utility will have very
specific requirements for anything you do. You convenience doesn't
even make it into the requirements footnotes. You may not be able to
snake a line under the house and not have it supported. They may
prefer to see it buried. Pick up the phone and call the utility.
As Rico and others have mentioned, check with your local code official, most
utility companies don't care what you do beyond their meter as long as the
code official is happy. We've installed several hundreds of feet of flex gas
tubing above ceilings for school renovations (science labs) in one
jurisdiction and hard piping with welded connections were required in
another. Ask your local code official, "right or wrong" they make the
decision regardless of the code. It's not worth fighting them if they want
These guys are right about the inspector. What he wants is a big factor.
The stainless steel flex probabaly will need to be supported with something
to pass code rather than just laying on the ground. So you need to install
it before you put down the floor.
