Polyethylene For Gas Line

tool junkie

More and more I get guys trying to sell me on the PE for gas idea and Im kind of an old school guy. Can I see some opinions for and against? Just doesnt seem durable. And what about local codes? At least in my city its not allowed for residential use. Thanks.

I admit it kind of make me scratch my head also but around here the local gas utility is pretty much using it everywhere. I suppose I would too but I'm not set up for it yet.

I haven't installed any PE gas lines for any residential projects (yet) but I have for swimming pool gas lines and let me tell you that its the way to go just need to buy more tools (110v electric heat fusion iron) also you'll need to take a short class to be certified for PE fusion.

Old School= pain cutting and treading all the Scotch-coat piping and wrapping with 10 mil tape "Boring".

Do you mean for inside or for outside?

I am strongly against it for inside. (I think it's a PEX-AL-PEX that is being marketed for inside use, not PE.)

But outside? Better than steel by a long shot.

I use it often,it's the only way to go.CSST is also legal but it has to be in a conduit,vented and grounded.I've done that as well.For the pe, if the fusion tool is not available they also make compression risers with insert fittings.The risers are coated iron and are very stable.

My stir stick........


So you WILL use it indoors at 80-110 PSI for water but not for 1/4-2 psi gas.

Apparently you DO NOT TRULY trust the integrity?????!!!!!

Experience dictates position, understanding and Rank.

Now....Care to explain the "double standard"?

If your logic is correct then let's use copper and soldered joints for gas.

See how that flies.

Only to the person who does not know how to interpret statistics correctly.

Water IS statistically, yearly, Historically, more destructive than fire. PERIOD.

Not because of a hose leak......

The standard for gas is a metal to metal joint. That makes a lot of sense to me. There are CSST brands out there that use a non-metal seal and I will not use them.

Gas is a completely different animal than water. Too many times I have seen air (a gas) leak where water would not. (Think T&S valves) So a metal to metal seal makes a lot of sense to me.

Now think about how and where gas lines stub out. Lots of times a gas line is stubbed out in places it can be easily bumped. Water heaters, furnaces, barbecues, etc. Also, many appliances connected to gas lines are movable. (Think dryer, range, etc.)

I don't know about you, but I am not interested in having those stub outs made of something that could bend and kink. Not am I interested in having appliances moved around that are connected to something that can bend and kink. There simply isn't the structural integrity there to risk all that.

I can't think of a single situation I use PEX in similarly risky situations. Except for fixture stub outs, any exposed piping would be copper on my job. That is one place copper has the advantage.

But still, a lot of it has to do with the differences between a gas and a liquid.

22rifle

Well, of course.

But that is a meaningless statistic in the narrow confines of this debate.

Here is the statistic that would matter.

On average, in any given building, will a gas explosion or fire cause more or less destruction than a water leak?

MALCO.New.York

Uh....Let me get back to you on that one......I will have to research it.....

I'd rather own one of 50 homes that developes water stains, or rotted framing than the one home that explodes while my wife and kids are asleep.
