underground lp gas lines?

glennster · Mar 6, 2017

so whats the latest and greatest for running lp underground? the lp line from my tank to the dryer on the grain bin is just a copper line direct buried. has been there since before i bought this farm. been thinking it may be time to update this in case the copper is getting wore out. any thoughts??

There are plastic lines. I replaced a copper line with it. Got it from a local plumbing supply. 35 cents a foot, compression fittings and push-in couplings. Fittings are pricey but easy.

Plastic with messenger wire for locating.

I just put in a new underground LP line. Plastic-covered copper line made for direct-burial was all I needed to pass inspection.

Mine has been there for going on 40 years. Copper oxide protects it.

Copper lines on the farm have been in for over 60 years with no problems,if it ain't broke don't fix it.There using plastic now because it's cheaper,doesn't mean it's better.

My original underground copper liquid line was installed in 1988. It runs around the perimeter of a bin from the tank to the burner/blower. I'm not even thinking about it. We ran yellow plastic vapor lines to a couple of buildings. I had to replace one right away. Apparently sliced it with a sharp stone. I wouldn't run that again without protection. Maybe it's not available any more?

Mine is copper from the tank into the house. We've been here for 18 years. A previous owner did the installation. An educated guess would be 35 to 40 years ago.

The LP line between my tanks and house are buried copper, installed by the gas company in 1987.

No problems so far.

I used black iron with electrical tape over the joints.

When I built my shop 7 years ago I used flared copper for the NG line, because that's what was going into the house, since then I have read that copper is not the best for NG, but it's been working in the house for 20 years.

When we bought this place 15 years ago we installed a propane tank and had to have a plumber run the lines. He used plastic with messenger wire. End fittings were installed with some sort of heat process using a torch and mold. So far so good.

When I was still working and we did road replacement projects, the gas company would come through and update all iron gas lines with plastic (cost). They would leave all copper lines alone. If it were me, the copper would stay. My copper propane line for the house was installed in 1973.

In our soils copper is close to a forever deal, that might change other places? The coop put a new 100 gallon tank at my place last year and new line, still using copper.

bob, mine is a liquid line also. is copper then whats recommended for liquid vs plastic?

jm. · Mar 6, 2017

Built this house 7 years ago. They used yellow gas plastic really cheap BUT they have to have a thing on each end called a riser. Seems it is plastic shielded in flex metal like conduit. Those two ends offset the cheap cost of the plastic line. Like ever one else all I had ever used before that was copper.

Bob Bancroft · Mar 6, 2017

Sorry- I don't know! I just know after my experience I trust copper a whole lot more than the plastic. Maybe the copper/plastic combination mentioned is the new answer. My info. is old.

The first drying bin was put on this farm in 1969. They used copper lines. That dryer has been replaced but the copper line is still good. I moved it a few years ago but the ling looked like new so I just reburied it. So it has lasted 48 year so far.

My Grand father put a propane furnace in 1955. To my knowledge the line is still the original. So If I had copper I would leave it as the plastic is not going to last as long.

As far as I know copper, schedule 80 pipe or schedule 40 pipe with welded joints are all that are rated for liquid propane. I would need to double check but I believe type M or type L copper is what you would want to use if the copper needs replaced. Also be sure to use the heavy flare nuts.

NG folks replaced all the lines in the neighborhood a few years ago they used yellow plastic pipe. I ran NG from house to shop they used yellow plastic pipe. I priced it out my cost for material $700 they initially said they would do it for my no charge but I got a bill for $700 material charge no labor. That's OK it was worth it to get off the bottle (LP)...

I have a house down the road I ran the LP with copper I ran short so stopped by the LP place looking for a short roll of copper. They told me they would finish the run no charge when they set the tank they used plastic about 15ft connected to the copper. I got a bill for something like $500 :shock: I picked the phone up and told them to come get there chit off my property. I should have just brought another roll of copper and moved on with life all this free stuff is expensive.
