Exposed gas piping on bottom of 76 Sovereign

Renovating a 76 Sovereign as a newbie, and the lp gas piping is fastened to the underside of the bedpan. I'm assuming this is aftermarket work. Concerns me since it exposed to rocks or road debris while traveling. Wasn't this originally installed elsewhere, more protected?

Are you sure it's connected to a bed pan? It should be attached to the belly pan, on the underside of the trailer.

No. It's supposed to be that way. The intent is, if a leak does develop, it dissipates harmlessly instead of building up in an enclosed area.

It's a 1976 trailer, and the propane plumbing is still there and still intact 41 years later. That by itself should tell you that it's safe, and not in any particular danger from flying rocks and road debris.

Belly pan is what I meant. It is on the underside of the trailer. So that's how it should be?

I believe rv codes call for lines under, and exposed, as to danger of leaks in enclosed area, and as others have stated, AS installed this way.

Ok, great to know and makes sense from leak/safety standpoint. The previous owner has done some other work that is suspect (loose water plumbing run underneath hallway goucho, open ended piping going to nowhere, etc.) , so I questioned this. I've ordered a service manual for this model year, so hopefully that is going to help.

Typical

I thought the same when looking under my first AS. Seemed unwise to expose the piping to potential damage but I learned the reasoning behind it and it makes sense. One thing you can do to reduce the chances of damage is to split some pex and use it to cover the copper..

I have exposed propane lines on my 2013.
I assume they're all this way.
Possibly to make it easier to detect leaks and replace lines?

Hi Scotty,

Yes as others have said, totally normal for the LP piping to be under the AS.

Here is the manual for your trailer I think:

https://www.airstream.com/wp-content...0110i.arc_.pdf

For other old documents at the main Airstream site:

https://www.airstream.com/

. . . just click on the Service tab at the top right, and then hit Manuals or Document Archives in the drop-down menu. There is a fairly good selection plus some videos. YouTube also has many how-to videos FYI.

Also, you might be interested in this sub-forum which covers your '76 Sovereign model: [edit -- see that you already know about this forum!]

http://www.airforums.com/forums/f221/

Good luck with the new Airstream!

Cheers,

Peter

Risk of explosion

A Propane leak in an enclosed space is an explosion risk. Also propane is not good to breathe. The opd valves in propane tanks prevents overfill so that a tank stored at home won't fill the garage with propane and cause an explosion.

It' def. will blow when garage filled with gas, as I witnessed when former national hot air balloon champion owner pilot turned cyl. on in garage w/furnace at floor level, result massive explosion and fire to house. Also propane will kill you if breathing it.

Any chance we could keep this thread from turning into a free-for-all "dangers of propane" thread?

The OP had a specific question which appears to have been answered IMO.

Thanks

Not a chance, people want to impress others with their knowledge, whether accurate or not.
