Is CSST really such a bad idea?

[Tabasco]

We are at the point where it is time for gas. All of the original copper and related is gone. We are not running a propane fridge, no heater. Just water heater and the stove. I really do not want to run copper under the trailer. If I run the flexible I can do it all with just two fittings for the interior and completely concealed. Anyone else not blow up from doing this?

I've got CSST on mine and haven't had any issues. I'm keeping an eye on it due to all the reports, but all connections have been leak free for a number of years. Rubber tubing is wrapped around the CSST at entry points so that probably helps with vibrations.

Did you ground yours when you did it? I also hear where lightning is a concern. I can certainly see where grounding it would be a decent idea but the original copper was not. I personally think I am going with the CSST and let the others sweat it.

I'd get Lewster's comments ...
Pretty sure the gas pipes are under the trailer for a reason.

The copper gas line on my 77 Argosy was grounded by a #10 wire clamped to it and the frame in the front by the LP tanks. I am sure it came that way from the factory.

Certainly possible that the grounds were removed. This thing was jacked with plenty before we got our hands on it.
I certainly have seen some valid reasons for the copper being under the trailer and understand. I just keep thinking that the advancements shouldn't be ignored. I am really on the fence here.
Lewster's?

Gas flex is not rated for use in mobile installations. In addition, all connections other than to the appliance being supplied must be accessible from outside the living space of the RV.

It's been a while since I had to reference those regs., but they stand out in my memory.

Thanks Lewster!

Oh... Lewster is a person.
Hi there, I appreciate you chiming in. Is there some sort of a link to get me to where I should be looking at this?

IIRC, It's in the NFPA Standards #58

You might want to visit CSST Safety. They lay out a pretty thorough set of details. If you get the black CSST that is tested and listed to ICC-ES LC 1024 and keep it outside of the living area you are probably in a good safety zone. Running any kind of gas line inside a living area is a pretty universally bad idea.

Hello,


I would just stick with copper. It is cheaper, easier, and is proven with YEARS of safe service.


I am not picking, just curious to see if you have found a solution I have not heard about.

What do you intend to use for heat?


Regards,

JD

The reason that the copper is run underneath is simply that it is safer. With the lines run underneath, a leak would not be as dangerous because LP gas, being heavier that air, would sink and dissipate when released. If it were run inside, a leak would be contained and could not dissipate. Enough built up gas, and an ignition source would then cause a very bad day. As for CSST, as mentioned above, is not listed for this type of use. Grounding it in a building is dependent on the manufacturers instructions and the local building departments interpretations. If hit by lightning, it has been known to develop pinholes. Major leak hazard. I personally don't like the stuff, and would not use it. But thats just me.

Yes, the manifold is bonded. Easy to do.
