After great effort, I just now found my very slow propane leak (and I will soon prepare a fascinating ;) report on the many things I learned while trying to find it). Bottom line – the leak is at the point that the external barbecue fixture connects to the propane system.
What I want to do is remove the barbecue fixture – we never use it. And I want to cap off the stub or nipple that "tees into" the propane line. The pipe is galvanized. It appears to have an ordinary pipe thread -- not a flared brass gas fitting.
I am planning to unscrew the existing reducing bushing (I think that is what it is called) and replace it with a galvanized cap. I will use teflon gas tape at that joint.
My real question is this: I don't want to put any stress on the other galvanized propane lines underneath the trailer. I will hold back on the galvanized nipple with a pipe wrench while unscrewing the existing reducing bushing. The bushing is very rusty -- I anticipate having to use a lot of force to unscrew it. I'm planning to spray it with WD-40 a day or so before unscrewing it, to try to loosen the threads.
Does this sound like the right approach? I am not a plumbing or propane expert, as you can tell.
Thanks in advance for your suggestions!!
I'm curious regarding the source of your leak ... was that an "Extend-A-Stay" adapter fitting that developed a leak?
If so, I was thinking about installing one in motorhome's propane system for use of a 5 gallon propane tank to supplement the main tank on long campouts - plus maybe also power our outdoor BBQ ... but have held off because I didn't want to introduce another potential leak source into my propane system.
Here's a link with a photo as to what an Extend-A-Stay adapter is for a built-in propane tank, which may be similar to what you have on your TT for use with an externall BBQ:
