Mysterious Propane "Leak"

Sorry about the length but I hope with enough details someone can explain what is a mystery to me.

After 5 years or so my propane pigtails had hardened. Since the regulator was the original from 2004, I decided I should replace it also. What motivated both was what seem to be very slow leak.

Any ideas that can explain this or point to additional testing?

Hi JimK,

It appears your camper was made in 2004, that is an older camper at this point in time. A few questions as I may be able to explain some of what you are seeing, but we need more background info to be more specific.

1. Is your camper a 2004?

2. What brand and model are these appliances,

Water heater
Furnace
Stove/range
Fridge
Outside LP gas tap off the main gas line for a grill with a quick disconnect, do you have one?

I have tested a good number of older Atwood and Dometic products that are in the age of a 2004 camper and found several common trends. While Suburban/Norcold may have the same issues, I do not have as much data from those.

3. What state in the US is the camper stored at over the winter?

4. Is your camper stored inside a heated building or outside?

5. Have you or a dealer, ever replaced any gas appliance parts other then your new regulator and pigtails? If so, what parts did they replace?

I'll type out my findings as I restore older campers, but I want to make sure they are close to what you have, and we need more specific info to give better answers to help answer where very slow leaks can occur.

Hope this helps,

John
