I think I have read all the posts on propane system tests but can anyone share what I can expect from a vendor? The first RV dealer said they don't do it, and the second, although I was likely speaking with a sales associate, said something like, "we hook it up and smell for gas". Having read one of the posts that said they knew someone that blew their trailer up I am hoping someone has some detail on what I should expect from a propane system test? Looks like my baby has a stove, oven, heater, one lamp, and a propane/electric refrigerator. Guessing they will make sure there are no leaks when the gas is turned on, but not go as far as to test if there are issues when the appliances are turned on? Any other tips greatly appreciated.
Here is a picture of the hookups just for reference, copper looks very solid, guessing the regulator is older but may still be fine, and the tank connects may need adapters as I plan to get new tanks. propane by Tom Myers, on Flickr
New tanks is a great idea... You can test it yourself if you want to try. Hook up the new tanks (original fitting will screw "backwards" into the tank). Check to be sure all gas appliances are off; don't forget the gas light. Slowly turn on both tanks. This is to prevent the OPD valve from stopping flow from a rapid surge of pressure. Check inside and outside. If you smell gas, STOP.
If no gas smell, use gas leak detection solution (better than soapy water) and check every fitting. Give it a little time and look closely for bubbles at each fitting. If it all looks good and you still smell no gas, test for another hour. Close all windows and the door, leave the tanks on. Take a good sniff after the hour passes. If it still seems OK, test several times in the next hours. I leave mine on over night. The next morning will tell the tale...
A reputable professional RV shop can also test the system with the use of a manometer. That involves using the stove manifold to test the pressure for a certain time. If the pressure holds, no leaks. I have my own manometer and use after performing the leak solution/sniff test.
