Every time we disconnect a propane tank to refill, clean or whatever, we have to go through the routine of refilling, or charging, the entire propane line of the trailer. My wife gets frustrated with trying to get the pilot light on the oven to work. Think thermal coupler. She has finally accepted that the easiest way is to get all 3 burners going on the stove top. When there are solid rings of fire, with no fluttering of air escaping from the propane line, we know the propane line is recharged and things with thermal couplers will light easier.
