LP problem

[emu]

I hope my ingorance doesn't show through too much, but here goes. My mother recently purchased a '02 34' Classic, which she now lives in full-time, allowing here to move wherever her kids go. Last week one of her propane tanks went dry, so I came over and showed her how to switch to the secondary tank and I removed the empty for her to get a refill. Today she called and said she smelled propane. Sure enough I went over and the second tank was empty, there was a strong smell of odorized gas, and the LP Detector was beeping (it was chirping every minute or so and the light was yellow, indicating a fault in the detector?). I opened all the windows and removed the second tank. Pushing on the test button successfully reset the alarm. She hadn't used her cooktop at all, but had been using the heater and the water heater steadily. I've noticed there are two water heater switches in the bathroom. Both were on all the time. Any ideas what's going on

If you had to manually switch to the second tank, it would appear you do not have the "auto-switchover" regulator I thought all Airstreams came with.

Exactly what did you do when you manually switched tanks?

My first thought is there is something wrong at the tanks themselves, and she had the forward window open which allowed fumes to waft in.

Could you supply more details on what you did?

Just a suggestion, but if you detect an LP odor inside the unit, I would suggest that you not open windows & doors to air the odor out. One can not tell the level of gas to air (oxygen) concentration, without the proper detector, that will show the percent of gas to air (oxygen). If the LP has gone above the flash point, adding air (oxygen) into a gas filled environment can bring the concentration level back into the flash point, causing a problem. Best to leave the unit, turn the tanks to off & leave for a time.
Best,
