Water Heater Misfiring

Here's my situation. I'm fulltiming in a one year old 25 FB SE and recently my water heater started making funny burbling sounds. I also noticed black smuts on the grill where the heater exhausts so I opened it up and adjusted the flame to let more air into the mix because I thought it was burning too rich. As I was doing this I noticed a lot of condensation drained from the nozzle and also some was coming out of the tube where the flame actually burns. More air helped momentarily, but then with the cover off I saw the flame do this spit and sputter act and more water actually came right out.

As I said I full time, and normally I just leave the water heater on. The problem seems to have started a few days AFTER I had my propane tanks refilled. Is it possible for water to get into LPG? I do have a couple of small Rhino tanks that I could swap out for my bigger ones.... What do you think? Time to take it to the RV repair shop or just bad fuel?

Paula, it sounds like moisture in the fuel. Try opening one of the valves on the tank, and see if a bunch of water comes out. Most propane fueled appliances don't respond well to water injection.

Thanks

Oddly enough I haven't noticed any problem with the stove top. I've not needed the furnace since I refilled the tanks (that a/c with heatpump works, if somewhat noisily). I'm thinking that the water settled in the line to the water heater because that's a low point in the line? Think so?

Hey pilgrim... how's the leg!

Not Airstream related, but propane is propane. Last fall I installed a small gas stove in the living room to take the chill off those extra cold winter nights. Well, the first time the temperature went into the minus teens, the stove would not stay lit. The next day I called the gas supplier that provided the tank and explained my situation. They came right out and told me that moisture most likely created the problem by freezing in the small orifices in the regulator. The resolve was that they infused some methane into the tank by way of a special device that allowed them to pump in the liquid gas without releasing any propane. It has been colder many times since and I have not experienced that problem again. The methane I am told, acts the same way as dry gas does for gasoline. Any propane supplier can take care of this for you, just not the quick fill stations.

Hope this was of some value to you.

Gracias! Of course I could get home grown methane with some good tex-mex!

Anhydrous Methanol

Paula,

Tell the gas supplier that you have significant amount of water in your tanks and you want them treated with ANHYDROUS METHANOL. This will dry up any moisture in your tanks and cure your problem.

Don't forget to re-adjust the flame on the water heater .
