I use two of the bigger RV tanks and at this time of the year when usage is highest I can get two weeks out of each one. I just switched over to the second tank last weekend but I got up Thursday and when I tried to light the stove to make breakfast nothing happened. The space heater was going so I hadn't noticed that the furnace had turned off too but I fiddled with the thermostat to make it come on and got cold air, then I switched the fridge from electric to gas and got the flashing no gas available light.
So, thinking it's odd that I've gone through a tank that fast, and wondering if it's leaky, I go out with a flashlight to switch tanks and find that the tank IS about half full, just like I expected. Well, maybe something is wrong with it.
I hooked up the little BBQ size tank I keep on hand as a back up but the little tank didn't do anything either, everything is hooked up correctly, and I'm was running late so I had to leave it.
After asking around I know I either have something wrong with the regulator or a clog in the line. If I'm lucky it's just that the screen on the regulator is clogged because anything else will require a repair man. I wasn't able to check it because I get home after dark and I got up this morning to 40F temps and a steady rain so I'm not sure when I'll go out to deal with it.
It was 50 in my living room this morning since I don't trust the cats enough to leave the space heater on overnight. I'm going to have to cook breakfast on a little sterno stove. At least I have a warm comforter and a heating pad.
This is when you really need a man around the house to send out into the freezing rain with a strong cup of coffee to deal with stuff like this.
ETA: I haz gas! *snerk*
All I did was blow in the regulator reconnect everything and voila!
