The bypass valve to the Truma water heater needs to be turned to winterize the trailer, but the handle of the bypass valve is gone. I remember noticing that the handle was, for some reason, not attached to the bypass valve, and it has apparently popped off and is somewhere in the bottom of the trailer, and I've been unable to find it.
One of my questions is that it looks like I could get a wrench on the hard plastic nubbin and move it but I don't know how to tell if I've turned the valve to the right place? Is there a way to tell that?
So, I'm in Mammoth Lakes and a major winter storm is approaching. I have a couple of options:
Moving the bypass valve
Sticking it out here through ten inches of snow and cold temperatures over two days and then it will warm up fairly quickly, although nights will be very cold for awhile. (I'm in a rental car right now (that's another story) - an AWD RAV4 with low clearance and no snow tires.
Leaving the propane on and skedaddling to lower elevations. It seems rather dangerous to leave the propane on, though, when I'm not there.
Trying to get a very expensive tow to a lower elevation over an hour away
Suggestions?
