The water contained by our house is working all except for the hot wet.
We use propane and we did run out the night past last, but get a miniscule amount of propane put in our reservoir.
and cannot get anymore until tomorrow or the subsequent day because where on earth we get propane from completely run out of propane. which is stupid cause we're right within the middle of a snow storm for the last 3 days.
anyway, why wouldnt the hot marine be working if there is at smallest a little bit of propane?
is in that not enough for hot hose down?
cause if the knob is turned to the gone (the hot side) nothing even comes out.
whats going on?
What type of wall electrical outlet is this?

Not enough propane vanished to run the hot water cistern.
