22 degrees Question

[Newell Attack]

Hi Gang,

Well here in Ocala it's going to 22 tonight. I got propane so will
run the furnace.

I've unhooked the hose.

My only question is should I drain the gray tank?

I've lived in here in 9 degrees, but was draining the gray tank so it
was empty.

If you have a working 120v heater in the wet bay, draining the tank isn't necessary. If you don't have any working heat source to the wet bay, you might try putting one or two 60 watt light bulbs in the wet bay plugged in to add heat. Make sure the compartment is as air tight as possible.

If it isn't too much trouble draining the tank isn't a bad idea but the other piping in the wet bay needs the heat as much or more than the gray water tank does.
