holding tanks and freezing

[Gardner Yeaw]

I suppose I could look into electric tank heaters, but it seems to
use a bunch of electricity. I would guess that you would attach them
to the bottom of the tanks and then put some kind of insulation over
them to keep the heat in. I think I am beginning to understand where
the term 'hot sh&%$t' came from.

open the dump valves and let water slowly run from faucets servicing
the gray and black tanks. In my coach it is the bath sink and the
kitchen sink. When the temp gets above 30 we shut them off. No
water, no ice. Moving water is difficult to freeze. This may not
work in extended sub-freezing situations and very low temps but the
Snowbirds in SOB's do this. Snowbird engineering in NW FL I guess.
Water is in the park fee. LOL
