holding tanks and freezing

[Leroy Eckert]

Gardner:
We can get into the high teens and the low twenties in NW FL. We 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
