dont use auto antifreeze if your on a septic tank.

If pipes can freeze I would blow down lines using compressed air and
add a security system to call for help if it gets too cold, or someone
breaks in.

plaster washing machines, dishwashers etc are also at risk.

freeze thaw cracks plaster bad

On county sewer.

No washing machine, but the DW bothers me.

I will assume that plaster=plastic.
