For you guys operationg LR45's, when do you begin to worry about the water in the lav sink or toilet freezing? Meaning outside temps at night, and once this becomes a concern do you guys drain both systems after each flight when staying over night in that temp or lower?
I have heard the Russian's dump cheap Vodka down the toilet to prevent freezing.
