I drain and blow out my system and bypass WH... Then I still suck in RV antifreeze to make sure the water pump is protected and I run antifreeze out all the taps , toilet, etc

I also pour a cup down the sink and shower drains for the P traps.. and I pour sme in toilet bowl to keep seal lubricated.

I run the pump after blowing out. Of course I am in central Texas and well Winter here is a joke to most of you folks up North
