As I said in a earlier post, when I winterize I simply "Gravity Drain" the fresh water system.....(I use NO RV anti-freeze and NO compressed air).
If/when the"gravity drain" method is used to winterize, everything must be drained
If everything is not drained properly
freezing damage can/will occur....
(especially at risk are the water pump, the toilet flush valve and the ice maker solenoid valve).
BTW, if the "blow out with compressed air method" is used, any/all water must
be blown out, (or freeze damage can/will occur).....
If the "RV antifreeze method" is used, everything must
get antifreeze into it, (or freezing damage can/will occur).
