Why not spend a bit on a couple gallons of RV antifreeze and be 100% sure your are ok or blow out the line and HOPE you got all the water out?
Either way takes about the same amount of time by the time you get the compressor out and hooked up. Also, I have never had any residual taste remain after running water through my lines in the spring.
Did it both ways during over 40 years of RVing. Found out the hard way that the black tank flush line does not get winterized by using the antifreeze. Now, I blow the lines out and then put the antifreeze in. Takes just a bit longer but I know for certain that my RV is safe during the cold Michigan winters. :)
