Don't rely on blowing out your lines. Some water will remain and collect in low points which will freeze and break pipes. The only sure way is to use antifreeze method.

Maybe I'm lucky but I only blow out the  water system to winterize.   Since we 'camp' year  round I have winterize two sometimes three times a year.   I follow the factory instructions to the letter.  I did learn to turn off the water pump then run the hot water side till there is no pressure in the line.   Then I remove the hot water drain plug slowly just in case.  

 

I winterized with compressed air after first emptying the hot water heater.  I decided to take the plug out of the water heater a second time after I was done just to make sure it was empty.  Compressed air had filled the tank and I got a sudden blast of air and water - roughly a quart or more or water as I loosened the plug.  It was enough to soak one of my pant legs.  There is no apparent damage but what went wrong?    Frank

Just goes to show common knowledge can be wrong and maybe blowing out lines does work. At this point though I think I'll stick to the antfreeze method just because I'll sleep better on really cold nights knowning my pipes are full of atifreeze instead of wondering if I blew them out right.
