Blowing out water lines mistake ??

Considering the low cost for anti-freeze (about $3.47 per gal. at Walmart). I can not understand why anyone would just blow out the lines and pray they got it all out. Just a little amount of water left in the system could result in some big expenses for repairs and parts. Not worth the gamble to me.
I blow out the system, drain every tank plus the water heater (leaving the plug out) with the by-pass set, then I pump the system full of antifreeze, add some to the traps and some into all the tanks.
When spring arrives I flush out the system, run a bleach water solution through the pipes, rinse again to clear our the bleach smell and taste. No leaks, no blown out pipes, no cracked tanks....no big repair problems.....Happy, Happy, Happy!!!

I used to own a Starcraft hybrid and it was a breeze to winterize. Under the decent sized bathroom cabinet the water pump came with the auxilary hose attachment to suck the pink stuff through the lines.

I "upgraded" to an Airstream and the water pump is located in a very tight compartment that Houdini himself would be challenged to work on.
The Airstream dealer told me that they use only air and told me how to go through the system. No problems for me but, as a few have already mentioned, you have to do it right. Hey, you have to do it right if you use the pink stuff too so beware. Things can go wrong. I managed to break two, not just one, kitchen sprayers. One when I was using the pink and the second a few years later when using just air. I doubt I will break a third one. I am a slow learner obviously but I am learning none the less.
