Which implies that the manufacturer recommends using anti-freeze. I think what bothers me most about the "blow it out" camp is that most of the proponents always add the disclaimer "done properly". And I agree it is a perfectly valid way of winterizing "done properly" but there is a large margin for error for doing improperly.
Since many of the posters here on JOF appear to be first timers, teaching them the "with a lot skill and knowledge" method is not the best way to go when there is a relatively idiot proof method that will only cost a few dollars. Once they are comfortable with their units, and they decide they don't like the smell/cost/residual taste of plumbing AF, they can decide to learn the more advanced skill method. When the crowd that blows say "make sure you drain your pump too" etc., do they think a newbie who doesn't know the first thing about their plumbing system, and possibly doesn't even know where their pump is located, is going to know how to do this?
For first timers I say, bypass and drain the WH, stick the tube in the jug, turn the two valves, hit the pump switch and run until everything turns pink from EVERY outlet. Go hibernate for the winter with no worries about "did I miss something, did I get all the water".
