Like wa8yxm states there are 2 ways. blow lines or fill with antifreeze.
I fill my lines with antifreeze. I live where it gets below zero a LOT and for long periods of time which WILL freeze and break a line if you just blow out the lines and don't get every drop out of the lines. I don't like to take any chances.
I put the anti freeze directly in my fresh tank and pump it thru the whole system via the water pump. Been doing it for as long as I lived in Wisconsin. It's no different than pumping the anti freeze into the lines. The way I do it I 'know' I have antifreeze in the water pump.
De-winterizing fill tank with water open drain valve and drain the residue that might be on the bottom. Fill with fresh and drain again.
No problem. BTW it takes 10 times longer to get the smell and taste of chlorine out of the lines than it does antifreeze. :W

It is interesting that it seems that for every person who makes this statement, there are often 5 or 10 people who say "I just blow the lines out, been doing it for years, never had a problem!"
As for me, I set the pressure at 60 PSI, blow out the lines, drain the water heater, disconnect the pump and run it dry, empty the pump strainer, drain all tanks, put pink stuff in the drain traps, and I'm done.
Just like every fall a guy comes by with a big high volume trailer mounted air compressor, and blows out my underground sprinklers. I have never had a problem there, either.
Blowing out the lines DOES work!
