For sure I am probably doing more than needed by both blowing out the water lines then also running antifreeze in them.

I have found though that even after blowing out the lines that sometimes when running the anti-freeze, I get clear water for a second or two before the stream turns pink. So I am not all sure whether or not blowing the lines gets rid of all of the water.

I suppose though that by blowing out the water, there is less of a chance of diluting the anti-freeze initially.

And actually - come to think of it - the reason I blow out the lines is for "pre-winterization". For example, if it looks like the temps will dip below freezing - and if it is before we winterize the coach for good, I usually blow out the water lines.

Then if we go camping again, it just takes a couple of minutes to run all of the air out of the lines. And I am not wasting anti-freeze during this period if we get warm weather later, and go camping once or twice in the late season.
