Blowing out water lines for winter storage.
Last night I decided to blow air through my water lines to drain for winter. I started with the low point drain caps both off. I used the blow-out attachment to connect my compressor to my city wat...

Dodgeguy,
I mean no disrespect but if you leave enough water in a low piont to burst the pex tubing, you have not done a very good job of blowing out the lines. I am with the group that dislikes the pink stuff. I have used air for the past 35 years and prefer it over antifreze.
YMMV

The pink stuff works, none of us who like the air blow-out method disagree on that, but I just don't like the stuff.
A little bit of water in a pipe will usually spread along the length of the pipe a little bit as it freezes. It is valves and elbows that tend to break a little bit easier with freezing water.
I agree that if it spreads out it should be OK. I am not willing to take that risk when temps drop to -20deg! I don`t know what kind of pink stuff you guys use, but I have never had any that smells bad. and air will take the path of least resistance so it will very easily go right past the water laying in a line and anymore residual water can very easily collect in a low point (does anyone really think RV manuf`s. build trailers with the proper pitch on all the freshwater lines?) I am pretty sure they don`t. therefore I feel much better come spring that my system will be perfect.
