Re: water line winertizing
The ideal way to winterize is to use both compressed air and the pink stuff. Using air is easy, you pick up a "Blow Out Plug" at any RV dealer (they are cheap) and screw it into the fresh water hose connection... keep the pressure low or you could blow out more than water.
However, even after you do that, there are always low spots that left over water collects in, and subsequently freezes and possibly expand enough to burst your pipe. There are other things to consider too, even a few drops of water in the wrong place like a faucett or pump impellers will also cause problems once it freezes.
Using the pink stuff (and that stuff is cheap too) eliminates any and all problems, you flush the lines and it is all replaced by this stuff, all the nooks & crannies.
The more experienced RV'ers like to use the pink stuff first, then drain it, then blow it out as they don't want to leave the stuff in the lines all winter. Myself I just used the pink stuff and leave it in there.
