Waterline Blowout using Air Compressor Low-Pressure

[jjwink]

We live in the Nashville area and use the blowout method on our Landmark. After we are sure all water is out we do put anti freeze in the ptraps. We leave for AZ in early Jan and have never had a problem. We don't "usually" have extreme cold until mid Jan-Feb.

I use a compressor hooked up to the adapter and blow out all the lines. I also put some air through the traps so that when I add antifreeze it is not diluted.
I then run antifreeze through all the lines.
I then leave everything open.
