That's actually kind of a cool idea, and not really all that expensive.

I've always blown out my lines, and never had any issues. But, I have an air compressor that I can do that with. Not everyone does, and if I ever needed to blow mine out away from home, I couldn't do it. With this, you could.

I have avoided putting anti-freeze in our lines, because I don't want the stuff in the lines, because it makes the lines and the water taste, so I blow out...
