Did it twice
Well a few weeks ago I used the internal pump to suck antifreeze into the pex lines. This is my first winter prep, it was simple enough, but i also purchased one of the air hose adapters when I first got the TT, and you can use this with your City Water inlet to blow out the water lines.
So being the nut that I am and knowing that nothing in the lines would be another option to antifreeze, and having two other projects I needed to address before putting Applejack to sleep for the winter, I decided to bring her home one last time.
I blew out the lines and the water tank, I might have gotten some of the antifreeze in there when I did it though so I will likely have to flush it out good in the Spring. But overall, it was easier than sucking the anti-freeze into the lines, as I had a little more control. I trew antifreeze down the drains and into the toilet. I also made certain to run the outside kitchen sink, outside shower and the low point drains. The fresh water drain was empty, but i thuoght I would get air shooting out if I had the compressor hooked up, but instead, I got nothing.
How can I blow out the fresh water drain? Its empty, but I wasn't exactly sure how to get at it.
