How to clear all the AF from the systems

Gulliver

We have a 2015 T@B and winterized last fall.  Is there an efficient way to clear all that AF from the lines and tanks?

One way is to fill the fresh water tank, and simply use the pump to draw fresh water through the lines until they are clear.  When I sanitize my 2017, I sit there at the kitchen sink and take small container, fill it up, pour the container into a larger bucket, and keep going til I get about 10 gallons out. Tedious, but it works.

Another way is to simply run the pump and allow the solution to drain into the gray tank, and then empty the gray tank into a bucket, etc, and then simply pour it down your drain at home.  Or, at a campsite with hookups, drain the gray tank into a RV dump.

Or: drain the fresh water tank.  With the valves in the "Winterizing" mode, use "something" to either run fresh water through the city water connection to each faucet.  With the proper fittings, and with some sort of pump, this could work pretty quickly.  Or, even use a small compressor to drive the AF through to the faucets.

Recently, through some miracle of the web, I found a "Winterizing" thread from waaaay back in 2015 from "Pop-Tab".  They developed a very simple garden sprayer pump to drive AF into the plumbing lines "without" having to fill the fresh water tank with AF and then use the pump to bring the AF to the faucets.  

This thread has the instructions on how to build this simple setup.  I'm certain that this process will work through the city water connection even with the simplest of manual or electric pumps.

I built the same version of "Pop-Tab's" pump, but, of course, would up on YouTube and found people who have modified these spray pump bottles to do many things, such as basic fluid transfers.  One video showed me how to completely reconfigure my pump bottle with 1/4 inch inner diameter tubing and 1/4 inch valves, etc.  The "original" version of Pop Tab's pump worked fine, but the "reconfigured" version turned out to be more efficient and powerful. This is the video that shows how to do this.  (PS:  I made my version with the HDX 1 gallon sprayer from "local big box store" and the ergonomics and finishes are just terrible.  How can you make a pump sprayer with the pump handle with such sharp edges that it will cut your palm?)  I'm going to find a Chapin 1 gallon sprayer and use that one intead.
