The city water connection, using a QC air hose adapter.

There are videos on YouTube and descriptions on here about how to use air to winterize your trailer.

I run the water pump dry. Then I drain as much water as I can (from ALL systems) using good ol' gravity. I drain and bypass the water heater. Then I hook my compressor (set at about 40 PSI, using the adapter) to the city water and go around the camper opening each faucet (don't forget the outside shower, and the toilet) and the pressurized low point drains last, until only air comes out. Since I just put some fresh water in the gray tank, I'll leave it open during this process and close it before I start dumping AF down the drains.

Then I dump non-toxic anti-freeze down each drain; enough to fill the P-traps and so that some goes out into the gray tank. And put some more A/F down the toilet to keep the knife valve in the black tank wet. I will often leave some in the toilet bowl as well (again to keep the seal wet).

It's just slightly easier than filling the lines with AF for me, and it typically doesn't get below freezing for extended periods here, so this method is good enough for our purposes. If you're in a place where it stays freezing for extended periods, you might want to put AF in your lines.

On that little screw off/on debris screen, had a friend camping alongside of us and wasn't able to get water pressure up to usable. Then noticed wet carpet near bed. Found that the debris screen cap was loose. It would pull water up, then drain out at the cap.
Just another thing to keep in mind.
