That's one reason for building my own connection. My compressor hose fits into the connection. I can hook it up and walk away from it.

Did mine yesterday, for a low-cost, labor-intensive temporary winterization (we go back out in 2 weeks, but getting occasional freezes now).
The air goes in at an adaptor that screws into the city water supply inlet. Air comes from a 3 cfm 3-gallon compressor, through this connector. Pressure regulator set to 60 psi.
I start out by draining the fresh water tank, hot water tank, opening the three low-point drains (you may have more or less) and all faucets (don't forget the outside shower). About 30 minutes until things stop dripping.
Then bypass the hot water heater, close all the drains and faucets, and pick a faucet to start with (I like the outside shower, it is my longest hot water run, and right beside where I am working with the air). Open one tap at a time, blow air through the line until water no longer comes out. Might be 30 seconds, might be 10 minutes, depending on bends and slopes enroute. Repeat for all taps on all drains, one at a time. Then get someone's help, to open the toilet feed valve while you blow on the line.
For my rig, it is almost a two hour job. After blowing air out all the faucets, I find that I once again have at least a cup of water collected at each of the low-point drains, so I definitely blow air through them two. Then I go to the outside shower, and blow it dry again (most likely to freeze).
Now that the supply lines are as clear as air is going to get them, I pour at least a pint of pink stuff into each of the traps, and another pint into the toilet to keep it sealed.
Alternative to blowing the lines, is displacing the water with pink stuff, pumped through each of the faucets and a little through each drain valve (because I know I have trapped water that doesn't drain, that will work its way to the drain valves as I pump air or pink stuff through the lines). This takes 1 1/2 gallons of pink stuff, leaving a half gallon for the traps (in addition to what got there from the faucets). That's a 10-15 minute job on my rig, after draining, much less time than trying to blow all the lines dry.
Everyone talks about the amount of time it takes to winterize, without mentioning the time it takes to dewinterize. There's a balance.I hate trying to get all that junk out of the lines: the taste is persistent. I'd rather take the time to blow out the lines, and when I want to leave just fill and go, without having the mess and time of pumping out the lines.
What I do...
Empty all tanks, and Water Heater. By-Pass WH. Leave plug out of HW.
Open low point drains.
Open each faucet and Toilet valve...More water drains from low points.
Close all faucets, but keep low points open.
Blow air thru city water inlet. While opening and closing each faucet and toilet valve. Just a little bit more water comes out of Low Points.
Cap Low points. About 15 minutes up to this point.
Run A/F thru on board pump to "Charge" the system full. Open each faucet, and showers, and toilet valve, till pink flows out at each faucet. Then close faucet.
Crack Low points caps until pink comes out. Then close tight. Another 10 minutes for this step. Total 1/1/2 gallons of A/F.
Water heater and FW tank stay empty. No A/F in them. Drain traps, and toilet get A/F when it runs from faucets and toilet valve adds a bit to toilet bowl.
Since there is no A/F in FW and WH tanks, no need to un-winterize.
Takes 5 minutes to button everything up and put stuff away. Half hour total.

I think some folks are saying it takes a while to flush out the pink taste from in the lines. It does take a few gallons of flushing for sure...anyone care to estimate?
Has anyone collected the pink from the lines until the water appears again? Do you get up to 1 1/2 gallons, similiar to what one might put in?
That collected amount from the taps and showerheads may be useful to put into traps the following year perhaps.
It's been an interesting thread so far. Many different choices and methods. thanks to all for their contributions.
