My compressor is too small to blow out effectively, so I use pink stuff. Our rig is quite simple, and the whole process takes 15 minutes or less.
First I drain the tanks, including fresh of course, and bypass and drain the water heater.
My rig has three input fittings - tank, city and black flush. I have a small electric pump that I connect to each input and pump antifreeze for a few seconds to ensure those lines are filled with pink. Fresh tank drain is open, so any that makes it into the tank goes right back out.
Then I disconnect the suction line from the pump and attach a 3' hose. That goes into the jug of pink stuff. Turn on the pump, and run each fixture and the the toilet until it comes out fully pink. This also ensures the traps are all filled with antifreeze, as well.
Reconnect the pump line and I'm done. Easy peasy.
In the spring, I just connect my garden hose to the city line and run the heck out of everything to clear the lines. Takes 15 minutes or so. We might get a bit of foam when first turning on a faucet during our first trip, but that clears quickly.
This works well for me. Easy and quick.
