I leave the hot water tank open after I drain it (REPLACE DRAIN PLUG OF COURSE TO ALLOW PRESSURE TO BUILD UP). This way I ensure all the water is blown out of the hot water pipes - essentially replacing all the water in the entire system with air instead of water.

Place antifreeze in the traps and ensure the antifreeze gets to the black and grey drain valves.(open both and allow a little to drain in a bucket to ensure the entire length is protected and drained of water.) I used RV antifreeze in the drains but you can also use windshield wash antifreeze in the drains.
