I prefer the pink stuff method. Once you do it a couple times it should take you about 30 minutes. All you do is drain all the tanks completely, Set you water pump to winterize and draw fluid from the gallon jugs through the lines. Make sure to get some in each drain trap. Your water heater should have a winter setting on the valves. You should get by with 2 or three jugs which you can buy for about 3 bucks a piece. Remember you are not filling any tanks with pink stuff just the lines and traps. Really easy and a lot easier than a broken pipe. The pink stuff is non toxic. Blowing out the lines works also I have done both but feel more secure with running the pink stuff through the lines. All though I haven't broke a pipe yet in twenty years with either technique.
