Draining Plumbing for the Winter

Is there a particular process to drain the water tank and lines? I will be taking the boat out in the next few weeks and want to make sure I do the right things for my first wintering process. Thanks!

Last year I sponged out the fresh water tank and put in a few gallons of RV antifreeze, pumped till I seen it come out both faucets. Filled the head sink with RV antifreeze and pumped it into the head and then poured a gallon in the holding tank. Everything seemed to have survived the winter.

I think it probably works better if you sail it down to the Bahamas and baby sit it down there all winter ;)

Only problem with the RV antifreeze is that you might tend to taste it in the water for many months. When I had to winterize my boats I preferred to blow it out with air pressure after draining the tank(s). Putting a "T" in the water line makes this a lot easier.

A friend of mine used to use cheap vodka.
