If your cleared lines are all straight, with no curves, the pipes will not fracture from ice pressure. Water pooling in the bottom of a curved pipe will freeze first at both ends, increasing the outward pressure on the pipe as it freezes towards the middle. (Resulting in a crack -- and a leak).

I take a couple of extra minutes for steps not mentioned here previously.

1) In the toilet's water tank, I drape a rag under the float ball which "wicks-away" all the antifreeze/water solution downward into the bowl.

2) Over the RV antifreeze in the bowl, floats a thin sheet of plastic to guard against evaporation. (I haven't missed a summer season for 12 years, but you never know).

3) At the "fully-drained" hot water tank, I attach a short length of garden hose, and reverse-fill the bottom of the tank with RV antifreeze. (You can hear it gurgling into the pool of water that remains after draining).

So far, so good.

Yankee note: My previous local "winterizing guy" preferred "used" automobile antifreeze.
