Here is what I do. I've been known to winterize 7 times in a year.
1. drain the water heater
2. blow out the lines with compressed air, one faucet at a time.
3. by pass the water heater
4. install antifreeze
5. blow out the antifreeze catching as much as I can.
This is known as the belt and suspenders approach. Either 1 through 3, OR, 3 through 5 should be enough. Doing both is unnecessary, but hurts nothing. However, keep in mind that where pianotuna lives, it gets colder than, say, Florida.
But water doesn't freeze til 0 deg up there...
