Add to your steps, or change the order a bit ...
Turn off water pump.
Then turn on the hot water faucet at the sink until all pressure is off.
Then drain water heater. The anode rod won't be under pressure.
Then by-pass the water heater for winterizing.
Then blow or pump the pink.
Good luck next year!
Edit: And oh.... when all done, put the anode rod back in the water heater so the threads of the rod and the threads of the tank won't rust up over the winter months. (and they will if you don't put it back in). I always leave a note on the wall by the electric switch for the for the water heater that the water heater is drained, do not turn on the electric until water heater is refilled.)
Don't ask why I do this extra step now!
