What is the best way to winterize the fresh water system, hot and cold on a 420 hunter, and please don't say have the yard do it
Actually it does not and as far as the "lazy" way to do it, this will cause much more work later on when you have to replace a cracked tank. If that is how you typically winterize, you are very lucky. The pump will only drain whatever it is fed from, not into (the hot water tank).running the faucets dry on the hot side empties the water heater. turning the pump back on fills it with anitfreeze from the water tank.
Second this. you need to get the water out of the HW tank. I drain the tank and still add a little pink stuff to the tank as I am not sure the drain valve gets all the water out.Actually it does not and as far as the "lazy" way to do it, this will cause much more work later on when you have to replace a cracked tank.

Dumping antifreeze into a tank to pump through a full hot water heater serves only to dilute the antifreeze which is not supposed to be diluted as doing so makes it TOTALLY ineffective.
It takes less than 5 minutes to drain the tank in which case you don't need to put anything else in it nor do you have to flush it out in the Spring.
