You do want a water heater bypass, unless you live somewhere that you don't need to winterize. Otherwise you will have to fill the water heater with antifreeze, before you get any antifreeze in the hot water lines. Aside from being a big waste of antifreeze, it's a PITA to get OUT of the water heater in the spring.
