If you use (air compressor) air to winterize your rig, then you really don't need the bypass system. Simply remove the water heater drain plug, turn the compressor on (or turn on the valve), jump out of the way, and let the air blow all the water out. I do this first, put the plug back in...and last...then pour a cup of pink anti-freeze into each sink trap. Whatever is left over, I divide (as equally as possible) between the both/shower (grey water tank) and the toilet (black water tank). Has always worked for me with no problems in the spring.
