Thanks everyone for the great help!! I was unaware of the check valve that doesn't allow hot water to flow into hot water tank from the hot side....
What i plan to do is put a valve on the intake of the water pump and then blow out the lines with an air tank. Then pump the RV Antifreeze into all of the lines until they run pink. Then, drain the Hot water heater last.....Sound good??
Drain and flush WH tank prior to bypassing....I turn water supply back on after removing drain plug to blast crud out drain hole.
With WH bypassed pump the anti-freeze thru system (Hot and cold sides) then check if any got into water heater. if so check valve leaked
