Just like the water heater, if you run antifreeze through a 5 gallon (why so big?) accumulator tank, it will take several more gallons of antifreeze and be a bear to get out in the spring. So bypass it. But then you have to drain it just like the water heater. If you don't have a valve, just break the connection on the bottom and let it drain.
