Today I worked for an hour or so adding a swing check valve upstream of the three way valve. The top of my storage tank has a nice spattering of solder. It relies on gravity to stay closed when water is not flowing in from the cold supply. Like the double wall on the heat exchanger, this is another system component that ensures that water will never work backward into the city water supply. The unsoldered 90 between the labelled ball valve and check valve will actually be a couple 45's which will clear a the upper vent pipe in the background without resorting to 180 degrees of bends. The less pressure drop around this system, the better!
