Still can dump into the WH if it's been emptied.

If it bypasses the cold water fill side, then meets the T of the hot/exit side, and there is a one way between it and the tank, it will not fill.

Yes, but I'm not aware of a check valve in that outlet line. And if it is there that inhibits draining of the HW pipes and HW heater from the hot low point drain. All said I think the three valve setup, or two either/or valves, is best. Actually two either/or valves might be better since you would get either hot water, cold water, or no water, but not luke warm water. |

At first I thought it must allow some antifreeze in, but it can't be much. I used slightly less than a gallon in the pod, and slightly over a gallon in the Salem, which I expect since the plumbing system is a little bigger. Last year I even tried to drain the WH again when I was done and didn't get anything out.
