The faucets that did pass antifreeze I assume that this was both hot & cold, and they were turned on separately. I also assume that you engaged the hot water heater by-pass valves (at HWH) and the fresh tank by-pass valve (at pump) as well.
If above is true, then I'm stumped.

On edit: When you open the kitchen/bath faucets, does the pump even start....., any air coming through the faucet??
