This appears to be a hypothetical device, but unless it has been proven in use, I suspect it is not a good idea. I don't think the thermostat valve will close quickly enough in contact with the cold dirty water to prevent contamination of the clean water tank.

A better -- albeit more complex -- solution would be to use a toilet-tank style flush/fill mechanism. When the tank reaches Pasteurization temperature, it could flush then refill with dirty water again. That way, only Pasteurized water is allowed to enter the clean water tank.

Devices such as this have been built by people who know how to test whether there is any contamination of the water by processes like you describe. As far as I know, this is a theoretical problem that doesn't occur in the real world. More info on this here and here. Thanks for your input here. Tom Sponheim 16:16, 17 March 2009 (UTC)
