Flush King use with Well water source.....yes or no?

I would not attach a drinking water source to the Flush King (I have one but only use it with the non-potable water at a dump station). Any fecal bacteria that would make its way into the drinking water could have serious impact on others drinking the water.

A backflow preventer would help - a lot - just be real careful not to give any other innocent people any GI distress!
