    Using a back flush unit, is it possible to back flush so much water that the
    black tank water over flows out the toilet?

    I guess I could watch the guages (if they're correct) and or have someone
    peek down the toilet while I'm doing this. A better way?

    PS: I'm new at this. The other froums have my name all over them.
    Thanks a million to everyone for being patience and informative.

    Yes, you can overfill and yes the water is going somewhere. When I do it, I watch my gauges and dont let anyone interrupt me. :laugh: :laugh:
