On one thing I do agree that I don't think a reverce enama would cgeat a flow. in my line I said about using a toob going from the mouth to the rectom the other person said a large enama to do this. I do't think one could ever get a enama to do this, do the the valves in the digestive system to provent this.but a toob going though works with the valves and just keeps them open but blocked so only what is in the toob flows.
