I built a clear black tank and tested the Sewer Solution

Fantastic!

Don't stop there. Put a lid on it with a vent line. Add a back flush device and you could make a 1-hour documentary.

Of course, we would all think you are really sick as opposed to just plain wrong. ;)

I do wonder what difference working against a small vent line would have on both systems. My guess is that the time of the 3-inch gravity dump would increase, and the sewer solution would stay about the same.

Thanks for using simulated waste. I was taking my lunch and checking in with the RVnet!
