I appreciated the video as well. Thanks for your time and effort.
I also use one of the flexible, through the toilet, wands. Since I can push the flexible part into the tank about three feet I wonder if this system is doing just a bit better than the tornado which only works well at the far end of the tank? The head on the wand spins similar to the tornado so it spins farther down the tank. Hmmmmm.....
My RVing friends think I'm a bit anal about the black tank and they're probably right. I got a kick out of the video, thanks again!
