Just to add a bit. The Sewer Solution is for emptying the tank into your home toilet or some other type of smaller sewer pipe. it is not meant for backflushing the tank.
And with the Tornado, if you run the rinser the entire time (filling and draining) I think you will see the tank will get cleaner. because the action of the rinser will aid in pushing the "stuff" toward the drain as well as the suction of the drain itself. maybe give that a try and see how it works. otherwise, it is a great an enlightening video!
BTW I have a regular tank rinser, (no spinning action) and as far as I know it is working great.
Also maybe use the elbow with the hose connection on a "straight" tank connection to see how far and well it gets into the tank.
Thanks for your time with the experiment. very interesting what goes on inside there! :E
