Doctor Poop,
Again excellent testing and reporting. Thank you for your time and efforts. I agree that the Sewer Solution is more for when you get home and need to dump your tanks into what you have at home and not really a tank flusher.
It was interesting to observe that flushing into a 3" drain line allows a greater flushing action, but "dead zones" in the corners continued to be a problem. Slopping the bottom of the tank might improve the situation, but that is more a manufacturers design issue.
The Tornado was really the only real functional flushing tool and definitely gave better results.
My only comments/suggestions are regarding the Tornado:
1. Instead of flushing and then using the Tornado, what would happen if you ran the Tornado simultaneously during the first flush? Possibly save the second separate filling.
2. I noticed that the Tornado was mounted level. Would there be any benefit if the wedge was used and the Tornado was angled down, towards the main drain?
3. From what I was able to see, the Tornado spray head rotated with water coming straight out the head and at 90 degrees. What would happen if the head was slightly modified with one or two additional holes at 45 degrees? It would reduce the force slightly but would give a better spray pattern.
Again Jim, WELL DONE!
