Black tank rinse/flush on a Majestic 28a...
What I do NOT know is....where does the pipe from the toilet actually come down into the black tank?? Does anyone know? The reason I ask is because I don't want to put the tornado nozzle (which will stick into the black tank about 3-4 inches) directly underneath where all the bathroom material drops into the tank. Seems like that would be a disaster.
So...Does anyone know WHERE the pipe enters the top of the black waste tank? Does anyone know a part# or something for a replacement tank? If I saw a replacement tank (or diagram) it would likely answer the question.
Thanks in advance!

I figured it out. In case you ever wonder, on the 2015 Majestic 28a the waste pipe from the toilet enters the tank very close to the corner that is in the rear and on the inside (away from the driver side). So, it looks like I can put the Tornado tank cleaner pretty much in the middle (near the top) on the rear wall closest to the tires. That will help to blast water towards the drain which should help with flushing/cleaning the waste tank.
Regarding the Tornado device itself....I did some testing on a garden hose on my driveway (not installed). What I noticed is that there are ~5 small holes shooting straight out at a pretty tight radius/angle of about 50-60 degrees. So that would do a pretty good job shooting streams of water ACROSS the length of the tank and getting SOME spray on the walls (but not enough in my opinion, especially since the inner side wall closer to the rear is where the tank sensors are located). There are also some jets that spray out a lot of water almost exactly 90 degrees in both directions which is what causes the tornado to spin. Here is what the "Out of the Box" pattern looks like (remember, it is spinning also):
I didn't like how that seemed to be "missing" a lot of the tank walls and ESPECIALLY seeming to miss the area on my wall where the tank sensors are. So I took a chance and made a modification. I took the smallest drill bit I had and made 2 more holes (one on each side of the spinning dome of the Tornado). Even though it was the smallest drill bit I had, it still created holes that are probably 3-4 times larger than what sprays out of the top (the 5 streams that mostly go straight). I drilled on the dome in spots that made it so that the water would shoot out more on the walls. Here is what my new and improved spray pattern looks like:
I'm quite happy with how the pattern looks and I am looking forward to getting it into my black waste tank. This should make it so that I can hopefully keep my black tank clean and the sensors clean without ever having to put another hose+wand through the window and down the toilet.
I'll keep you posted and let you know how it works out.
Happy Camping!
