Interesting report. Looking at your own "stuff" coming out of your clear elbow is kinda fun and sorta mesmerizing. Looking at someone else's stuff (even if only pics) is kinda like the smell of someone else's f*rt. Not pleasant... :B
Did you notice any improvement in false tank readings? It would be interesting to run a camera inside to see how clean it really is. How clean does the bottom of the tank seem if looking down the toilet?
I am of the opinion that getting the tank as clean as possible inside is a good thing. We always fill the tank to as full as possible holding the toilet pedal down. That's the slow part I don't like. Then I let it rip. If towards the end, there's still some solids coming out, we fill the tank again and repeat. We're normally at FHU CGs and I let the in-tank rinser run for 15-20 minutes while breaking camp. No additional time required. Looking down the toilet, the bottom of the tank is spotless (except for some droplets of ABS glue from the factory). But I have no idea how clean the rest of the tank gets. The sprayer is on the same wall as the sensors - dumb design.
Any time we need to use our tote tank, it gets filled once and if there's some solids still coming out, that's too bad and will have to wait for another trip to the dump station. What bugs me is when I can't hook up the in-tank rinser at a dump station (providing there's no lineup). In the beginning, it didn't take long to discover how important it is to add a few gal. of water before each use of the tank and not to skimp on water when flushing
"Back flush" elbows aren't going to be very effective due to bends in 3" outlet pipe. Some tank configurations also reduce the effectiveness of the spray. You can't beat an down-the-toilet wand except for the hassle of hooking it up to a hose.
