Well....I actually have done all the right things, or at least tried to, in terms of leaving a few gallons in the tank, flushing the toilet with lots of water, not draining 'till at least 2/3's full and not leaving the valve open when hooked up at a site. Of course, what I learned yesterday makes me think I will not drain 'til the indicator reads full from now on.
I guess what screwed me up was that the first couple of trips where short and I did not want to leave it sitting without draining since we where coming into winter at that time as I was concerned about freezing.
I do have the dreaded "pyramid" - that's what started this whole ordeal.
And the flush system is a permanently installed part that came with the unit. Nothing more than a hose connection on the outside that runs to a nozzle mounted inside the black tank.
Working with the industrial equivalent to black tanks makes me think this flusher is not very well designed. When we want to clean out a tank, we set fan spray nozzles so they sweep the floor of the tank towards the drain. You can have dried / caked material laying in there and it's gone in seconds.....but I don't want to tear apart my new TT and re-invent the system......
Headed back out to drain again.
Be careful with the way you are doing that or you may burst your tank! If your blank tank rinse is like mine, you are not supposed to use it with the gate valve closed...too much pressure or a blocked vent and you'll have a burst tank. Having said that, I will close my gate valve for a minute and then open, repeating the process while letting the rinser do its job. I would suggest you get a clear elbow attachment to go on the sewer hose connection so you can monitor what is coming out. Fill it with water and load it up with an enzyme digester....let it sit for as long as you can. Good luck!
