My wife uses copious amounts of TP and as much as I admonish her about it I lose the battle. I have had clogs because of it before. My current trailer has a black tank rinser and I use it every time I dump. I also have the wand to stick down the toilet and use it every few times and I am always amazed at how much more stuff is rinsed from the sides of the tank. The tank sensors work properly after that. All I can say is its your tank and you can dump how you like to dump just don't make a mess at the dump station for others to deal with.
