TL;DR: If your RV black tank sensor reads full after dumping, the tank is probably empty but the sensor isn’t clean. Most probe sensors work by electrical conductivity.

TL;DR: Your RV black tank flush system is a built-in rinse port that sprays pressurized water inside the tank after you dump. It clears leftover waste, keeps sensors accurate, and cuts down on odors.
